Just gonna post my notes instead of listing everything out Was curious to see how it'd sound if I replaced all the gyrator values with those from the Boss HM-2 where applicable. I like the results. Things heavy and noisy as ass straight from heck. Though it doesn't do the same sorta buzzsaw as...

Minimal mods to this one, but here goes C1, C3, C5, and C9 are all 27n R3 is 2.2k (didn't feel like digging for 2k) R4 and R9 are omitted C4 and C6 are 100p C7 is 2.2u D1 and D2 are Red and IR LEDs respectively C8 is 4.7n C11 is 560n R13 is 470R Dirt (Slam) is 1MD D4 is a Red LED C16 is 4.7n...

Another Percolator borrowing the values from @Aleph Null's Peacock Dirt (Harmonics) is 100kD with a 4.7k stopper resistor on Lug 1 to ground C2 is 47n C3 is 2.2u C4 is 22uf C6 is 2.2u R1 is 470k R2 is 150k R4 is 33k Diodes are a KD221A and Red LED Transistors are 2N5087 and 2N7000 Squidward...

Decided to start off my stack of Double Muffin boards with a couple circuits not included in the regular Muffin build doc - the Hizumitas (Shika) and Fuzz War (Bellum mkii) Building the Shika side was easy, but adapting the Bellum to the board required a couple small hacks (the shrink-tubed...

Had someone commission this Octarock, but they wanted the Ringer and Bass Only switches from the Mu-Tron Octave Divider. The upper octave and dry signal are left stock, while I tweaked the lower octave to be more inline with most The applicable mods found here. I'll do a more detailed...

Another Rat, because that's all I know how to do. Built on a pair of DirtMonger MultiRat boards, and housed in. Deucetone-style enclosure. Brutalist knobs, cuz duh. Soft touch mini DPDT footswitches The right-hand side features a Soviet UD1408A, which is a slightly darker, less gainy take on...

Only deviations form the build doc are R12/R13 which I've replaced with 12k and 22k, respectively. This was done to bring the volume of the dirt channel closer to that of the clean, while avoiding oversaturating the buffer preceding the filter. Rebiasing that buffer could probably gain a bit...

@MichaelW wanted to know my thoughts as he recently built one, and was also less than impressed, so here's this little rundown. Built to the doc except for the clipping diodes- I replaced one of the silicon clippers on the Rhythm side with an IR LED, and replaced both clipper on the Lead side...

Moonn's AluTonez (SHO pushing a LofoMofo) and Mean Queen (Bastard Muff fuzz Klon mashup) running parallel. I wasn't particularly impressed with either circuit on their own, so I figured I'd mess with em in parallel. Together they sound pretty awesome in a filthily scuzztastic way. They both have...

I don't care for the modulation provided by this, but the full mids superfuzz variant it houses is rad, though it does lack some output volume stock Mostly stock, mods being - R9 reduced to 1k for better octave matching, and attached to an spdt to kill the octave R17 increased to 270k for more...

Yet Another Analog Delay Only components that differ from the doc is R45- I went with 24k, and I used an NE571 FX loop is inserted between Lug 2 of the FDBK pot and the board BLST shorts lug 2 & 3 of the FDBK pot, and puts a 10k in parallel with R45 Spent about an hour troubleshooting this...

I didn't have any 2n3392, so I grabbed the first transistors I found in my stash with the same pin out. Those happened to be 2SC1815s. R4 & R8 reduced to 270r to push the input and output a hair more. 1.5k added between lug 1 of the Sens pot so it doesn't bottom out Big, nasty, clangy. Build it

Built to the doc, except I replaced the diodes in the envelope detector portion with BAT46, reduced the Sens / Sweep pot to 5k w/ 4.6k from lug 1 to ground, and added a 50kB in parallel with R34 & R35. This effects the response of one of the formant filters, and is highly interactive with the...

Built to the doc, a except I added a 1MA pot in series with R23, and an on/off/on switch tied to lugs 1&3 of said gain pot. The throws select between a pair 1N41418, and a mismatched white led / 1N4148. I increased C3 & C4 to 22n as suggested in the doc. Master volume trimpot made external. Ton...

Someone hit me up about possibly building an OD-1 so he could get a bit more mids to cut through the writhing sonic mass of his bassist and drummer. Being me, I had to suggest the Rat. He said he'd planned on grabbing one of those too, and so I says to him, I says, "fuck it, we're getting two...

Built to the doc, except R7 which is reduced to 470r for more lower gain range, and R18 which is 18k because I didn't feel like digging out a 20k This is a pretty rad take on the transistor Big Muff topology. Gets rid of the clipping diodes and third stage filtering, and has had the tone stack...

Outside of the fine tuner and increased speed capacitor for the LFO, and omitting the diode for the LED, this one's built to the doc Distortion is courtesy of one of my Rats. At some point I plug in an expression pedal Housed in an NOS Bud Box CU-234, and labeled with a Posca pen This...

Built mostly to the doc (Turbo spec), with the changes being - Opamp swapped to TL070 Comp cap is 39p High pole cap is 2.7u Low pole resistor is 470r Clippers are square red LEDs Tone pot is decreased to 50kA, resistor preceding it increased to 2.7k, cap decreased to 2.7n Distortion pot is...

Another commission, this time from a bassist wanting something filthy, funky, and classic (And, I used an actual bass for this demo. Though, I did screw up and recorded with my Twin sim instead of the SVT I setup specifically for this demo 😅) The Ocelot board is the most tweaked, as the goal...

Built mostly stock - a few components on the echo side I had to use the closest value I had on hand, turned the dark/ bright switch on the reverb into a 100k pot, and the added Feedblast footswitches. Think I might need to replace the blast pot for the reverb, it's range seems screwed up...
