Spring Tank

The JHS Spring Tank is a spring-style reverb pedal designed to reproduce amp-style spring reverb with two independently adjustable reverb mix levels. Depth controls the perceived room size, Length adjusts reverb decay, and Highs adds or removes high frequencies from the reverb. Tank 1 sets the primary reverb mix, while Tank 2 provides a secondary mix level that can be activated with its dedicated footswitch. Boost adjusts the overall output to compensate for perceived volume loss. The pedal also includes an effects loop that allows external effects to process only the reverb tails. An internal switch configures the loop to remain active continuously or operate only when Tank 2 is engaged.
