    I have a 1971 Fender Twin-Reverb that came stock with two D-120 JBLs. Amp also came with removable casters as well, which made for easier transport. I worked one summer at the JBL factory in Anaheim, California. I glued cones and spiders onto frames (cones don't "blow"; the coil could get hot while moving through the magnetic field and then short out); glued the silver dust caps onto cones; magnetized magnets; bolted magnets onto frames; pressed labels onto said magnets. Fender was located in nearby Fullerton. Once I dropped a magnet on my foot and it felt like my toes had been sheared off. Fortunately, I was wearing Red Wing boots. I still have the amp but it needs to be re-tubed. Thank you for the well-researched history.

      Those Twins sounded excellent. I remember looking to rent a Twin, where they had one installed with JBLs and the other installed with Altecs. The JBLs sounded excellent but I went with the Altecs Twin for my purposes. I was surprised to find that Pete Townshend's HIWATT setup included 2 - 4 x 12 HIWATT cabinets - one installed w/Fanes, the other installed w/JBLs. I thought wow, so that explains how he got that incredible sound, sort of caused me to rethink my HIWATT setup!

      I have a 1965 Twin Reverb and took the original speakers out and replaced them with a pair of lightly used original d120’s I got off reverb. It’s crazy how much they sound like THAT sound just by changing the speakers. My favorite thing about them is setting the amp where it’s naturally compressing and playing some rhythm with it, mostly 3 string chords that have a wound open string in them against the fretted strings, it just sounds perfect for that stuff.

    I notice others have also pointed out that you didn't mention the Grateful Dead as users of JBL, their famous Wall of Sound used JBLs, and earlier than that they had most of their amps were refitted with D-120s I think the Dead were pioneers in trying to make front of house sound as hi-fidelity as possible and JBL were definitely a part of that quest.

      In 1975 I ordered a 2x12 Alembic cabinet with 2 JBL K120s directly from Ric Turner at Alembic who made the Dead's cabs that were the Wall of Sound. It was amazing, sounded great. He shipped it all the way to my apartment in Boston. Still have the cab, took out one of the K120s to put in my 1980 Princeton Reverb II which I play to this day, sounds much like Zac's Deluxe, sweet, pure, clean, open, and btw takes pedals great.

    I've been a JBL fan for far longer than I've spent trying to learn how to play guitar. On Ebay, I found an E-130, designed and built my own cab, and covered the grille with Fenderesque cloth. Powered by my one watt tube amp, and my Stewmac Ghost Drive, I am a mediocre Strat player, with the tone of a rock star.

A couple of years later, while I was in college, I took out the Vox Bulldog speaker (not a real Celestion), and put in a 10" JBL musical instrument speaker. I have had the speaker reconed at least once, and it still makes that little Vox a killer amp.

    A JBL 15” speaker is a thing of beauty. I started with a Weber replica and eventually stumbled on a modern Standel 1x15” cab with a custom JBL style speaker. Amazing warm clean tones.

    • @christophergallagher531

      I found Ted Webber's to sound on the order of Altecs, also the pressed frames where prone to warping. One had to be careful torquing them to the board.
      The CAs I had, had tight gaps and could get to rubbing. Two points for cast frames.

    Yeh, a D-120 is THE super clean speaker, with an incredible array of frequency production as well. I have both a D-120 and a D-130 hanging out in my closet, both needing to be reconed, plus a Fender cab with two D-120 orange frames which sound incredible! Vibrasonics were awesome and rare. Essentially, a PRO with a bigger output transformer and a D-130. That coated surround seemed to allow the cone to travel further without knocking out the voice coil. The Dual Showman was a toneful powerhouse! Yeh, those connections were also backwards on their studio monitors in the early '70s .... The attack response is very fast! One of THE best rhythm sounds you will ever hear, is a Gibson 335/345/355, through a single or dual Showman with one or two D-130's, similar to the sound of The Airplane's, "Don't You Want Somebody To Love." Incredible drive. Tonetwisters, over and out ...

    A couple years back, I bought a Standel 25L15 Vintage Plus with a JBL D130. The first couple of times I played through it, I thought “Uh oh. What did I get myself into?” Very responsive and present and unforgiving. Nowhere to hide. Steep learning curve, not just getting a good tone but actually being comfortable playing through it. Glad I preserved, cause I can’t imagine it not being in the collection now.

    As the house mouse at my local music store, I saw a few JBL equipped twins come through in the early 70's. Mostly for people who played pedal steel. The shop always had at least three steels on the floor. Emmons earlier and then they switched suppliers, something like Mesa maybe. Can't remember. I passed on a black face with two JBL's in it that came in on a trade. Not proud of that. I still have a '76 silver face Twin from that shop, and a '67 Epiphone Olympic, but the most important thing I have from there are the lessons I learned from Rick Hannon about how to treat people.

