I had a guy repair my guitar a while back. He claimed the pickups were all wired funny and that he re-wired them to what he claimed was "normal". Well now my guitar sounds like absolute crap. He owns a guitar repair shop but there is no way in hell I'm going back to him. I am good with electronics and soldering and thought I would do it myself. My problem is finding a wiring diagram for my guitar. Can anyone help me out?

Re: RT650GFR

you could try going to the dimarzio website and check out their wiring diagrams there. just choose one of their pickups go under installation and click on the file and open.

Re: RT650GFR

Your tech may have presumed the 8-lug switch adhered to the normal 8-lug pattern, but those old Iby switches definitely did not -- the terminals have altogether different internal connections and functions as compared to a traditional switch. If you're still using the original switch, then many of the online wiring diagrams will be misleading.

Having said that, a few years ago, I rewired my RT650 for a pickup swap and kept some very cryptic notes about the original wiring. For all of this, I name the switch terminals as 1 to 8, looking down at the switch above the electonics cavity. I have no idea what the "correct" way to name/number the terminals is, but that's how I did it. As may be obvious, I am hopeless when it comes to understanding what everything does, but hopefully this will be of some use. Good luck!

Neck pickup: red to terminal #3
white to #8
green and bare to ground on Volume pot

Middle pickup: red to #2
white to ground on volume pot

Bridge pickup: red to #1
white to #6
ground to volume pot (I presume 2 pickup wires were soldered together for the ground, but I didn't note what color(s) those were)

Terminal #4 of switch had a white wire from the left lug of the volume pot
Terminal #5 of switch had a white wire from the tone pot

One more note: I have a couple of "unmolested" RT650s, so if nothing above helps you out, I can probably have a look inside one of those to see what's up.

Re: RT650GFR

duuude...the EXACT same thing happened to me several years ago with one of my rt450s. my typically competent luthier was putting in a tone zone/paf pro combo into this guitar and completely mis-wired it based on typical stratocaster 5 way switching. my guitar sounded like absolute horsesh*t. i finally found a luthier who realized what was going on and he rewired it the way it was supposed to go.

then one day on jemsite, someone posted the wiring scheme for the rt450 (be aware, the 450 is practically the same guitar; the only differences are cosmetic). luckily, i have saved this and i am more than happy to share it with you. let me put it up on imageshack and i'll post it in this thread
