- The stock components don't really cut it on bass, so I've been experimenting a little to understand what suits better. Enjoy!

You my friend are amazing!! I never thought how important a tone resister is .. Fantastic! Now i must go on my journey to find my tone! Thanks
This is a very intelligent Video...sometimes little changes in small components can save big money in searching for new bass, just get the best from what you get ... very well done mate.
I would have liked to see how the low notes respond to the resistor. Trying to tighten up the low end of a baritone guitar.

I am sorry, i am a beginer on playing bass. I try P Bass last time. I wanna ask, is it the tone pot/knob work only full volume? Or I just can find the different?
Awesome video! How do you have that set up to try the different capacitors? Lol I'd love to make one.
Are used this on my 79 Precision. I think I wired it correctly but when I turn the control clockwise past the center it adds 50% more volume and a little more treble. When I turn it counter clockwise past the center it seems to lose volume and bass.
I have a 1985 Jazz Bass Special with the tbx. I also have a 95 Strat with it too. I actually like it a lot. But on the bass, I just leave it in the detent, in the middle. I notice the high frequency filtering a little, but I just use it as is. I don’t understand the stuff you are describing about the electrical, but I enjoyed watching the video.
Spiegazione perfetta!
Excellent content! Congratulations!
Do you know the value of the capacitor and resistor that originally comes with the models below?
Fender Jazz Bass Special (80's made in Japan)
Duff Signature (made in Mexico)
Duff Signature Deluxe (made in Mexico)
Fender Jazz Bass Special Reissue (made in Japan)
Another question I have is whether the TBX kit that Fender currently sells for guitars can be used on a bass? It is also 250K/1Meg pot.

Hi, sorry for the late reply! If I remember correctly the cap is 22nF in every model, which may make your bass tone a bit muddy but some people prefer it that way, the resistor is also 82k in all of them.
The TBX pot is the same in both guitars and bass, but as I mentioned in the video I believe it is necessary to tweak it a little bit like using a 47nF and a 120-180k resistor
Very useful thank you
Would this TBX compare to the recent EMG EXB Tone control you featured recently on your channel?
Not really, the name is similar, but the TBX is essentially a "glorified" 1Meg tone pot, and the EXB is more of an active tone, which has its own eq
"the bigger the glob, the better the job" ;)
Hey man, can I ask for some help?
So I've bought a tbx bc I wanna put it into my bass. We're talking seymour duncan quarter pound p/j. How do I hook it up when I got 2 volumes? As in one volume control per pickup, and I wanna use the tbx kinda as my only tone control? Mind explaining or showing me to a wiring diagram? Thanks
It's wired just like a normal master tone pot. You just need to hook it up from your output jack