    I have formed the hypothesis that, the bigger the magnet, the more of that harshness or clang or whatever is perceived when solo'ed, but in a mix the same harshness is great plus all the other benefits of the big speaker from dynamics to clarity to low end etc. When for example I compare medium magnet greenback-types to heavy magnet ones, I hear a sweetness in the highs of the medium magnet, along with a compression and blurriness. The heavy magnet of the same structure, gives you power handling, dynamics, clarity and that signature so-called harshness that stands out in a mix. The EV Coffee Cans I mentioned in a prior comment, have superlatively enormous magnets in them, and they have the "JBL harshness" in spades. Same goes for the Eminence red coat wizard I have in a fargen. Yuge magnet = "the JBL sound."

  • @angusorvid8840
    @angusorvid8840 2 роки тому

    What I love about JBLs is that, like EVMs, they are very transparent. They don't color the sound like a Celestion. I've used all sorts of speakers but always enjoyed speakers that let the true sound of the amp come through. A speaker should just assist the amp in getting the true tone out, not coloring it. Always keep in mind that mics will add their own variable in interpreting what comes out of the speaker. I tried a Dumble Overdrive Special at a boutique shop in '87. It was a 150-watt head and a cab loaded with EVMs. It sounded incredible. It was so clear, even at very high volume. You heard the real gain of the amp, not a coloration from the speakers.

    Great video! I'm 70 years old and put JBL's in all my Fender's back in the day starting with a D-120 into my original mid 60's Silverface Princeton Reverb which I bought new. I was never happy with the original speakers that came with them because I didn't like the frequency response. Not only did you get a 3db boost in volume due to the speaker efficiency but it also equated to being able to turn the volume up more without it distorting. This was a slight problem with rock and roll until Dallas Arbiter from England came out with the original Fuzzface with the geranium transistors that can be heard on Jimi Hendrix's first two album. While the Maestro Fuzztone from Gibson which was the first fuzz made was available it didn't sound as good. This was first used on 'Satisfaction' by The Rolling Stones. With the Fuzzface it evened the bar with guys that were using the stock Fender speakers which varied in manufacturer quite a bit. I later used the K series when the D series was no longer available. Personally I liked the K series better but most people like the D. The K and D both used Alnico magnets. With the introduction of the E series they started using ceramic magnets which drastically changed the tone. That said, the E series sound better with acoustic instruments.

The thing sounded incredible but even with my friend it was so heavy it was difficult to put it in the trunk of my mom's Chevy Impala. I did one gig with it and sold it and bought a Silverface Princeton Reverb. My friend made a new baffle board and we put a D-120 in it. Much easier to move and the D-120 gave me a lot more headroom so it worked for all of the gigs I had which at that time were mostly high school parties. That said I'm really sorry I sold the Twin even though now my Quilter Steelaire sounds just as good if not better.

    My amp is a Standel 25L15 circuit I had made by a great local amp builder. I looked for months before I found a clean all original D-130 for it.
    It sounds phenomenal. Although the amp is only 25 watts, it is LOUD. It is also extremely clean all the way up till about 8 or so. I typically play it at 3. In the bedroom about 1.
    One thing about the D130 is they were widely used as a hi-fi speaker. They are really impressive in that realm.
    I do think the paper cones sound better than the cloth. I’ve read the copper windings in all the D130s were hand wound which contributed to their high price and eventually their demise.
    Finally, if you decide to go the 15” JBL route have a strong back. They are heavy!

      Still I would venture Jerry tone drives the prices on vintage 12" JBLs, none of those other players mentioned, as it's a key tonal aspect of his sound. Aside from all the hippy culture BS, Jerry's playing is worth a listen. Europe '72 and One from the Vault or Tree from the Vault are great examples of the JBL sound. For acoustic playing Pizza tapes with Tony Rice and David Grisman is killer stuff. AND we haven't even mentioned his pedal steel playing! Ask Don Kelley graduate Daniel Donato or John Mayer what they think of Jerry's "jamming hippie" playing sometime.

