Thanks for watching! There really is no "better" for overdrives, just whatever you think sounds good. I have a video comparing 14 different op amps if you're interested, link is in the description for this video.

Thanks for watching! Great to hear you liked the tones from this pedal!

Thanks for watching! Great to hear you enjoyed the video, thanks for the kind words!

Thanks! I'm trying to build a fan following for this chip! ;) Check out my RAT op amp shootout, this chip really sounds awesome in a hard distortion/fuzz circuit!

Thanks for watching! And thank you for sharing your listening impressions!

YES!! Love Guyatone!

Hi Dan, thanks for checking out my videos! And thank you so much for your kind words, I really appreciate it! The editing always takes up a lot of my time/effort so it's nice to get some positive feedback :)

Thanks for watching! Yes, the Guyatone pedals have a really cool look to them, with the fonts and color choices! And yes, this pedal sounds great!

Thanks for watching! I've never tried the EHX Hot Tubes, but yes, as you've noticed with the brilliance all the way down it sounds very full range super fat!

Thanks for watching! It depends on your image of "tight," but if you want to adjust the low end response, check out Episode #2 of this series!

Thanks for watching! And thank you for your kind comments! Great to hear you enjoyed the video, and congrats on your GE10 purchase!

Thanks for watching! And thank you so much for the kind compliments! Great to hear you enjoyed the op amp comparison!

Thanks for watching this one as well! Great to hear this video was helpful to you, thank you for the kind words!

Thanks for watching! And thank you for sharing your diode pick with us!

Thanks for watching! Aria のペダルは結構安く中古で手に入れることができるので、回路が簡単な Overdrive/Distortion 系は改造して色々遊べますよ！

Thanks for watching! And thank you so much for the kind words, I really appreciate it! Great to hear the video was of some help!

Hi, thank you for offering your thoughts and suggestions! I went back and tried it, quick answer is, nothing changed. Played: a sine wave, a mono jazz recording, and a regular stereo song. Tried both the rear line in, and the front aux input. Also tried both the line out and rec out, but unfortunately, they all came out unaffected. Thanks for the cool suggestion though!

Hi, thanks for watching! Yes, I'm definitely toying with the idea of making this into some type of pedal when I find the time.

Hi Phil! Thanks for watching! Yes, it would make sense to plug in an acoustic guitar that has a pickup, since you wouldn't need a cab/amp simulator. Would love to hear from someone who actually used one of these.

Hi Justin! Thanks for watching! That thing is so cute, isn't it!? I definitely want to convert it into something smaller like a pedal, not sure how easy it'd be though ;)

Hi Patrik! Thanks for always tuning in! Yes, Technics was one of those brands we dreamed of as a kid. I definitely want to do something fun with this!

Hi Sid! Thank you so much for always checking out my videos and the kind words!! I really appreciate it, and it's really encouraging :)

Thanks for watching! Yeah, we're all hoping for a WAZA GE-7 :)

Thanks for watching! As far as I know, the current version JRC4558 is used in Maxon OD-9s and Ibanez TS-9s being sold today, but I have heard that some reissues in the past had different op amps.

Thanks for watching! And thank you so much for the kind compliments! I really appreciate it! Yes, hearing how the cold clipper affects lower gain overdrive was really interesting.

Thanks for watching! Unfortunately, the 2604 has been discontinued for a while now, and there have been many reports of fakes popping up on Ebay and the likes. I really don't know how what your best option would be.

I don't think it changes the sound much, but it does mean you don't have to use decoupling capacitors between the opamp stages and you can bias them together instead of independently. So It saves you two caps and a resistor.

Thanks for watching! The simple answer is; if you connect it to ground, you won't get a useable signal out of the pedal. Without getting too technical, Vb is a DC bias voltage that is used as a "virtual ground" while the signal travels through the two op amp stages. As the viewer above has touched upon, unless you decouple the signal and bring it back to "true ground," you want the signal/circuit to reference Vb as if it were ground. I talk a little about virtual ground in my "Breadboard Overdrive Build Part 3" video around the 32min 43sec mark. Hope this helps!

