Based on the classic Phase 45 phaser pedal, this PCB offers a quick and easy way to add some classic modulation to your guitar tone.
Using easy-to-source components and sized perfectly for a standard 1590B enclosure, everything is board mounted – even the rate potentiometer, flashing rate LED and bias trimpot.
As well as the standard Phase 45 circuit, this board has been adjusted to include an on-board bias trimmer and a flashing LED tied directly to the speed of the phaser sweep.
Please note: These PCBs are reduced due to minor production issues – the printed leg numbers for the potentiometer are incorrect and some of the capacitor spacings are a little tight. Neither of these issues affects the board and full details are provided in the build instructions document.
When you buy this PCB you will also get:
- The PCB itself
- Bill of materials (BOM)
- Build instructions document
If you want a head-start on this build, why not grab a Phase 45 component kit (including matched transistors) from Bitsbox here – you’ll just need to get an extra 2.4k resistor and an LED for the flashing rate indicator!
