From Old Blood Noise:

Inspired by the unique complexities of running modulations in parallel, Old Blood Noise Endeavors unveils the Visitor Parallel Multi-Modulator. With three different primary modulation options (tremolo, chorus, and phaser) and two parallel secondary modulation options (tremolo and chorus), Visitor immediately inspires new sounds in a single pedal format. Further strangeness occurs with the delay offset of the secondary modulation and the interaction of the secondary rate and the primary depth.

• Primary modulation switchable between tremolo, chorus, and phaser
• Secondary modulation switchable between tremolo and chorus
• Rate and Depth controls for primary modulation
• Secondary knob to simultaneously control depth, rate, and delay offset of secondary modulation
• Regen control for master feedback
• Master mix control
• Expression control over Secondary knob
• Relay bypass switching and standard 9VDC center negative power
