Here’s an old stuff I made few years ago and kept as it . for now at least , usually I use old unused project to make new one . It saves money . It’s nothing more than a Bajaman tremulator based (to not say “clone”) of the Dementer Tremulador and the Fulltone tremolo (which is the same) . Sounds nice but a bit choppy .
Don’t know what to say about it . I’ll just add that I put an output gain stage with a TL072 to allow a front panel volume pot. The gain boost isn’t massive , just X5 I think. The big “rate” knob can be manipulated with foot .
