I would put a hipshot Ric replacement bridge on that bass. It would make palm muting and intonation a LOT easier.
Also it is good you put the pickups in assymetrically to favor the E string. This is a good trick to get better low E volume on the Ric bass.
Re the Hipshot, I'm considering it. My action is absurdly low. With the hipshot (which I had on an otherwise stock JG 4001C64), when you get the saddles that low, the down-pressure decreases and you encounter that infamous saddle-wobble issue. If I do end up adding that bridge to this bass, I will mod it to allow string-thru and add holes and ferrules to the bass. Running the strings thru the body would increase the angle the strings cut at the saddle from the spec 20 degrees to more like 90. This "should' eliminate the wobble and make that bridge a viable option for me.
We'll see.
