Jordan Vico Vibe Tremolo
Not really a vibrato circuit, but a nice sounding tremolo. This layout is based on the schematic drawn by LucifersTrip on the FSB forum. I've increased the value of the film capacitors from 100n to 220n to reduce the maximum speed a little and make it more usable. People seem to have used anything from 100n to 500n for those caps, so there's room for experimentation there. I also laid it out to utilize onboard pots. It will fit nicely in a 1590B. Just drill the holes for the pots 1.2 inches apart.
