Currently my guitar has 2 emg 707tws, with the p/p knobs to splitcoil them. Looking to install the emg pa2. Will I be able to run both the p/p from one knob? Can I just take all the wires from one and solder them into the same position on the other so I have the open hole for the pa2?
No, you must have each pickup to its own push-pull pot if you want to coil-split both of them.