      I was talking to an amp tech today, apparently a lot of those old Kustom 200Watt Tuck & Roll heads still function and still sound great, people swear by them, guitar and Bass
      and if the proprietor of Kustom spec’d JBL’s for the cabs too those amps, the amps wide use and reliability seems all the more plausible. Good choice, & they weren’t cheap, and weren’t light
      Me personally?, the JBL’s mid bass, sounds too flabby, the high end too piercing….with a guitar? Cone movement? Dunno? On the other hand, any bass sounds better through any JBL, any size, the only speaker that comes close to an old school JBL 15, is an EVM 15L Guess EVM’s are just what my ear wants to hear,
      My 70’s Altec 12” is also a little too strident for me, (but great mids & Lo’s) although I play through it nightly almost. I use it with my EVM12 , set to very clean and a couple of DB lower than my distorted tone, fabulous definition both 12”’s together that way, combined. But I’m getting spoiled using both, but I don’t gig out anyway……so I finally decided to just play both, always …🤓🙂

By the 1980s, JBL had responded with the criminally underrated MI- series, which are voiced more "normally" and sound pretty much perfect IMO -- but like their predecessors, they had heavy cast aluminum frames and hefty price tags, so they never gained any traction to speak of with guitarists and were soon discontinued.

I remember in 1973-‘74 this guy at a shop sold me on Cerwin Vega guitar speakers saying that you get more volume, better sound and better quality for my 2x12” Carvin cabinet and the whole nine yards. After I understood through a more honest shop owner about efficiency not being good to the ear like Celestions are, my Cerwin Vegas got used in monitor wedge cabs. Where I really could’ve used them is when I blew the cheap CTS speakers in the Carvin cab when they sent me the 100 watt head instead of the 80 watt I ordered in 1970. Maybe if the speaker handling capability was figured extra close because of cost $ is why they blew in mine and an identical cab belonging to a friend of mine.

    I was driving down the street one Sunday in the early 90’s and saw one of those notoriously badly designed mid-late 70’s 135 watt Fender Twins at a yard sale for $350 which I bargained down to an even $300. It had orange D120F’s in it. The amp and speakers were really still like new. Original owner told me that especially with the heavier transformers for the 135 watt power section and speakers-it made the amp extra heavy, he stopped using it and got a Music Man leaving the Twin sit. After soldering a broken solder joint on the reverb tank, the amp was fine. The Alnico in JBL’s and Altec’s magnets wear down over time-different examples of ones I have, prove that sound wise-not sure if it’s that “half life” I’ve heard about or speaker vibration or whatever. These in this Twin were showroom new sonically and physically. As far as that weird sound Zac describes that JBL’s make-a local amp builder/tech described it as a “tinking” sound. It think it could be because of the aluminum dust covers. Tapping the dust cover reveals that. As Classic as D120F’s/D130F’s are-they’re not for me, they’re too efficient sounding and of course I don’t like that harshness they have. They’re great for being clean sounding though.

Somehow they had some cone cry going on, and I never had that with any other speaker. Also there was debris that got into the magnet vent, but I managed to vacuum clean that out. Anyhow, it's a specific sound that can be great if that is what you're looking for. I thought they sounded best for cleans, but a lot of players have used them with their Marshalls too.

I'd heard about JBL speakers being "unblowable", so I found a used D131 in the want-ads and bought it for like $30. That speaker served me well in that amp for several decades. Great clear tone. Alas, I sold the Vibrolux a few years ago to a good friend who has a nice collection of amps. I've downsized to a Vibro-Champ and Princeton-Reverb.

  • @robertbaron3242

    I'll add that Terry Kath the original and highly underrated guitarist for Chicago used Fender Showman's with D130F JBL's.
    I played in bands starting in the mid 60's through the early 70's and JBL was the dominant premium speaker used by most lead, rhythm and bass guitar players. Usually, one had a Fender amp with Jensens because they couldn't afford JBL's but they still coveted them.
    James B. Lansing created some of the first precision loudspeakers. As you mentioned most (all?) paper cone speakers of that era were stamped steel frames with small voice coils and magnet structures. The critical surfaces of JBL's cast aluminum frames were machined to precise dimensions. The voice coils were 3 inch on the D120F and 4" on the D130 and 140F which was twice the diameter of competitive speakers at the time. JBL also used edge wound ribbon wire in their voice coil windings further aiding in efficiency.
    Something not mentioned was that JBL also was the dominant studio monitor of that era. When the musicians mentioned by Zac went into the studio to record they usually saw and heard their playback though JBL monitors. When James B. Lansing developed his first 15" coaxial driver (speaker that incorporated both the low and high frequency drivers within the same frame each with it's own voice coil) in the 1940's Bing Crosby was so amazed with the sound of his voice played back though it he insisted on using it for all recording sessions.
    Great video and a walk through memory lane for me.

