Everyone here seems to be doing pretty well with their builds and wanted to throw my hat into the successful build ring again. This time, I finished a Duo-Phase with zero issues when done. I thought I had a problem at first when one of the LEDs stopped throbbing. But it turned out the battery I was using to test it with was aged and not up to par for this mondo build. Once I used a regulated 9v wall wart, everything behaved as it should. Woot!
Building this particular circuit bears a significance for me as one of my very first guitar pedals was a genuine Mutron Bi-Phase that I got in trade for an amp repair back in the 80's. I remember my heart breaking when I sold it years later.
I haven't gotten to the enclosure finishing stage yet, but have the artwork done in Photoshop and worked up a 2-D mockup of the completed Duo-Phase pedal. While the Photoshop mockup shows the LEDs externally, I've decided to not bezel-mount them and will leave them subterranean beneath the decal with a 3mm hole in the enclosure to let the light thru in a nice diffused glow rather than piercing bright laser beams into the eyes.
The rest of the images are photos of the pre-decayed pedal, gutshot and some of the build process stages.
I considered sanding the clear surface of the LEDs to add some diffusion, but I also know that at such close proximity, it wouldn't really make a discernible difference. The finished circuit sounds great with the water-clear yellow LEDs.
The finished gutshot demonstrates how close the tolerances of the physical dimensions of the PCB and hardware are.
This is going to replace the two other 6-stage phasers I currently have on my pedalboard - a Krypton Phaser (Mutron Phase II circuit) and an Ibanez PH-7 Phaser. They both sound great, but the Duo-Phase adds a bit more dimension by being able to synch the two phase circuits to a single LFO.
This has been one of my more satisfying PedalPCB builds yet. Thanks for looking.
