TLC2227CP sounds the best (more highs) to me. second the LM833, third TL072 and the worst are 062 and TLC27l2C (sounds like crap). One more time colors and tastes... Thanx!
A caveat here that folks should be aware of. These results don't necessarily reflect the overall quality of each make/model of op-amp tested here (or any similar op-amp comparison video). Distortion circuits often use these devices in ways they're not specifically designed to be used, they often work ok, and some do better than others, but the results won't be as consistent as when you're using them in a clean linear fashion. Also, your results in other distortion pedals may be wildly different depending on how the op-amp is connected to other components in the circuit to generate the distortion, so don't be surprised if the best sounding device in this video sounds like garbage on your pedal. Not a big deal, but something to keep in mind. I like when people experiment and share their results. Good video!
Thanks for the video. I liked the presence, clarity, and output of the TLC2227CP the best. I thought the JRC062D and the LM833N sounded about the same (middle of the road) overall but the 883N didn't have as much output. The TL072 was fatter and woolly. Any of the first four could be useful. I didn't care for the last one either, kinda fizzy/fuzzy.
I think the TL072 was the most 'palatable'. The JRC at one extreme, and the TLC27L2C on the other. The TL072 brought in some clarity without adding too much crispy/fizzy over sharpness. I think it is a good safe op amp most could get sounding how they want.
The JRC 062D is not an op amp! It’s an 8-bit CMOS microcomputer! I’m wondering how this is working? I like that one too. The LM 833 is a dual audio op amp. So it’s made for audio.
Like seriously just stack 'em. The trick is to connect every pin parallel chip to chip, the easiest way is simply to place chip on chip. Around 4 chips will be the max for random phase cancellations. I was working on a TS/OD-1 hybrid with quad opamps and a lot of diode switching options, but the stacking still remains the easiest way, rather than to design 4 parallel traces.
Вся разница ТОЛЬКО в яркости звука. Яркость компенсируется ручкой тона. То есть никакого смысла менять операционный усилитель в педали овердрайва нет. Разница возникает из-за разных входных сопротивлений. Сопротивление RC фильтра меняется, а ёмкость остаётся. Тот же эффект будет при замене конденсаторов на другую ёмкость. А вообще, разницу в звуке можно получить не меняя opamp, но просто меняя питающее напряжение.
Hey man thx for doing this. I commend you for making a vid that puts the audio direct vs. some folks that mic an amp in a (bath)room and somehow we're supposed to figure out the diff -- enuf of that -- but it occurs to me that putting a TLC2272CP in one stage and following it with the 062D might give you some bite and roundness too -- but the 062 def sounds like best of all worlds. Now I'm checking out trash piles to see if there are any old radios I can harvest for parts. Did get one radio that has some old germanium transistors so we'll see. Anyhow, good job. \m/
Hi, is the 833 quieter in terms of floor noise?, I heard that 2 in parallel can reduce the damn floor noise, Tks in advance 4 any comment, great video.
Great video but Im wondering, is there no need to alter any other electronics settings - is it possible to just swap them without making changes in possible bias current, feed and so on? Just a question, I don't have much experience of opamps and not tubes.
Great video.. but maybe you use too much distortion for swap. Maybe its a good idea to swap the op amp on overdrive mode, or more less gain. So we can get limit between clean and distortion for see how respond for each opamp
I found a lot of copies of original component from china and it is difficult to recognize the real ones (on ali, the logo is erased on fakes and I found only ONE seller or original products)...
After looking at internal schematic, you can replace TL972 for TL072 or LF353 as long as total supply voltage less than 15V. Product characteristics (output timbre) may be changed.
Love what you are doin' man ! HOWEVER, personally I feel that if you are demoing Op-Amp s in this fashion , I think that it would be incomplete without trying both the "JRC4558" and the "LM308N". Maybe some MOSFET too ??? Just sayin'...
Bhushan Patil Hey Bhushan thanks for watching!! The JRC chip was my favorite, but I like the TL072 almost as much. As far as the LM833 and LM4562 sounding the same, I dont know. I dont have the 4562.