    Great info, the curious part is that Altec was JBL’s hi fi competition back in the day, in fact they split off from JBL, late 50’s I believe, over design philosophy differences, their design was stiffer, less cone movement, deeper cone, smaller aluminum dust cap, I was lucky enough to get a 12”, and I put it in a Theil cab, but unlike my EVM 12L (same cab but even stiffer, less cone movement in an EVM) I removed the middle port opening to let it breathe/move easier, it’s a great cab for bass or guitar….🙂
    But I read later that Santana used them in his early Boogies, and more recently Randy Rhoad’s used them in quiet riot and for Ozzy in his closed back stacks. I also inherited 2 15”
    Altecs…..which I use daily as part of my stereo system, they replaced the blown 15’s in a big 60’s sealed back Jensen design, no port, makes for a tight, deep lo end. Doing that with JBL’s would likely ruin them, JBL’s need a port, lots of cone movement. I have a bunch of smaller vintage JBL’s I reconed , some 8” ers with the Crinkle powder coat magnets, and the old oval emblem, some K110’s but also one older series 1 10”
    But my EVM 12L is my main guitar cab, nothing else compares for me, it sat needing a recone for years, but the minute I payed it again, I gave up on the Boogie Black shadow and the celestian. I like the celestian’s in a 4 x 12, but at 66, I’m not likely to lug a 4 12 anywhere, only if I played outside….I don’t like open back cabs, or combos, too loose, not focused enough, but great sounding for thin piercing country type licks. I like a lo mid thick focus, Santana style but a bit more gain for my less physical weaker hands. I wonder if there is much history on players who used Altecs, before they were in my stereo , they were in guitar cabs from the 60’s!

    I used a JBL 12 in a Deluxe Reverb back in the Eighties. It started making weird noises. I observed that the aluminum dome had a hole in it (where there had once been only a dent), and it then proceeded to tear itself apart. Got weirder with every gig, so I eventually tore off the dome altogether. It looked ugly but I thought at the time that it sounded better. Eventually, I had it and another JBL re-coned with paper domes. I loved 'em.
    For me the quintessential JBL sound (with aluminum domes) are the solos on the song 'Southbound' from the Allman Brothers 'Brothers and Sisters' album. Dickie has really got the "beer can" sound of those domes goin' on.

I too love JBL D series speakers. my first ones came in my used at the time 1969 fender Dual Showman Reverb with 2 JBL D-140's I just love those with my all original 56 Stratocaster, oh yes. Any of my guitars in fact sound excellent with them but I really do like the 140's I think more than my D 130. There is more or a fatter bottom end to the sound especially with a thinner sounding Strat. Don't let anyone fool you D140's are fine with guitar as they are with bass too.. I think they called them extra heavy duty upgrades. moving on I also a few years ago found my blonde 1961 Fender Showman serial # 573 and I have a JBL D 130 in that cabinet. also amazing sounding. My first amp with A JBL was a 1959 Fender Vibrasonic the brown one serial #197 with a factory installed JBL D130 in it. My mistake was selling that amp in 1994 for it is worth a fortune now a days. even in 94 I sold it for more than I paid for it in 1986.... Then a couple years ago I went on a hunting mission and was able to find and install a bunch of JBL's in quite a few of my amps.. In my 2010 Tweed Fender blues Deluxe I now have a JBL D131, my understanding was that the 131 meant the voice coil and the guts of a 15 inch in a 12 inch speaker less chance to blow it up. Hopefully. then I was able to buy from the 1950's 2 JBL D 123 speakers just great sounding speakers I put them into 2 of my Fender Blues Jrs' one a blonde 2001 the other a 2012 Tweed one with lacquer on the tweed they sound incredible now and then I also found and bought 2 JBL-D 110F speakers and installed them into 2 of my 3 tweed Fender Pro Jr's a 1194 and a 1995. also incredible. lots more headroom in all those amps now. I left my 66 Princeton reverb alone kept it all original and for the 15 watts size amp I am preferring those Little Pro Jr's and Blues Jr's right now over my 12 watt Princeton reverb. my first bigger amp as a kid was back in 1975 When Music Man came out I bought the 65 watt head and had a custom built 2- 12 cabinet made that I had electro voice SRO speakers in. they sounded great but I always felt the JBL's were just warmer tighter bottom end. both were high effect though. that amp got to heave y to move to gigs so I sold it and bought the 2010 Tweed Blues deluxe and now2 with the JBL D 131 in it it sounds fantastic. I also have a pair of 1994 Tweed blues Devilries with the original blue Frame alnico speakers in them. and those amps sound excellent too. and my 77 marshal half stack with the 50 watt head and 4/12 greenback 25 watt celestions. yea I have spent a lot of money upgrading a lot of my amps but I feel it is well worth it for they now ALL sound as good as they can. and yes JBL's don't lie they put out just what you put into them. Oh yea almost forgot I HAVE 2 CARPETED CABINETS WITH TILT BACKS ON THEM WITH JBL E120's in each one, They sound good too but Not as sweet as the original D series JBL's do. and t hat OK stay safe and healthy, Mike in Phoenix...
