I bought a used SRX500 yesterday and I have a couple questions. It has passive pickups with an active eq, so on my Ampeg BA115 to I plug into the passive jack or -15db jack ? What is the stock string gauge? I have Rotosound 66's 45-105 on my GSR200. It is black but what is the color code? I has an aftermarket output jack on it and I would like to get an original. The original part number is 3JK1C14DZ but I don't know where to order it from. The straplock that was on there got ripped out(on the bottom) but instead of putting a new one in the some hole the previous owner but a new one in about an inch away to theres a tiny hole in the body. It didn't seem to affect the ballance of it and my new strap covers it up but I would like to fix it. Does anyone know what a good filler/epoxy is that I can put in there and I would love to find some matching black paint. Also what is the production run of the SRX500? My serial number is C01110885 so I am assuming it was built in 2001 but they were not made in 2001 so I guess its a early 2002 model?
