    Overloader! (6 Transistor Big Muff)

    Why these particular transistor choices?

    I'm combining 2 ground planes. Analog and Digital. What potential problems can happen?

    I think it was this video that discussed digital and analogue ground design. At least a couple of his other mixed signal design videos have delved into this too I think

    Equilux Mini (Spaceman Equinox)

    Yup. That EQ curve is magic on guitar, gives you more of what you need, and less of what you don't.

    Where to get components

    It's important to think about ratios in audio though, the difference between 250k and 500k would be quite noticeable, but the difference between 500k and 1M much less so.

    Where to get components

    It looks like a tremolo effect where the LDRs are used to variably shunt signal to ground, I would say the difference between 500k and 1M is likely to be small in this circuit, though will probably affect slightly the perceived maximum "depth" of the effect.

    Where to get components

    Maybe the GL5516 instead then? https://www.pedalpcb.com/product/a2002/ The tricky thing with the photo resistors is that the rise and fall time can also be different, but in a world of vanishing components you have to take what you can get sometimes or pay extortionate prices for NOS stuff.

    Transformers

    The TY-141p may have a worse frequency response on paper, but based on the testing done by some people over at GroupDIY the 141p extends right down to 20hz and up to 20khz without much distortion, as long as you're sensible with the impedance. One person has used it as the input on every...

    Tweed Deluxe pedal???

    Also worth checking out in the "Indiana Tweed Overdrive" a Wampler Tweed in a box.

    EOL parts thread

    It's all pretty much that yeah. Just didn't want to create a new thread.

    EOL parts thread

    Thought this might be the best place for this rather than a new thread. Received an email from Mouser today. Does anyone care about this? Probably be inconsequential from a pedal building perspective, happy to provide the actual links if there is interest.

    1044scpa vs 7662CP vs 7660

    The thread you linked earlier was pretty long. For a non engineer like me, what's the TLDR, are filter caps sufficient or is the ferrite bead and inductor worth an include too?

    1044scpa vs 7662CP vs 7660

    I paid NZ$4.90 ea for a lot of 10 LT1054CP in July, already they are NZ$5.48 for 10. This must be tariffs right? One of the reasons I have switched to LCSC recently.

    1044scpa vs 7662CP vs 7660

    I guess I don't mind spending the extra on parts where it really counts. I'm certainly not out here buying WIMA film caps or Nichi Gold electrolytics or anything like that. But if you're having problems with noise and wine, which really affects the experience of using the pedal, why not just...

    1044scpa vs 7662CP vs 7660

    No one mentioned the LT1054? Seems to solve all these problems. Automatically switches at 25khz. Drop in replacement for the 1044 which is good for designs that already use that.
