so what we have here is simple, im using DIYLC to recreate my schematic so i can modify it.

the pickups are EMG Hz wired to a EMG B30ra Pre-Amp. 1/4" jack is 3 prong so ring can activate Pre-Amp when cord plugged in.

this is my attempt at recreating the circuit itself so i can change things around and acquire extra tone options

i removed the 25k single pot for treble and replaced it with a CTS 500k push pull pot. bottom pot will be wired like normal so it works correctly as a tone control.

the original pickup selector was a EMG Blend Pot i have removed this and changed it out for a 3 way DPDT on/on/on switch.

what i need help with is can on of yaw help me properly recreate the b30ra in diylc? the push pull switch will b used to place all pickups out of phase so i have 6 tone options. i have all 3 pickups working but the b30ra isnt correct or working

Did you make the modifications based on a plan you found somewhere?

Not sure what ICs you're using on the perfboard, but per the schematic they look to be classic single op-amp ICs...except that V+ is usually pin 7 and you have no output connections.

If you've got audio on your TRS jack, you probably shouldn't use it as a DC switch.

im doing a schematic so i can plan and prepare before execution. mostly just need help in diylc putting the emg preamp circuit together. on reverb it has 2 good pictures of the circuit itself but im not electronic circuit smart and dont know what most the parts are and trying to use AI but chatgpt wont help as it would be a violation of its rules so im trying to as certain question to understand the circuit and then remake it in diylc so i can change stuff to see what i need to do from factory setup.

i did remove the pot and replace it already so its just waiting for the shaft up pot to be connected. the blend pot has been removed and a on/on/on installed in its place and thats fine i just need help with the circuitry of the emg b30ra preamp so i can recreate it in diylc. i can make a circuit if its visually drawn i cant understand circuits and symbol schematics so thats what the deal is
