The Mr. Black Twin Lasers is a stereo phase-shifter/modulator pedal featuring two independent phaser engines that can run in stereo or series mono to create rich, swirling modulation effects. It offers selectable four-stage or six-stage modes, intuitive controls like Mix, Shift, and Rate, expression pedal and tap/exp input assignability, and a preset save/recall feature. The pedal draws under ~70 mA from a standard 9 V DC negative-center power supply and is handmade with a durable enclosure.
