This is treble booster from the Stompboxology. This was an interesting new letter published by Nicolas Boscorelli. Who has, it seems, disappeared. If anyone has any information about this guy please email me! I looking for issues of Stompboxology. I have a few I can trade. There are some posted at http://moosapotamus.net/.
He also published The Stombox Cookbook. Which is very cool. It contains a lot of original and interesting Stompbox designs.
It has an interesting and original design based around a pair of FET’s.
Here’s the schematic that I redrew from the Stomboxology article.
Here’s a layout that I drew.
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.
