APH-12 12-Stage Phaser
The Purple Phaze
The Asheville Music Tools Analoger Series APH-12:
100% Analog 12-Stage All-Pass Filter, Dynamic Phaser, Vibrato Pedal
The Analoger™ Series APH-12 is a 100% analog 12-stage phase shifter with deep functionality in a compact footprint. It delivers not only classic phaser tones, but many features and sounds not normally associated with traditional phasers. With a selectable number of all-pass stages from 1 to 12, and our signature control voltage processing, multiple flavors of modulation sit at your fingertips. The APH-12 delivers classic or extreme phase shifting, faux Leslie warble, vibrato and tremolo, vocal envelope followed filter funkiness, and striking multi-peak EQing. Designed by Hawker, this pedal continues the legacy of high stage count phasers and adds some surprises and special features to install Purple pHaze all in your brain.
