Preamp losing volume across circuit

I have the 10k volume pot disconnected, but right before the 0.002uf capacitor above it I’m getting the full thick signal but right after the capacitor when I signal trace I get a volume drop and then after every other component I get a slight volume drop until the output where it’s very quiet.

Question about adding gain stage to rat

Just quickly while I’m away from my desk or computer to test this out, but I’m looking into designing a rat style pedal and want to add multiple gain stages to it before clipping and the tone section. Would this be something that I can do? Or will this cause issues with output and input impedance? Thanks in advance for any responses!

Demo of my envelope-controlled low octave pedal

I'll have to do another video that goes into more depth, but this is what I have so far. I'd actually use it as-is right now, but I may trim (pun intended) down on the number of exposed pots and smooth out the sound a bit. Think I may experiment with higher value capacitors and decouple a few more components.

Is there a sub like this one but for amplifiers?

Just curious. Thanks in advance!

Why does this Tube Screamer circuit have an extra 100 nF capacitor?

Source: https://barbarach.com/tube-screamer-on-a-breadboard/

C12 is a 100 nF capacitor between +9V and ground. It's parallel with C10, raising the total capacitance to 100.1 µF.

I haven't seen this capacitor in other schematics. What's its use?

You can make a charge pump from inverter gates (no, seriously)

Hi everyone, I’d like to put my build on a breadboard before soldering and I’m struggling to find a schematic for this build.

I’m also very very new to this and am striving to take this hobby more seriously in the near future, so any advice would be greatly appreciated! Thanks everyone!

what value pot should i use for the “intensity” control on the memphis compressor?

hi, hoping this is okay to post on this category. if not can you please guide me in the right direction?

i have a vintage Memphis Compressor pedal i need to fix. it’s missing the Intensity potentiometer.

any insight into how i may know what value pot i need? or does anyone know a general value i can use? i can’t seem to find a schematic here is a photo of what i am working with. the other potentiometer is a volume pot.

thank you

Help with capacitor values in Hotone Harmony

I goofed. I'm trying to convert a Hotone Harmony to a eurorack module. An SMD capacitor fell off and I can't find it anywhere. It was between two legs of the "wet" pot. There was a matching one between the same two legs of the "dry" pot, so I tried to remove it to measure it, and I also lost it. Any ideas of what these values might be, or what to try first? I wasn't able to find a schematic anywhere, but they're C13 and C14.

LM368 board into PT2399

After building an LM386 overdrive and a PT2399 delay from cheap boards from China last week I wanted to try putting the LM386 straight into the PT2399 instead of a buffer. The result is a crazy glitchy noise maker.
