Always teasing with the Ethos pedal....

You'll find a few of transistor based ODs on Chuck's Boneyard section of the forum. This one is my favorite: https://forum.pedalpcb.com/threads/this-week-on-the-breadboard-animals-diamond-peak-overdrive-with-some-mods-of-course.13466/

Hello everyone! I'm evaluating alternatives to move away from Eagle and after a bit of a hard time with KiCad, I'll be trying Diptrace. Do you guys have a library that you recommend for pedal schematics/pcbs? Thanks! Edit: found szukalski's library

Nice one, as usual, Chuck! Any particular reason for the selection of the clipping diodes?

Is the little black plastic thing hiding something worth hiding? Or is it just magic diodes and a few hand selected capacitors

If I remember correctly, the desolate fuzz is extra picky of the jfet used (i.e. not every in spec j201 will work). I think this has been discussed on the forum

Chuck D. Bones (the mind behind the Mojito Deluxe) has explained here why he chose to use the BA482:

That was my best guess, as well. Thanks, Robert

Following @andrewsrea nice build report (link here) of a Median Compressor, I've checked the schematic and was left a bit confused by the amount of buffers this thing seems to employ (schematic here), most notably the two built with IC1.1 and IC1.2. I can see the advantages of using a non...

Could you guys please share Vp and Idss in your 2sk208-R? I have a few 2sk118-R that I hope will fit in this circuit (I know I can find 2sk208-R to buy, but I'm not ready to deal with Mouser shipping right now 💸 😆) And if you could share the specs of a 2n5458 that works in this circuit, it...

From what I understand, almost all of the sound we associate with the Sunn Beta comes from the preamp, and the power amp is there to provide clean and linear power. Your powered speakers/monitors can do that. I think you'd be fine feeding from your Sunn Beta straight to your IR loader. On a...

Do you plan to trace it yourself to check if the schematic on FSB is correct? From youtube videos, the O2 might be my favorite

Do you guys know what the J177 is doing between gate and drain of the second jfet? That's one of the things I can't seem to simulate with LTspice

Disclaimer: it's entirely possible I'm wrong. With that out of the way, I don't think it should matter as much as you're reporting. Jfet gates need a path to ground, but that's one of the functions of legs 2 and 1 of the gain potentiometer (the other is providing a voltage divider to set the...

That is a voltage buffer (look for emitter follower or common collector) and it should work, yes

I've never been able to find the schematic for the O2. If it's been traced, I don't think it's been shared. Not sure how willing AMT would be to provide service manuals with factory schematics, but I've seen some online before

Cool, thanks! I'll try to find some good deals on germanium transistors and stock on some low-hfe Si

@Chuck D. Bones, this may be a little off-topic, so feel free to delete this post: have you tried piggybacking transistors (like Q2 and Q3 in here, for example) in place of the germanium transistors in your hybrid germanium-fet designs? I'm having trouble sourcing germanium transistors and those...

I love the blue caps to match the resistors! Where did you source them?

I have built a clone of the Hooke as well, that I really enjoy! One of the things I like about it is it runs on 9V, so no need for charge pumps (I try to avoid them as much as I can). Mine was built on a single sided pcb, with no switching circuit on board
