Does anyone have information on these mods? 
I know there is a cap substitution for the regular Phase 90 to get more of a Uni-Vibe
sound and wonder what else may have been done.

"2013-2015 - I built several pedals with different voicings in the phase stages. The "Enterprise Water" or "Aqua Beam" had a smoother phase sweep, but less bottom end.  The "Enterprise Vibe" or "Mojo Beam" had non-uniform phase stages for those who wanted a juicy, chorusy Univibe-esque tone."

Using Patreon Eagle files, which are now available directly from them. I'll be using 1590BB enclosures,
so much of my wiring is offboard. All four are built and working well.

Fiery Red Horse – very high gain Big Muff with charge pump offering voltage cut and boost. It has a
clipping pot and bass/treble Baxandall eq.  It's my favorite BMP variant so far for sludgy metal palm
muting – plenty of gain.


5:00 Fuzz – more traditional Big Muff with voltage starve, clipping switch on both stages and midrange
flat/boost/cut switch. It can go from very smooth, to sputtery


Fuzz Cocktail – modded Fender Blender octave fuzz with more tone and clipping controls.  Unlike the
original, this one has no trouble  reaching unity volume


Wooly Bear – modded Foxx Tone Machine octave fuzz. It has a lot more low end than the original and
cleaner signal can be blended in. The octave is a blend pot, instead of an on/off switch.


Although I used germanium diodes throughout, they suggest schottky diodes as suitable replacements. The
Fiery Red Horse was from Osh Park, and the other 3 pcb's were from Elecrow.

      Here's my Mobius Strip build from the Patreon, same as the one on the main page. I'll be using a 1590BB enclosure, so the pots and jacks are off board. 
      The build went smoothly, but I suggest box film caps for 82n and above.   You can get away with 1/4W resistors, but go for the 1/8W if you can, especially for the ones under the PT2399's.  Like the PDF advises, I had to use rows of in-line sockets, as a 16 pin socket won't fit. 

I don't see it mentioned in the pdf, but swapping the LM308 for an NE5534 gives you the "Glass" version of the Alpha Dog.  This has more head room and less of that classic Rat "squish".  I only did this because I already have a Rat and wanted to try something different.

I didn't use the kit, but a strip board layout, so I don't have the cool clipping pots.  Even with both soft/hard clipping sections wired to on/off/on switches, I'm able to get a wide variety of tones - from  amazingly smooth overdrive to sputtery fuzz.
