Controllable Tremolo Circuit

This is a design circuit for guitar effect. This circuit is a simple design and it is built by FET. This is the figure of the circuit.

This tremolo circuit is not a "plug and play" ready guitar effect, however it could be converted to one switching. with the relative ease. It just needs some buffering on the input and output and perhaps some bypass. This circuit is powered using 18 V DC.


  1. 18V is an inconvenient voltage

  2. The circuit is very old; the polarity of the supply is reversed, and with the values shown won’t oscillate , I do not know where you obtained this design but it would be best you take it off your website and check the original data before you put it back, it doesn’t work
