The SH Spring Reverb from 1968 is a fully transistorised reverb unit for vocals, organ and other instruments. 2 inputs and 2 outputs allow the device to be connected to an amplifier, a tone distortion unit or a Wau-Wau.

The Spring Reverb Unit is fully transistorised with 8 transistors, a 4-stage reverb system for push-pull, power, pick-up and amplifier and a rectifier. It has separate treble and bass controls in the reverb channel. The reverb component can be mixed from 0 to strong with a crossfade control. There is a special connection for the Schaller Bass-Master and GS 1000 devices (source: Schaller).
