Re: Dead Tone knob?
Figure it this way, did you at all touch the tone pot when you removed your old pickups and installed your new pickups? If you did make sure that one side of the tone pot is still properly grounded and that the connection between the volume pot and the tone pot is good.
However, before you go nuts trying to figure out this problem. You should really ask yourself on how much you actually use the tone pot. If you don't really touch it at all (as in it's on full blast all the time), you should just consider removing it from the circuit entirely so reduce the amount of resistance in the circuit. By ditching your tone you do get a brighter(more presence) and a wee more output. In fact some companies(*cough* ESP Japan*cough*) actually put a switch that wires your bridge pickup right to your output jack for the maximum 'in your face' tone by eliminating the complete circuitry in the guitar. (ok, that may be going too far but you get the point).
