Phase / Off Modulation Phaser DIY Pedal Kit

Kit Instructions

Schematic

Controls

The Phase / Off is a four-stage phaser based around the Sound Semiconductor SSI2140 voltage-controlled multi-mode filter. This pedal offers classic phasing effects along with plenty of control to dial in the perfect amount of modulation using the Depth, Rate, and Regen knobs. The Stages switch can change the Phase / Off from four-stage phaser to a two-stage phaser providing a wide variety of different phasing sounds. Change the Mode switch from LFO to Manual to use the Phase / Off in fixed phase mode controlled by the Depth knob for unique filtering effects.

The Phase / Off pedal kit is the second entry in the Nexus Series from Mod® Electronics. This series features a PCB base rather than the Mod® Electronics’ traditional point-to-point wiring kits to offer builders an even wider variety of effects to build. The Phase / Off is a great pedal for intermediate skill sets. It features an all through-hole build with pre-soldered SMT SSI2140.

The pedal operates on 9VDC. A center negative power supply is required for use (not included with kit). There is no battery connection. The pedal draws ~50mA. The enclosure size is a standard 1590BB (4.7" x 3.7" x 1.34").
