The Twin Lazers K1 is Mr. Black’s true stereo dual phase-shifting modulator pedal. This means two phasers run simultaneously to create crazy wormhole oscillations! Made in Portland, Oregon, USA — Mr. Black are known for their boutique, full-thrust effects that are always musical and inspiring.
Key Features
- True-stereo phase-shifter effect featuring fully isolated left and right channel audio paths.
- Three simple controls: Mix (phase shift mix/level), Shift (phase oscillator 1 & 2 phase lag; 0-180° phase lag between oscillators), and Rate (master oscillator rate).
- Two modes of operation selectable via push-button: Four-Stage (four-stages of phase shift per channel), and Six-Stage (six-stages of phase shift per channel).
- Designed for use in a true-stereo signal chain, or in mono signal chain.
- Double the number of phase shift stages by routing the output of Phaser 1 into input of Phaser 2 and sending output of Phaser 2 to amplifier/rest of mono signal chain, for a total of either 8 or 12 stages of phase shift in series-mono configuration.
- Wide range of oscillator speeds (5Hz – 0.2Hz).
- Optional tap-tempo input with up to 12.5 second (0.08Hz) cycle.
