    great advice, i went back just before and soldered a switch onto it and it works. Hopefully now i can wire up the USB-C breakout, to a TP4057 BMS, then to the buck converter. but just before the buck ill put a spst switch there so it will never be more that 4 volts.

    reading a little more, i think i need to swap my double gang linear pot and it sounds like half way on the dial isnt the same as half way on the volume, which i didnt know about.
    Yeah, I think the ones we like to use in audio are 'A' taper, or audio taper pots, which do not increase pass-through the same way, but in a way that our "ears" find more linear.
    Others can explain this better, but you're right, a linear taper pot can go from quiet to loud in an annoyingly small amount of pot travel.
