I replaced C4 with a 10U and it cured the overly brightness

I built one of the blackhatboojum AD9 pcb's and love it. warm with a touch softer repeats than other analog delays I've built biased mine at 550ms.

Great pedal!

Q1 4.6V Q2 5.2V Q3 4.2 Q4 4.6V I built this pedal hoping to get some Soundgarden Superunknowm sounds, after fidding with the bias and controls I've found some settings that nail Spoonman and a few other songs. Someone somewhere suggested 2n5457's, happy I used them. This pedal is a bit...

I just finished the pedalpcb Boogie Monster version, PL uses 100K for all 4 trimpots. My Q4 goes from 2.6v to 9V.

Skoolie! It's on my list.

I have an Anamorph. I could put a fx loop in it. I think I'll put this in the project wish list.

I just built one, highly recommend. Mine is biased at 650ms. I 've tinkered with it up to 810ms but it's a bit wonky that high up. If you want a smaller box madbean has the skoolie board in stock atm.

Are there any delay 's with rng modulation? I was playing around with a delay into my low tide and thought about this.

Try gently wiggling the socketed transistors one at a time, I've had issues with them not being soldered.

I want one!

Reminds me Parasit Studio has a modulation Mod board with a pot for rate and a trim pot depth that could be replaced with 2 wires and an offboard pot. https://parasitstudio.com/shop/Modboard-daughterboard-p752039729 If you look at the build doc this would be easy to add between pt2399 pin6 and...

+1 The Skoolie has a charge pump (15V), input pot and wiggles, and its in stock ATM.

If it works, it WORKS!

Fired up first try after biasing! I think building it over a few months helped. Costly circuit to toss in the fix it later drawer

Dimensional Chorus based on DimensionP Chorus, gerber courtesy of dan.schumaker, and Madbean Florist. Love the bloom circuit on the florist.

Really like how clean the build and wire forms are. I think my next build I'll try forming the wiring like that.

Done! Bought the board in july, been slowly buying parts here n there. Special thank you to Audandash for figuring out the enclosure specs for Tayda Drilling. My 5th Analog delay build. It's Clean for an analog delay, unless you dime the input and then the repeats sound like a mild overdive...

Fantastic Circuit!

Late to the party... IC4 is a low frequency oscillator (LFO) that creates a small low frequency ac waveform that feeds the 4047, then the 4047 turns the ac waveform into a squarewave that is used as the clock or timing signal to run the bbd chip. (If you don't know how a bbd works electrosmash...
