MXR Phase 45 clone

Looks great. Bet it sounds great too. Good luck with the clear..should be okay if you start with a light mist and then build up from there. Just go easy at first.

Thanks, I will try that.

I got the rest of the wiring done tonight, and some testing:


It works, but I don't know if it sounds like it should since I have never played a real Phase 45 pedal and I have substituted the op amps and transistors. The op amps shouldn't matter but the transistors could well change the sound. After dialing in the trimpot, I get most of the phasing effect in the last 20% of the rate knob. At the highest setting it has more of a vibrato feel. Sounds good, but more vibrato than phasing. Backing the knob off full by even a tiny bit and it's back in phaser territory.

So it works well enough to box, and I can try the original spec transistors when they arrive. I could also try my other 2 matched J201s.

One minor hiccup: I got so carried away with the MDF jig to hold the jacks in place for soldering that I forgot the DC jack is threaded on the inside, so it needs to be soldered into the enclosure. I had to cut the wires and will fix when I box in a day or so.
