Mr. Black DeluxePlus Reverb & Tremolo

 Spring reverb and bias-modulating tremolo in one small box.

• Use each effect individually or together for the true vintage vibe.

• Waaayyy more drippy reverb available than your amp can deliver.

• Deep, buttery-smooth tremolo that dips n dives like a unicorn-dolphin should.

• True-bypass

• 9VDC power (2.1mm negative center pin adapter) or internal 9V battery
