The Berkfinger Studio Spring Reverb

Built for Simon Berckelman

This is another one of the great cases that was sitting around my workspace for years.  For one reason or another it never suited anyone until I convinced Simon that this would be a great case for his spring reverb.  The circuit is the standard Rerun spring reverb with a push-pull driver, high-pass filter on the reverb return, and a separate clean level and tone control.  Because the spring tank sits outside of the control unit it is really easy to try out different springs!
