The no diode options it's amazing, simply tube-like boost. It's not clean, but has a little less distortion than the MOSFETS.However, without the diodes the volume output goes up dramatically, necessitating twiddling with the volume to keep from blowing your ears out.I had some trouble in building this effect, in fact, I build two prototypes, because the first one became unuseable.I used TI's LM308N opamp, and Fairchild's 2N5458 Mosfet. After a lot of debugging I discovered that wiring the pots to the PC board (about 2 inches long) caused a lot of oscillation, noises and malfunction, just like having bad contact from hell! Soldering the pots straight to the PC board was the better way to avoid that.Enclosure was cast aluminium blind electrical box from Tramontina.Check out some pics here: again, FP and TONEPAD."LA RATA" is my second TONEPAD project build, the first one being the Distortion .It has a distinctive treble boost distortion that cuts through a cluttered band sound.
AND BIG PLUS: I took out the 30p F cap, my chip LM308AN just simply sounds better, with shiny harmonics and dynamics on pick! I tried several diode modes even the open one but I still preffered the original, symetrical clipping using 914's..the ways, this is not a thin sounding distortion, sound is very very thick "quality" indeed that could go chug a chug specially when cascaded with an EQ. If you preferred a lighter distortion then go for the TS808, I'm sure this will suit your needs. I used the LM208 metal can op amp (I found it in a local store).
It seems a bit odd to say that a distortion is smooth, but this thing is.
