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...

Essentially applied the mods From this build, using @Aleph Null's Peacock value for most of the swaps The box is a custom sparkly matte black from Missouri Electrical Box Company I throw in some Rat stackage toward the end

Except for the clipping diodes, this is built stock. I opted for a mismatched blue and orange for the hard clippers to get a lil asymmetry and more volume. I also replace the lone 1N914 in the feedback loop with two antiparallel orange LEDs, with a switch to engage each separately. The one...

Not much to say about this, other than it's full of amazing sounds and loud as fuuuu... This was a commission for someone wanting a modified take on the DBA Thee Ffuzz Warr Overload. He wanted the boost to be louder and bigger, and the Aft was perfect for the job. I used a Tesla KFY46 with an...

I built this for a friend's birthday gift. He's incredibly fond of the @Aleph Null Peacock I'd given him, but had brought up wanting a standalone version of the Percolator from that circuit, and has always loved the Atomizer graphics, so here's this guy Mods are (resistor values taken from the...

Just a few tweaks Hard clippers are red LEDs, with R11 being reduced to 47r to hit them harder C8 is 470n and R9 is 270k to fatten the soft clipping stage a bit C18 is 22n and C19 is 1n to approximate the frequency with the parts I have on hand. Shifts the high band down a smidge C16 is 33n...

Didn't change a whole lot, but here's my tweaks C2 to 27n cuz I've been liking that number lately 🤷🏻 R6 is now 100r to phatten up the Distortion side and give it more of a Rat-ty snarl C5 is 2.7u for further phat R7 is 1k R8 is 1k to have a bit more low gain range Clippers are infrared LEDs C8...

Been on a parallel dirt box kick, and someone happened to request on of these, but wanted it louder with a bit more range, so here's what I did Mods - All caps in signal path increased from 22n to 47n Fuzz transistors are 2N4123 (Q1 hfe 87, Q2 hfe 74) C8 reduced to 22n R2 reduced to 1k R13...

Stock except the diodes (infrared, 1.1vf), dirt pot (100kA), and obviously added the bits for two channel. Eddystone 1590J box, Brutalist knobs, white ink Its simple, it's heavy, it's EQ control spans from flat n middy to scoops. Doesn't do clean boost, but it does awesome distortion through...

Built mostly stock, the only mods being - R5 is 100r to saturate the chip a teensy bit more C12 is 27p to accommodate the chip swap Chip is an LM308 from Polida (fake? 🤷🏻 sounds good, either way) Drive is increased to 100k Toggle switch added to swap the stock silicon's for red LEDs or no...

This was originally just going to be a Turbo Rat featuring the Soviet UD1408 and glass LEDs, but I had to make some further adjustments to compensate for how dark the chip turned out to be. You'll notice the chip is upside down- I bought a couple dozen of these from a guy in Ukraine, and...
