I finished this up a couple months ago and realized I never posted it to my blog. This is a circuit layout from David Rolo who hangs out over at Madbean Forums. This tremolo can go from a standard harmonic tremolo to a syncopated chopped up rhythm machine.
Here is so more info taken from David’s site:
4 Tremolo modes:
- Black Face (regular volume modulation)
- Brown Face (modulation between bass and treble, like the Harmonic Vibrato in old Fender Brown Face amps)
- Bass modulation only, with fix treble
- Treble modulation only, with fix bass
8 different wave shapes provided by the powerful TAPLFO chip:
Sawtooth, Reversed Sawtooth, Square, Triangle, Sine, Lump, Reverse Lump, Random
Rate, Division, Tone, Depth, Shape, Shape distortion & Tap Tempo
I programmed my own TAPLFO pic for this project.
(For some reason I could not get my iPhone to take a photo with the right white balance with this red paint. Hence the ugly green color in the first photo)
Looks like for the last picture I need to align that switch so it doesn’t ground out on the enclosure. lol
