Someone made a tighter layout for this on the tagboardeffects forum. Just noticed it, I figured it should be posted here too: http://guitar-fx-layouts.42897.x6.nabbl ... .html#none

Some observations of a slightly more pedantic nature (which will require absolutely no PCB rework): - swap the placement of R7 and D1 (which will increase RF/noise immunity towards power supply lines) - solder a smal mini-melf SMT 15-18V 0.5W zener across the opamp pin 3 and 4 on the PCB trace-side...

Hey, I made a very layout for the buffer - still unverified. You need a track cut between pins 1 and 8 of the IC. Pin 1 is the output offset pin, which is not used, and pin 8 is NC - No Connection. Wo I hadn't checked this thread until now. Will try adding a track cut and see what happens. That sai...

Verified. You weren't kidding, this buffer is stupidly awesome! The much simpler Tl071 buffer I was previously using was quite obviously coloring my tone. With your circuit there is barely any audible difference between plugging straight into my amp and running the signal through the buffer, my enti...

Hey, I made a very layout for the buffer - still unverified. Will let you guys know if it works upon building it. Also, I'm sure there's a way of making the layout more compact and elegant, but this is one of my first - apologies for that.

Yup, that's the one! I will obviously breadboard this before even thinking about boxing it up, but roughly, the idea is to set up a loop send at the node that goes into IC1A 3, and a return at the node that precedes R8. (Or you could just put your favorite self-oscillating and/or gated fuzz circuit ...

Has anyone tried using the envelope generator side of this with gated fuzz and self-oscillating fuzz?
