    How does this tone control work?

    I'd like to try to modify this, what components should I be looking at?

    DOD FX10

    I really like this one. I think it was called a preamp when it came out. It's replaced my micro amp + in my rig

    Darlington transistors exist...do Sziklai pair transistors exist?

    Are they called something else?

    Two Aleph Null builds

    Moka Pot and Clever Hans. Haven't played enough with the Moka but I can already tell the Clever Hans is gonna be a new favorite for me. Build one! Thanks @Aleph Null ! Oh one thing, I couldn't fit the 1N5817 I had in the holes very easily so I just omitted them

    Executive fuzz and polarity

    Am I correct in thinking this schematic will invert the polarity of the signal?

    A Simple Big Muff

    After seeing some new components in the shop I decided to make this. It has some features I've been wanting to try: -No sustain pot, just straight through -C50K tone pot -Resistor arrays for maximum build speed -Russian npn transistors paired with germanium pnp to form Sziklai pairs in the...

    Voltage divider issue

    I have the following schematic and voltages....I was under the impression that the 10K resistors form a voltage divider and VCC should therefore be ~4.5V, am I wrong?

    Dream Fuzz - more gain?

    Is there a simple way to squeeze more gain out of this thing? https://www.pedalpcb.com/product/dreamfuzz/

    Dynamic jfet overdrive

    Here is a bastardized version of a smallsound bigsound F*** overdrive. I stole most of this from @marksescon (thank you) https://www.marksescon.com/blog/2023/7/20/kintsugi It's working quite well. I'm not sure it's 100% matching the original (the fornicus project has an additional jfet on the...

    Is there such a thing as a DPDT dip switch?

    For reasons I won't go in to, I'm wondering if this part exists? I have a footprint for a DPDT switch but I'd like it to be internal, is there an easy way to achieve this? Thanks

    MOSFET Pie

    Modified from the available MOSFET Pie 2 schematic and modified for BS250s because someone on the internet said they were quieter than BS170 and everything on the internet is true so I had to try it. This one is cool, it doesn't have the woofiness of a regular big muff. Nice on bass it would...

    Fuzzduster (JFET Big Muff content)

    I stumbled upon @jubal81 's Fuzzduster and knew I had to build it. Then I decided I wanted a big box for it and and then I decided to use 24mm pots. Execution could have been better bit hey. Ended up with 2n5457 in Q1 and Q4 and j201 in Q2 and Q3. I subbed the diodes for LEDs. Only played it a...

    MOSFETs, N to P channel

    Hi all, I'm trying to replace some N-channel BS170 MOSFETs for P-channel BS250s and something's not going right. I'm wondering if this zener could be my issue, does it need to reverse directions? I've read that it's static protection. I'm trying to build this circuit...

    Hissing noise goes away when pad is touched

    I built a circuit which works, but has a pretty large amount of white noise in the background. I've found that touching the circled pad with anything makes it go away. What could this be a symptom of, or what could be a remedy? I don't really understand how me holding a resistor with tweezers...

    Tape saturator diode compressor

    Adapted from DIYRE's color module and this site: Link I need to do some recording or reamping to get a full sense of this thing but at first glance I like it. I might just use it on everything, it seems pretty clean when set low on the soft setting.

    The Creamery Compressor & noise

    I love this compressor. It feels the best to play for what I do. The only issue I have with it is that it's a little bit noisy (at least my build is). Noisy as in a faint white noise type of sound, regardless of the guitar signal. Is there anything we can do to attempt to mitigate this...

    Crap-fi Delay

    Wow this thing is noisy. At first it sounded like something was broken until I realized the repeats knob is backwards. I think this will be nice in my vocal chain Gerbers available if anyone needs boards. I don't remember who I got this schematic from but thank you

    Mic pre FX loop

    Here is Rev 2 of my looper box. This includes a THAT mic pre in front. Upon first firing this didn't work but after digging more on the diyaudio forum I found someone doing the same project as this one, and doing it in an easier way so I may make my way to a rev 3 with more features

    regarding powering multiple parts of a circuit

    As an ongoing work on my XLR looper, I'd like to include a preamp inside which requires +48V power. Let's say the rest of the circuit requires +/- 12V, and I'd also like to include a pedal effect which would take +12V. Is the diagram I've drawn below feasible? Is 48 to 12 V too much of a...

    XLR looper box

    This is a box that takes a balanced line level input from my preamp and let's me send it to pedals and back to the computer I have some more ideas for a future iteration such as including a preamp inside and others
