On a side note, I remembered EffectsLayouts used to offer a preamp like the one you want. It was called the Super Trouper (you could build it to Supergroup of Model T specs) and you can still find the build docs for it (link here). No idea how it sounded, though. It is not very far from a Model...

Adding to Temol and Blackboardcult, I have succesfully adapted the post-tonestack section of the EAE Model Fet for 9V single supply and it sounds quite good

Nice posts as always, Chuck! Any suggested parts/hfe values for q4 and q5?

I can't simulate the circuit right now, but 12k is a little high compared to what we typically see used with j201s. Maybe the original used (borderline) out-of-spec jfets

I'm happy you did, because that CE-1 is absolutely amazing

Temol, do you happen to remember the jfets you used on this one? Would you be willing to share the layout for this one?

Thanks a lot, Chuck! I think I've got it (most of it, anyways)!

Chuck, If the answer to this is short and won't derail this thread, could you tell me why this Idss requirement matters for J201 in muamp circuits, and not for other jfets?

Thanks for sharing this one, Chuck! Everytime I've seen people use a transistor connected to the VCO in order to have small resistances work, it's been a BJT. Any particular reason you've gone for a MOSFET?

+1 Chuck's version is my favorite drive pedal

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
