Recreating the classic sounds of a spring reverb unit, the Palmer Vintage Reverb provides extensive control. Decay lets you dial in reverb length from a subtle bounce to cavernous tails, a tone selector adds natural warmth or splashy brightness, and mix blends in the effect with the dry signal. The compact pedal features a heavy-duty footswitch and runs on a 9V battery or optional power adapter, e.g. Palmer PW9V.
