Used - JHS Tank

A whole spring reverb tank, about as big as a wallet. Well, not a real spring reverb tank, but you won't be able to tell the difference. The JHS Spring Reverb Tank offers infinitely tweak-able, amp-style spring reverb in a simple, straight-forward design, and the built-in effects loop allows you to add effects to the reverb tail for a totally customizable sound.
