Guitar model - Epiphone Les Paul Custom
Pickups - Stock epiphone h'bucker.
Year - 1998.
Problem - Very bad/ loud / piercing feedback at high volume/gain.
I've put copper shielding tape in the pickup cavities
and on the back of the cover plates (then ran out of tape). The problem is still there.
Q - Is there an easy fix for this or do I need to change the pickups and/or wiring loom ? I don't mind paying up for new pickups if that's the only way to fix it as the guitar landed cheap (£155).
Cheers in advance,
