Built with a four-knob layout with controls for signal mix, tone, decay and predelay which alter the three-way reverb mode switch of hall, shimmer, and modulate, the Lovepedal HSR-3 Multi Reverb takes a reverb triumvirate and turns it into an army of echo possibility. Lush, open, and undulating, the HSR-3 decay and predelay controls allow for big, cavernous sound, long trails, and everything in between for nailing down the perfect tone.
