I’ve been building this tremolo for years, I think it sounds really great. I found it in the Stompboxology News letter, which I bought around 2000! I’m in the process of learning Kicad, I wanted to learn how to make some PCBs with SMD components and have them fabricated. This became a good subject for that project.
This is my take the Stomboxology Tremolo XXII. This has an all transistor signal path. The modulator has a Square and Triangle switch and a shape knobs that sets the pulse width of the Square wave, or morphs from Saw to Triangle to Ramp.
This first build worked but the Depth and Rate knobs rotate backwards. Who’s to say what backwards is in these things, maybe its for left handed people? It does feel backwards. Have to switch it up in a future revision. It did work and sounded great.
I finished this off with some of these Mini Chicken Head knobs.
