Here is my Si Tonebender built on Jimmy's excellent PCB. I believe he plans to do a run of these in the near future...
This is an improved MKII design from Mictester over at FSB. It is really an optimized MKII with a simple tone control and output buffer. There is also an input capacitor switch to put in a big (10uf) cap for added awesomeness. My build uses BC108 and BC109 transistors. This is a Rustoleum hammertone finish with mini chickenheads. I used a Tayda 1590b which has really steep sides (almost zero draft angle) and Tayda pcb mount jacks which stick out really far.
This thing sounds awesome. Great sustain on high gain settings. Low gain is more of a unique benderish overdrive. Very happy with the volume knob roll off of this circuit, not completely clean but nice useable drive that doesn't dull out. You can pull great regular MKII tones out of it too. Overall a very versatile effect, I could see it covering the area of several other circuits.


First takes

. The guitar goes slightly out of tune toward the end (new strings), sorry!
