Okay, so I bought a Peavey Grind NTB, and the previous owner had installed EMG DCs and a two-band preamp to accompany it. However, the bass is wired up with two seperate volume switches, and a stacked bass/treble pot. Which leaves a fourth unused knob. My idea was to rewire the bass as volume, blend, passive tone, (w/ active/passive push/pull) and keep the stacked bass/treble. I went to a local store that is trying to rip off alot of players as of late, (especially new ones [which just disgusts me] ) to get an estimate. The guy said $100 to rewire it all parts included. However, there is a month waiting list. His price turned me off from that shop. So, my question is, what would I need (and maybe a rough estimate) to convert from my setup, to the desired one, whilst doing it myself? Also, if anyone knows where I can buy two EMG style knobs, I greatly appreciate it. Thank you, -Ryan.
