    The GSR has the Phat-2 EQ circuit. Anyone ever wire this up? I've got 'em in there and not a sound is to be heard.

    I haven't wired one up but the GSR uses passive pickups. For an upgrade I'd replace with compatible passive pickups.

    I kept the APJ-1's and just bypassed the stock Phat EQ board. They sound great! Now I believe the bass is worth more than it's worth. But I read their wiring diagram upside-down and so the volumes were back ward, I had to turn it up to turn it down. And tone was backwards, treble was really bass. So I re-did it ONE MORE TIME! But by now the pots are scratchy. :( :( :(. I hope the spray cleaner works, other wise it back to ground floor and getting new 100k audi pots and doing it all over again. I Yi Yi Yi YI.

    PS: anyone ever wire them up with TWO batteries (18v)?

    Ultimately I went with the 9-volt.= battery. The Phat-2 does NOT work with the APJ-1 pickups. After a lot of fussing around I eventually ruined the supplied pots and had to order new ones. I wired as the diagram from the web site and all is well. Battery life is a problem (I keep plugged in for long periods.) And since they tried to set them up at the same level as passive pickups voicing is somewhat week. So even though they are active pickups I need to plug them into the hi-gain input of the amp. Otherwise the sound is excellent!!!! They make my entry level GSR-200 sound like a more expensive bassman or something. I use those smooth flat-wound strings. It gives a jass-like sound in combo with the modern voicing of the APJ-1 and it's a really great sound for all kinds of music. Adjust the EQ to suit and it can handle many different styles. I don't use an effects box or a floor box. Oops, actually I do use an OC-3 sometimes, but very suble settings. Our guitars use effects box but not excessively. We play stage amps exclusively. No line-in to mixers. That's just not guitar to me. Keyboard Motif to mixer is OK though.

    Doesn't the GSR 200 have a P-J set up? Did you mod it for 2 Js or did you just replace the bridge J?

    I'm just a bit confused as you mention only the J pickup.

    Sorry. I just re-read your post and realized that you did buy a P-J set. I apologize for being so dense.
