Here’s a project that I built up some years ago. This never found it’s way into a box. I dug it out and decided to try and box it up. Difficult with the number of switches and knobs. I think I have a viable plan to shoehorn it into a BB sized. box.

This is a pretty interesting distortion box. It’s sort of a Tube Screamer, Rat, Distortion +, with an Octave up. When I finish it up it should be all of those things in one box.

This was built using the layout generously provided by R.G. Keen of GEOFEX fame.

This is an interesting distortion effect with an octave and wah like tone control. I redrew this schem from an issues of Stompboxology.

This is Tim Escobedo‘s Push Me Pull You. It’s an octave up with an interesting design. Using an NPN PNP pair.

Another very original design by Tim Escobedo. This an octave up with a sitar like sound.

This is design by John Hollis. It’s a booster that uses an inductor to generate a massive boost. It also has a switchable octave up. The boost sound is very warm and clear. The octave has a nice tone also.

There is a drop in volume between the octave and the boost, since the octave has to push the signal through a diode ring. This made it impractical to make the octave switchable with a foot switch. Hence the toggle.

I got the 3DPT toggle switches from FutureLec for a very reasonable price. I had to wait weeks for them. FutureLec is slow as mollasses, I would not recommend them if you are in a hurry.

This is a Green Ringer with both the filter mod and nulling mod. I found these mods at General Guitar Gadgets.

The filter mod filters the input signal to bring out a stronger octave. The nulling mod helps tune in the octave generated by balancing the signal on each half of the wave form.

The filter mod is switchable. With the switch on the octave is very pronounced. With an almost cartoonish character.

Here’s a drawing of the scehmatic that combines JC Maillet‘s nulling mod and Ben Milner‘s filter mod.
