i would gladly help but i don't have skill's, i'm just guitar player. i could verify/test progress

excellent progress! i'm anxiously waiting this to resolve i have prepared ddt boards but didn't use them because of annoying distortion. maybe it won't be just waisted time money after all

no problem! if you find any improvements be sure to share with us
good luck

r15 is the key as i recall. i put 33k or 39k and it was alot better but not perfect. you need to rebias it after u change r15.
i didn't build or heard 3005 version but cool audio one is not working as it should. it still needs some work to clean those repeats. i build 2 and few friends bulit 4 or 5 and everyone have same problem - DISTORTED REPEATS.

i had just 1 bbd, not 2 as you do.

i built serendipity from your layout and it sounds very good! i used jrc4558 and 1n34a, waiting for ad712 and bat diodes to see is there gonna be any diference.

is there any way to squeeze a little bit more gain and how?

download project file and read it all the way

i built ego driver few times and it's always dark and bassy. i adjusted mine something like you sugested and it's fine now but theres one other thing that's bothering me. no matter what i changed when some other pedal is engaged after egodriver in singal chain i get vol boost and alot of high boost (delay, od, dist, tremolo..). i built several different pcbs and always got the same resoult

is there any difference between v3205d and v3205sd? mine are sd, i ordered from small bear

is regulated, tried subbing every ic, transistors are mpsa18. i will have to check all resistors but i think i got them right.

whitch is the best way to unsolder parts? i tried with vacuum pump and it cant get all solder out

try with battery, i had one and it wouldnt stop humming unless is on battery.

maestro definitely!

and some kind of Tremulus lune with lots of mods would be fun. i have one for 3 years and its one of my favorite builds

9,2v on power supply

1. 0
2. 3,62
3. 3,39
4. 3,4
5. 7,89
6. 3,5
7. 3,55
8. 6,8

i tried playing with R19 and drop voltage to 5v but no change.
feedback resistor R31 also don't effect distortion.
something else is wrong and it's most likely with cool audio v3205 version only. as other people said mn3005 is working just fine.
i poked with probe and delay signal is distorted almost everywhere, one of "cleaner" places is at Q2

tell me where to probe or what to do next, few important places or so? i can even record if it will help.

i bought 8 boards and IC's for all of them, even for ddtime mod. i hope will fix it

boards arrived today and i build one.

everything is working, i calibrated it correctly, only problem is it has too much gain, the repeats are distorted expecially with humbuckers. dry signal is fine.

how to fix that? i found the same problem on freestomp.forum and no answer
