I just bought a New Jackson Rhoads RRXMG with EMG 85 Neck and EMG 81 Bridge pickups. I am having trouble with the control knobs. In theory I should have one master volume, one neck p/u tone and one bridge p/u tone control. There is no markings indicating what each one controls unlike my fender.
The problem is when I switch to the neck p/u, the knob nearest the neck seems to be the volume, middle nob does nothing and the "tail" knob Slightly tweaks the sound.
When I switch to the bridge p/u, the knob near neck does nothing. The middle knob seems to become the volume,and the tail knob again seems to change tone a little. I would think a master volume knob wouldn't change! The only one that stays the same is the tail knob that only slightly changes sound. How can I figure this thing out?
Bonus question, if I have the switch to Neck pickup, when I turn the knob nearest the neck pickup to adjust "Volume". I have a highly irritating "scrubbing/grinding" sound from the amp. Same when I switch to Bridge P/U. Is that just my setup or something to learn to deal with?
