    What difference do Tommy ICs make, and why?

    My (cheap, Aliexpress) multimeter probes are busted - i'll measure when i get a chance :)

    What difference do Tommy ICs make, and why?

    I'm using a normal MXR DC brick - it's not the quietest power supply, but it's workable. I'm wondering if there's something about the circuit where, depending on the IC, if the gain pot is below some threshold the IC doesn't engage. I know very little about EE, but my debugger brain is fixated...

    What difference do Tommy ICs make, and why?

    Something I've noticed with my own Tommy (v2) build: I couldn't find a JRC4559, so I bought a TL072 and a JRC4558 to use instead. The 4558 sounds good but at lower gain settings, the clipping doesn't engage at all. By contrast, using the TL072, with the gain knob barely above 0 it will clip a...

    3pdt breakout: wires keep snapping

    Yep, and I definitely wasn't leaving enough wire to thread through the holes. Once I bought a proper stripper and started leaving ~5mm of slack bare wire, my life got a lot easier.

    3pdt breakout: wires keep snapping

    Just wanted to circle back: per your suggestion I bought a new 3PDT and BB, hooked them up, and not only did the pedal work first time it sounds better than I'd ever hoped. Thank you so much!

    3pdt breakout: wires keep snapping

    Yep! I followed the guide linked earlier in the post and used more generous lengths of wire for those connections. It went much smoother.

    3pdt breakout: wires keep snapping

    I put the heatshrink on thinking it'd help the joints not to snap. Thanks for the guide! I'll do my best to follow it on my next build. Your comment inspired me to pick up a better wire stripper - I'd been using a 20 stripper on my 24 awg wire, and unsurprisingly it wasn't particularly...

    3pdt breakout: wires keep snapping

    I'm not really twisting the wires at all, I don't think. I’ll try the advice of using different-sourced wire and doing as much as possible within the enclosure. I have some solid core wire, if I’m smart about measuring it i think I might use it for these four connections.

    3pdt breakout: wires keep snapping

    I'm using 24awg stranded wire from Tayda. I have this iron, it's 30W. I'm using this solder. The scratches on the PCBs are from my helping hand. I realized kind of late that the metal teeth were scratching up the solder mask, so I put electrical tape on the jaws.

    3pdt breakout: wires keep snapping

    Hi folks! I'm trying to build a Triangulum boost – my first-ever non-kit pedal build – and I'm having a hell of a time connecting the 3pdt breakout board to the main board. I'll successfully solder a few holes but then a wire will just snap, I'll have to clean out the pad, another connection...

    Triangulum boost

    Sorry if this is a naive question, but if R9, R10, D1, D2, and Q2 do nothing, why are they included in the circuit at all? I'm pretty new to electronics, I'm currently building a Triangulum, and I'm a little confused why there'd be redundant components in a circuit.
