my treble pickup is quieter and i cant get it to go loud, i tried it on two amps and the same thing happened i just got it yesterday and it was working fine this morning!!

Try raising it. I had the same problem with my Epi Les Paul.

Quieter, as in a sudden loss of volume and performance, or it's just not loud and obnoxious?

If the latter, try raising it. If the former, check the wiring.

something is probably wrong with the wiring. i have the exact same problem with my g-400 but it's the bridge pickup. it does suck
