I know that David main of D*A*M effects did some bass friendly versions of Tonebender MKII. I don't play bass myself, but my wife does (actually was, but the bass is still around), so I could build it as a xmass gift, contaminate her with fuzz pestilence, and having common topic to talk about again
My understanding is that enlarging input/output caps could give desired result, am I right? I have just scored (thanks Troy) lovely looking 25000pf Iskra brand styroflex caps and I'm hoping it will be the score when rolling bass mk2
Finally, the question - is there any other place to tune except input and output caps when doing bass-able effect version?
