When I was 12 and highly interested in guitars and electronics, I build my own wah wah pedal.
Since then and after my electronics education, I have built and modified several guitar effects for myself and other musicians.
Recently I modified an Arion stereo chorus for Arnold van Dongen (guitarist Ilse de Lange).
I modified it to produce the “Michael Landau” sound.
Of course the “thru bypass” mod is possible for almost any kind of pedal, but I also do mods for boost, overdrive, distortion and other pedals.
Contact me to learn more about the many mod possibilities.