Thanks for watching! I really appreciate your kind words! I'm not 100% sure, but if it's "Guyatone" branded, you need a step down transformer. If it's a Nady or Westbury, you should be fine. The required voltage should be labeled somewhere on the pedal. Hope this helps!

What stepdown transformer would you recommend to use with this pedal??

@@TanekHeath It doesn't draw that much current, so you'll be fine with almost any transformer. I'm not familiar with any specific make/model since I live in Japan and don't need one. Hope this helps!

@@arito Nice I'm thinking of picking this up soon. this pedal IS just the TD-1 with a bass and treble knob right?

@@TanekHeath Not quite, but they're very close. I talk briefly about their differences in the video, but I've never owned a TD-1 so it's all based on information I've gathered.

Thanks for watching! And thank you for sharing your impression on the tones! I hope you enjoyed this deep dive comparison :)

Thanks for watching! And thank you for the kind words! Great to hear you enjoy these videos! Thank you for sharing your impressions, yes, the CA3260 in particular seems to have a nice clarity to the notes.

Thanks for watching! I hope you enjoyed the video!

They sounded the same? I am usually thinking there's no magic op-amp and I do not like cork sniffery and the way the marketing hype affects prices, but all these chips sounded a little different to each other. I was quite surprised.

Thanks for watching!

It's not critical. Visual Sound replaced it with a chip that wasn't even an op amp and the difference was imperceptible. So minute that you couldn't tell a difference in a blind test.

@@J.C... I used to think that way after having installed solder tails into many devices, but eventually over the range of a device's variable operating specs it becomes obvious. I only use my own original circuit I call the Death Screamer Overdrive for what it drives many amps and pedals into, and once in a while I'll notice something is wrong with it, start inspecting it's now catastrophe of insides from 50 different modifications, and typically when this happens, I'll suddenly notice I forgot to switch the chips in it back to "stock". If a 4558 of any series is in it, I know for certain just from hearing. Things get far more extreme as well as obvious as you graduate up the ladder in engineering with experience aside from grander knowledge.

Thanks for watching! I'm guessing you skipped through the intro part of the video, but I briefly talk about the TD-1 around the 1:50 mark.

thanks so much sorry about that. I did go back and listen…. Love your stuff.

@@nunziosignore5264 No worries! Thanks for your kind compliments! I've never owned a TD-1 so my knowledge is very limited, but I hoped that helped!

Thanks so much!!! I really appreciate your kind comments!!

Thanks for watching! It's hard to tell, but I would start by carefully triple checking all the connections. I'm sure you've already done so, but a lot of times it's the most simple overlooked connection that causes problems. Next check resistor values as it's easy to get the color codes wrong. Otherwise, I would suspect a bad capacitor. And if all those seem fine, it could possibly be a bad op amp. Hope this helps!

Hi Dan, thanks always for checking out my videos! And thank you so much for the kind words, it's great to hear from folks who enjoy my videos! I really appreciate it!

Thank you so much for the kind words! I really appreciate it! Great to hear you enjoyed the video, thanks for watching!

@@arito Thankyou most of all! This is a super high quality comparison that many people would have been wondering about otherwise. As a pedal builder I am so glad to have found your other videos, please keep them up!

@@ArrakisOCE Thank you! That is so great to hear that you enjoy my videos, I hope they are of some help to you! This one in particular was a lot of work, collecting all the op amps, but that was also part of the fun :)

4558 is just a jelly bean opamp tho. It's not even specified for audio. However, guitar world is such a total opposite of Human evolution which whom tend to find a way to improve everything by nature. I mean just look at the latest T.I's or Analog Devices opamps catalogue, today's opamp design tend to avoid distortion (measure in T.H.D) at all cost! But why 4558 still in production (for over 40 years!) even for today's standard? Because the demand for insanity called "Mojo" would be still exist for next 100 years.

Thanks for watching!

@@ninocarlitos5229 Thanks for watching!

Thanks so much for the kind words! I really appreciate it!

Congratulations!

Great guess! Yes, as you mentioned, the mod has a little harshness from the op amp clipping.
