We carry a very comprehensive selection of reverb springs. Be sure to check the part number on your spring before ordering to ensure the highest performance possible. Like speakers, the input and output of a reverb spring have a specific impedance. Using a spring of the incorrect impedance can overload driver or recovery circuits, or cause quiet or no reverb at all. We also offer Belton digital reverb tank replacement in short, medium and long decay. These are ideal for gigging musicians who want the ultimate in reliability.
