Would anyone be interested in my mods on my Big Muff ? Hm, I don't really care, I like to share what I'm doing, especially when it's working ! So, the subject is my russian muff. I allready add a boss type DC input. I switched for a blue led, as Fozzy did (I really LOVE that mod !! ), and I'm curently working on THE big mod : adding a // dry loop right inside the box (and True bypass mod of course, but that's the easy part). Indeed, you all noticed that the muff used alone eat all your attack and bass. For me, it is simply unusable like this. I use my Boss LS-2 to add a // dry loop, but I want to free the LS-2 for other purposes. And as an electrical engineering student, I wanted to work on real projects, because theory is good, but I realized soon that it's nothing when it comes to reality... So, the facts. Here is my current schematic : The caps are 0.1 mF. It works, but I don't know if it will be the final schematic. I have to make tests on my amp. Here is what my bed looked like 1 hour ago... I think I will finish this next week. I'll let you know, and if someone is interested, I can give all the infos. It would work with any pedal. Feel free to ask any question or make any remark ! I'm really happy, my first real electronic project is working !
