4-Stage Analog Phase Shifter with 2 Waveform Internal Modulator
The EMW analog 4-stage Phaser produces one of the deepest and most powerful effects used in electronic music. The analog phase-shifter effect differs a lot from the one created by digital processors mainly because it features a warm and penetrating sound characteristic that is very hard to emulate, This is a must have module for any modular synthesizer setup.
