Based on an iconic vintage circuit, this pedal will adapt to your playing intensity. It plays very well with the low end of the spectrum too, so it sounds incredible on bass. While the original suffered from a serious volume drop when engaged, the Deep Phase is designed to match your level when you kick the switch. With just two knobs and a switch, it offers a wide range of phase tones. 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 shift stages for a smooth effect. The Mode II switch doubles that to 8 stages for twice the number of peaks and a more animated texture. Built into a road-ready MXR mini housing. True hardwire bypass. Cannot be powered by a battery. Powered by 9 volt AC adaptor (ECB003) - not supplied.
