I am very proud of how this modded Rat (NO DUH) came out. Some value changes and a Filth control that blends between LED and Asymetric Si clipping. There is a lot of texture to play with here since the LEDs are never symmetrical unless all the way counter clockwise. I specifically wanted to...

I want to put a dpdt switch into a pedal with a soft switch. It only needs to he engaged while pushed in. The relays i bought are for 4.5v but only engage with 5v. Go figure. So I stole 5v from the L7805>run to momentary switch>positive of coil. Also an led I may include but it's not needed...

I have a project in the works that needs a dpdt momentary switch. Its so hard to find one that doesn't have a very hard press so I would like to go soft touch. I saw this and would just rather build my own into my layout. https://mas-effects.com/digital-relay-switch.pdf Im curious too now if...

There is a mostly complete report on this over in the mods section but here are the bullet points. The art is taken off a beer from There Does Not Exist. Art by @ibayarifins. Great beer, Great art. Mode switch changed to pot Octave blend added to remove octave completely at full ccw Bigger...

Great sounding pedal. My 10 year old populated and soldered about 90% of this. Graphic is a drawing into Ai and then photoshop.

This is where my hyper fuzz is so far. I'm particularly interested in knowing if I can improve upon the octave blend. It works well though so maybe against all odds i did good. Gain changed to A250k for MORE GAIN. The Boost is skipped over so Scooped and Full can be wired to a B50k blend pot...

Made one a long time ago and never connected with it. Recently I though it would be fun to take a swing at some redesign. Changes are circled in blue. C9,R20,C13 help nudge the sound towards a more usable verb without losing too much of the dba style. Feedback surge footswitch because its fun...

Im not sure this is the right category for this so I can move it if need be. Why so many voltage dividers biasing the op amps? R4,5 12,13 18,19 Couldn't i just put one pair with a capacitor to create 4v5/vb and run from there?

OK, this got started over in the mods thread but im moving it over here. As chords and notes decay I hear a lot of fizzle. I'm using an op07cp from Texas Instruments. I have tried lm308. I'm thinking they are real because they came from Jameco, reputable place. Honestly I've tried every op amp...

I just populated this thing and starting playing. Holy lord, how much bass can a circuit have?! I tried some different values at C28 but im sure there is a smarter way. I fear i have to knock down ALL the 10u and 22u caps. Has anyone dove into modding this to a more reasonable bass range?

Mo(not)onous Delay This was a fun project to delve into. I certainly didn’t stay true to the short delay, tape warble aesthetic. The delay still does that sound but now it can run wild too. Very versatile now for rockabilly, dub, shoegaze etc. Delay time is extended and feedback added to...

does anyone have the build doc on this older layout? I'm looking to do some mods but would love to avoid taking the whole thing apart. Thanks in advance.

I recently built a hudson broadcast and love it. I'm looking to find other transistor only drives to try. No opamps wanted. The only other one i can think of off the top of my head is the smallsound/bigsound mini. Of course that one is jfet versus the broadcasts bjt's. Any suggestions?

Just rabidly ordered the pastel preamp pcb. But now I'm looking around and don't see where to buy the 2N6429's. Is there an equivalent transistor?

I recently built the Elysium Ambient Delay/EM5 Echo Machine. My only issue is the delay control (b50k) makes a static-y noise if it's parked at 12oclock. A little turn either direction and it goes away. I tried replacing the pot and putting some electrical tape under it but it persists. Any...

Would you be so kind as to tell me what my target voltages are for the figment 5457's? Thanks

Just wired this up and JUST WOW! Thanks for this. My only question is what's the third tone control? Bottom is the rat. Middle is the muff. What the heck is the up position? Crazy cool but whaaaattt?! Also is the schematic available so I can understand the filters better? Thanks

Just built a parentheses Mini and I love it. I perf boarded a rotary switch to still have the extra germanium option like the larger version. Only mod I made. However the volume knob I notice is really inconsistent on the different modes. The distortion knob really does far more for volume. Is...
