Tube spring reverb with tremolo and vibrato

Built for Anders Olsen

Taken from the ashes of a Heathkit Harmonic Distortion Meter, this unit is a tube spring reverb unit with dwell, tone and output controls and a switchable tube tremolo and vibrato circuit adapted from M. Blencowe with speed, depth and output controls.  The dual inputs/outputs allow the user to separate the effects for use in effect ways or even a stereo amplifier.  The large VU meter displays the amount of signal that reaches the spring while the green lamp flashes in time to the tremolo/vibrato.  As well, the external power supply allows for less noise which makes the unit perfect for the studio and the stage.