The capacitor demo was probably the clearest explanation of how they actually affect the sound of the guitar. The resistor demonstration though I am not sure how it really changed anything.
It is an extremely subtle difference, and you can mostly hear it when comparing very different values
@@OliverTobyn What roughly is the difference in question?
Thanks for the great video. My '85 Fender bass TBX does not respond after about half way up, it doesn't get too bright after that. My other '85, same bass, does go up all the way and gets very bright. What could be the issue? Thanks.
Thanks for the information this is a great device for passive Bass players. But does it need different capacitor for different pickups (P, J, MM)?
Please do a longer demo with the capacitor you usually use.
Hi there! I did a separate video on capacitors, you can check it out on my channel. Different basses don't necessarily need different capacitors, it's all a matter of taste. 47nF works well on most basses. 100nF works well on a P Bass if you want that deep vintage tone. Whereas some humbuckers work best with 33 nF
Which resistor has a noticeable brightness tone 180k, 200k, 220k? I can't tell the difference.
@@melogomaniac in my experience 120k, 150k and 180k work best. 180k is very subtle and above is barely noticiable. The value of the resistor will be the starting point when you swipe trough the 1Meg section of the pot, but at higher values it's less noticeable. I'd try a 150k resistor, then from there decide if you want to go higher, lower or if it's ok
@@OliverTobyn TBX is really interesting you gave me a lot of ideas in it. I was thinking using the low pass for bass tones and high pass for bright solos. Thanks for the help!
Thanks, exactly what I was looking for. I am using a Single Q-Tuner Neodymium pickup on a 5 string music man clone ('Italian' MiC Eko MM-305). Does the capacitor or resistor need to be varied due to impedance of the pickup? Appreciate your input. Cracking open the guitar all the time is causing me some stress! I like the bass and don't want to ruin it.
Hi there! No, not really, the impedence of the pickup just tells you how many winds it has, and that can be an index of clarity or darkness of sound, but it's not always the case. So you can put in any capacitor and resistor you like
@@OliverTobyn Thanks! Going to wire up the tbx in a few days. Hopefully it will help tame the neodymium a bit (very pure tone). But as my teacher says 'Practice!' He is right, it is more important than the tech :)
@@elearninghigheredk12 yeah, though I believe it might be equally as important. I've seen so many super skilled bassists who had absolutely no idea about the tech stuff, or even how to set up their instrument. Obviously skill matters, but knowing your way around the tech stuff will definitely make you more versatile
Great video, I'm customizing a TBX tone, I would like to hear more difference in tone between the capacitor part and the resistor part. Wich resistor value do you recommend? Note that in my 1988 Fender Jazz Bass Special a resistor of 4.7nF was also put together with the tone capacitor...I don't know why
The 4.7k resistor basically prevents the tone being opened all the way, which sometimes results in a muddy tone, I personally like it because it's a deep, dark and well packed sound. As for the resistor value, the stock 82k will give you the greatest difference, but it also means that you're losing signal when it's in flat. Maybe I'd go a bit higher, with something like 100k-120k
TY so much, now is really clear!! What about he Pick ups wiring? You prefer PJ wired in series or parallel?@@OliverTobyn
Got one, wired it w/100K, and I have to be honest, I don't know what the TBX side is supposed to do. It doesn't cut bass much if that's what's supposed to happen...
Sorry for the question a bit OT but where i can find the small size japan pot tbx for power jp bass circuitry ? Have a nice day and good music all fo you
Great👌🏼👌🏼👌🏼.....Muchas Gracias
Do you have a schematic or diagram of the mod you did?
thanks, this is super helpful
Sick thanks!
Interesting, which resistor value would you recommend for guitar?
Thanks! I think what I said in the video also applies to guitar as well. The stock 82k makes it act more like a volume knob than a tone knob, and anything above 180k barely makes a difference. But it might make a bit more of difference on guitar, I've never tried. I'd probably go with 150k and work up or down from there.
@@OliverTobyn thanks, I have iron my American Standard, the effect is subtle, for the way it was explained back then it was a treble and bass "expander" in the sense it cut mid frequencies, so I was concerned it might cut too bass or that it would not be heard.
Hey Oliver can you help me install this damn thing there no proper instructions for installing to a single volume control.
Thanks.
It's exactly the same as a regular tone knob, and follow the same instructions as the Fender Jazz Special, there is only one white wire from the output
@@OliverTobyn but does ground and the input jack pos neg go to the tbx first or to the volume control ?because different diagrams say different things
@@nayr87 it doesn't matter, as long as the TBX is connected it will work. Doesn't matter in which order. Usually you'll have the white wire from the pickups that goes to the volume, then TBX and output jack. But it will work the same if you have volume-jack-tbx
Does the TBX control knob have a notch to let you know when you are at "flat" or the 12 o'clock position? Specifically curious about the knob on the Duff bass. I have also heard that the knob on the Duff bass would have clicks when you turn the knob clockwise from playing position, past the 12 oclock point. So basically when you are in the 1meg side of the pot you get a click at 1, 2 , 3 4, ect positions. Can you confirm any of this on the TBX pot on the fender duff bass? Thank you for the great video
Yeah it has a notch at the 12 o'clock position. I've had the Duff bass, and a couple more TBX controls by Fender and they all have it. They don't have any other ones at the 1, 2, 3, 4 and so on postitions. Thank you for watching!
@@OliverTobyn thank you so much. That confirms the Duff bass I just received has a bad tone pot. The sound didnt sound any different when you went past 12 oclock. Plus there is no notch at the 12 position either. Added to this was the noiseless Seymour J pickup had more hum than a standard J single coil. Gotta love Sweetwaters fake 55 point inspection. I did send the bass back for a replacement, but this just confirms what I already suspected. Thank you again, I really appreciate the video and your quick reply!!
@@mikez1975 yeah, as I mention in the video, the Duff also has an 82k resistor which comes into play when the pot is in the flat position. It kinda makes it sound more like a volume knob than a tone, so you definitely hear a difference going on there. Somehow my Seymour Duncan J pickup also has a slight hum to it, no idea why. Again, thank you! :)
Hi there, this is a great video and thank you for sharing. I just bought a Duff Bass and I'm planing on following your tutorial and buy the 180K resistor but there are so many different brands and watts .05 or 1/4 W, 5% which one do you recommend? I hope you reply so I know which to buy. Thank you in advance! @@OliverTobyn
@@pabloserranomusic hey there! I'm glad it was useful. It really doesn't make any difference if it's 1/4W or 1W as that's for heat tolerance and on a bass we're dealing with very low voltages. The only thing that really matters is the resistor value
