Sorry to resurrect a old thread, but I made a PCB/perf layout with on board pots if anyone is interested.

My layout from the post above is now verified.

Sounds really good. Almost transparent at lower gain settings when pushing a clean amp.

I?ve built this using this layout:
http://tagboardeffects.blogspot.com/201 ... drive.html

sounds good, but when I crank the Treble to max, it acts like as if the circuit is overloading: from overdrive it becomes a fuzzy broken radio sound, which then fades. But as soon as I turn down treble and gain then it works again properly.

Do anybody else experienced this issue?

I'v solved the problem by putting a 150k resistor between lug3 of the Treble pot and the 1nF cap.
Now with all the pots cranked it won't "collapse".
