These were my 2nd and 3rd builds ever. Chasm uses the Long Belton brick because I wanted it to be nice and spacey. The enclosure lettering is stamped and one of just a few that I used stamps on. It is by far the best stamping I did before abandoning the method because it's extremely difficult to get a good result without ruining the lettering. I've entirely switch to Dymo labels.

The reverb sounds great, especially on my Rhodes. It fills in the space very well without sounding overly effected or distracting like other fancy shimmer reverbs and such.

I want to be able to sweep the phase on the Mutron Phasor 2 like you can on the Biphase. I came up with this simple little circuit add-on which I adapted from the ROG Phozer who adapted it from RG Keen's Univibe mod:

I've only simulated it so far but it seems to work great.
I drew up this modification to the PedalPCB Mutron clone schematic (because it's roomier), but Madbean's Glasshole will modify in the same way.
I did it based on using a 10kb linear expression pedal, with a resistor to taper the pedal into a fake log pot. The log pot seems to be better in this case.
I'm not sure if the diode to ground is actually necessary.

Essentially, the expression pedal just controls the brightness of the LED in the LED/LDR. The switch determines if the phaser sweeps using the LFO or the expression pedal.

The LFO of the Tremulus Lune has a wonderful amount of control over the wave shapes. Can it be used as is for the LFO of an optical phaser, such as the Mutron Phaser 2?

Here's the concept:
Modulation effects take in the Dry input, modulate it to make it fully Wet, and then mix it with the Dry signal at the output to create the Mix output.

My idea is to take the modulation LFO and use it to also be the LFO of a stereo panner, maybe with a knob to control how hard the panning is.
The Dry signal is sent to both stereo outputs in a mono-to-split-mono configuration. The panner sends the fully Wet output to the stereo outputs where it is mixed with the Dry outputs to create the effect of only the Mix signal being smoothly panned back and forth. If it works properly, I think it would be an amazing alternative to the more common stereo Wet-only/Dry-only outputs.

I bought the PCB mostly complete from forum member Brejna and used an MN3007 from Smallbear. It's built into a 1590xx enclosure.

The stereo mod is just a dual buffered output: one in phase, the other flipped phase. It seems a bit richer than just a mono to dual mono, but it's not that dramatic. I was hoping to hear some kind of sweep across the stereo field, almost like the wooshing sound being isolated and panned, but sadly no.

The expression pedal has non-existent documentation on the Lectric-FX build guide, so I had to dredge up the build guide from the Moosapotamus PCB version. The expression pedal lets you freeze the flange and sweep it manually so I absolutely had to include it.
Wiring it up is simple, going from the PCB to a TRS switching jack:
T - tip
S - ring
C - ring switch
sleeve - ground

I think I still need to do a bit of tweeking to get it just right. Doing the frequency counter part was actually the simple part of calibrating it for me. There's a numerical target and you just have to hit it. Doing the remaining parts just by ear is no fun.

I edited the Lectric-FX build doc to include some helpful info and I've included it and the Moosapotamus build doc in this file:
