Want vintage phase tones but don't have the pedalboard real estate? The MXR Deep Phase is the solution. Standing on the shoulders of the iconic Phase 90, the Deep Phase offers the same impeccable quality with increased tweakability. Based on an iconic vintage circuit that delivers crystal clear sound with a pronounced swoosh, scooped mids, and a dynamic, voice-like response to your attack, Deep Phase adds a feedback control and a dual-mode option. It also plays very well with the low end of the spectrum, making it a great choice for bass players. The Speed knob adjusts the effect rate, while the FDBK knob adjusts the intensity and sharpness of the phase peaks. By default, the pedal runs on 4 phase shifter stages for a smooth effect, but the Mode II switch doubles that to 8 stages for twice the number of peaks and a more animated texture. And since it's MXR, you know it's road-tested tough. Go ahead.