thanx for reply...... i just google and download the datasheet of LM4562 from specification it looks this chip is one of Best OPAMP chips Available .... i am little confuse because i wanna build a low pass filter for subwoofer amp an thinking for NE5532N but now i am thinking to use LM4562 ......what do you thing which is good for low pass filter ...
Bhushan Patil Im not sure which one is better, but I can suggest you buy both and put an "IC socket" in instead of soldering in the IC. That way you can switch out and find which one sounds the best. Thats what I did for this pedal, and all my other pedals.
Interesting to listen to. No offense, but you could almost eliminate the first 3:00. Sometimes, people just want to get to the subject of the video. Quicker intros are appreciated. Again, not Trying to offend, and sorry if I did.
Sarah Michelle constructive criticism is accepted. There are time links in the description that go directly to the sound clips. Thanks for watching though!
That op amp is designed for clean accuracy, not 'pleasant distortion'. It would probably sound like the last two op amps in this comparison, if I had to guess. That op amp is usually used unclipped for a very accurate amplification of the input signal without adding any color of it's own. Usually it is used in high end home audio amplifiers, not instrument amplification.
Anyone have tried AN6552, CA3240, LF353, M5218, NE5532, OPA2134, TA75458? Add a 100nF capacitor on pin4 to pin8 of the opAmp to get more solid sound. Cheers from Indonesia
echo well, you can still hear a difference in the opamps even though its going through 914462 transistors, and that was my point, so, its not pointless really. But, thanks for watching.
This is really stupid, you engineer a circuit around an opamp, you don't just swap opamps with completely different specifications hoping they will work in whatever circuit. These are opamps, nothing like tubes where you might try to find a pleasant distortion sweet spot.
And of course in general you can happily swap opamps to upgrade and play with performance. IF you are CAREFUL, there are of course exceptions with supply, stability issues etc. keep an eye on data sheets. Yet opamps were and are designed for specific applications, and those based on the basic 741- as many are - can be dropped into circuit - and your noise and distortion figures can drop orders of magnitude over a crap device designed to be a cheap thing in the late 60s to a state of the art one designed recently. Ben I don't think understands these devices.
Ben Adams is right, "rolling op amps" is generally not a good idea, because the circuit itself has to be designed for a given op amp. Op Amps can develop instabilities in wrong circuits.. they can oscillate (like when you don't want them to) or they could have different gain properties and they could be slamming into rails and over driving, the circuit could also be biased wrong for the given op amp and you could be getting much higher noise than you should be... So it's generally not a good idea to roll them unless you have proper equipment to measure how you're altering the operation of the om amp in this particular circuit. With that said, since this is a guitar effect, and many guitar effects sort of rely on the imperfections of electronic components.. have fun with it. Just know that you might be making things much worse for the op amp you put in.. etc..
Ben Adams - This isn't stupid at all. I'd agree with you if this were a home stereo or other product that might require the inherent properties of a specific device which the circuit was designed around in order to be stable and function properly, but this is a freakin' distortion pedal. It's made to be noisy and nonlinear. Most of these pedals are engineered completely around experimentation anyway, without any regard to stability optimizations, feedback compensation or complex loop analysis. If he experiments and finds an opamp he likes the sound of better than the original what is exactly stupid about it? Nothing. It's awesome. I know I'm replying to an ancient comment, oh well.
I liked the sound of the TLC 27L2C much brighter sound IMO
TLC2227CP sounds the best (more highs) to me. second the LM833, third TL072 and the worst are 062 and TLC27l2C (sounds like crap). One more time colors and tastes...
Thanx!
Agreed, that JRC062D kicks the pants off the rest
Yeah, I like the JRC too!!! Better, smoother sound..
Foooooor sure
Thanks for posting this video! As an EE I find this very interesting and need videos like this for applicable knowledge

