Two of the caps' values aren't listened. One's 0.001, the other 0.01. I assumed uf but I'm not too sure.
And about the gain pot... I assume it's linear right?

Also...Is there anyway to wire it up so that I can use a 2PDT switch? 3DPTs can't be found around here and I can't order anything over the net. Putting a mains adaptor is easy but without a 3PDTs I'd have to renounce to the LED...and I kinda want it. So does a SIMPLE buffer using common parts exist for it?

Thanks :)

yes and yes.

millenium bypass will let you use a dpdt switch with an LED. i would avoid electronic switching on such a small circuit. incidentally, the buffer has nothing to do with the LED. the switch does. what you are likely referring to is the way boss and other commercial pedals do their switching. they actually engage the effect only when the flip-flop jfet switching is on, and a ground connection made by a momentary switch tells the fets to turn on or off. as i understand it, this also creates a buffer, but just building a simple buffer has nothing to do with switching unless you do it this way. on such a simple circuit, the parts count can't be justified for a fet switch, so i would suggest the milennium bypass. hope all that made sense...  :icon_biggrin:

Yeah that's what I meant. Makes sense it's not the best way though... I'll research this millenium switching :) Thanks!

Ok either I'm a total spaz or I'm blind, but a search and look through the forums turned up nothing :s
