Duo-Phase kit

It sound so good, really good project, its like the mutron bi-phase but in this wiring diagram the phasor B goes into the phasor A, so if you want the original mutron phasor order you have to wire the first input Jack mono to phasor A-input than switch Jack output A into phasor B-input Jack

Very good toned phaser and fairly easy to build. only the holes in the leds were in a slightly wrong place in my opinion.

A close to perfect kit. The PCB is compact - perfect for fitting in the box and making a small pedal. I followed my own advice and double checked everything while building (took 4-5 hours total approximately, spread over a few evenings). Pedal worked right from the start. A wonderful thing to have this replica of an _extremely_ rare phaser pedal. The sound was wonderful! :D

Heres my Instagram post of the finished thing: https://www.instagram.com/p/CeG_L0WDyuf/ (with sound)
And heres a link to Pedalspcb with more details: https://forum.pedalpcb.com/threads/duo-phase-build-panel-layout-and-lfo-mod-question.11906/
In the PedalPcb I included my front and side layouts too.

More details on trimming, comments on colors of LEDs would be on the wishlist for possible updated information on the pedal - but the kit itself is a clear 5-star kit.


Comment, on a more general note on building complex machines: there are a lot of components and I would suggest great care when mounting them all. Think like this: Resoldering _is_ possible - but it will take 10 x time. At least. So measure everything. Double check everything. Use sockets!

Addition: I recommend using shielded wire from the inputs to the switches, it only needs to be grounded in one end. When I did this I had no problems at all. More details in the Forum-thread above.

Build it carefully and you will have a fantastic pedal at the fraction of the cost!