Thanks for watching!! Its interesting how people like different things.The JRC062D was my favorite, but I will agree, the TLC2227CP does sound nice.

JRC and TLC27 for my taste

The LM 833 is a dual audio op amp. So it’s made for audio.
Enjoyed it. Ever tried parallel chips? As in piggybacking them. Works wonders for noise issues.
Nope never tried that. How would I go about doing that?

Nightingale1887 interesting idea, nightingale. Thanks.
Sarah Michelle thanks, oddly enough he removed his comment? The odd thing is, this is common in HiFi but never seen in pedals.
Did I remove a comment? I dont think I did.
Very helpful.Exactly what i was looking for!Thanks.

The LM833 sounds the more subtle and less aggressive to me.
You can try CA3240, LF353, LM358 and MC1458 too.
Cheers from Indonesia
Great video but Im wondering, is there no need to alter any other electronics settings - is it possible to just swap them without making changes in possible bias current, feed and so on? Just a question, I don't have much experience of opamps and not tubes.
Im sure you could change some stuff around, but its easier to pull one out and plug another in.
may i know resistor and caps brand? im try to stock component for making pedal, thx
TLC2227CP The best! Hope you got a schematic for this!
Thanks for watching! This was an Eternity clone kit from Tayda.
Would have been interesting to see a 1458 and a 5532 in the line up. One circuit does not fit all op amps
Great video.. but maybe you use too much distortion for swap. Maybe its a good idea to swap the op amp on overdrive mode, or more less gain. So we can get limit between clean and distortion for see how respond for each opamp
На овердрайве разницы между операционными усилителями не будет
4558 and 5532???
I found a lot of copies of original component from china and it is difficult to recognize the real ones (on ali, the logo is erased on fakes and I found only ONE seller or original products)...
Can anyone tell me if I can replace a TL972 for a TL072?
I want to know that too..
After looking at internal schematic, you can replace TL972 for TL072 or LF353 as long as total supply voltage less than 15V.
Product characteristics (output timbre) may be changed.
Are those sockets for the diodes as well?
yes they are. I always socket my ICs, diodes, and transistors.
Love what you are doin' man ! HOWEVER, personally I feel that if you are demoing Op-Amp s in this fashion , I think that it would be incomplete without trying both the "JRC4558" and the "LM308N". Maybe some MOSFET too ???
Just sayin'...
DAVID-PAUL BEAZLEY-Jr. if I had them, I would!! I just used what I had. Thanks for watching!
hello great video .... i wanna ask hows the JRC Chip Performance ...... and can you tell the diff between LM833 and LM4562
Bhushan Patil Hey Bhushan thanks for watching!! The JRC chip was my favorite, but I like the TL072 almost as much. As far as the LM833 and LM4562 sounding the same, I dont know. I dont have the 4562.

Yaa the ic socket idea is good to try out this opamps... thanx for reply...
TLC2227CP only !

What about the OPA2134? You did not test it.
That op amp is designed for clean accuracy, not 'pleasant distortion'. It would probably sound like the last two op amps in this comparison, if I had to guess.
That op amp is usually used unclipped for a very accurate amplification of the input signal without adding any color of it's own. Usually it is used in high end home audio amplifiers, not instrument amplification.
Thanks do doing this video
No problem. Thanks for watching.
TLC2227CP for me!
Anyone have tried AN6552, CA3240, LF353, M5218, NE5532, OPA2134, TA75458?
Add a 100nF capacitor on pin4 to pin8 of the opAmp to get more solid sound.
Cheers from Indonesia
100nf just for psu filtering. Add 100uf and 100nf in paralel for reducing hum from psu source
It's pointless... Runing pedal through HD400... which has 914462 transistrors, OP Amps and stuff.
echo well, you can still hear a difference in the opamps even though its going through 914462 transistors, and that was my point, so, its not pointless really. But, thanks for watching.
Really, any quality loss from the 914462 transistors, opamps and stuff in the HD400 is nothing compared to UA-cam audio quality (192 kbps)
These people and their comments, does it really add to the sound quality NOOOOOOOOOOOOOOOO !
huckfin 1 well it kinda does add/subtract to the sound quality. Slightly, but there is a noticeable difference.
This is really stupid, you engineer a circuit around an opamp, you don't just swap opamps with completely different specifications hoping they will work in whatever circuit. These are opamps, nothing like tubes where you might try to find a pleasant distortion sweet spot.
Well, thanks for watching anyways.
