Analog Spring Reverb The VanAmps Sole-Mate analog spring reverb pedal is based on the original Reverbamate circuitry, which has become the reverb standard of choice for the serious guitar player the world over. The Sole-Mate differs from the original Reverbamate in that it has a single output and is fully compatible with any guitar amp on the market today, yesterday or in the future. From surf to jazz and everything in-between, no other reverb comes close. Those who have a one input amp and want the sparkling reverb effect that the original Reverbamate is famous for can now claim that awesome reverb tone for their very own. In addition, the Sole-Mate sports status indicators for power and effect, and comes in a variety of coverings to complement or match just about any amp. The Sole-Mate is a true bypass effect and is fully buffered against loading, meaning you get your true guitar sound unaltered at the output, no rolled off highs or changes in level — just the way you want it.
