Hello guys, I recently bought a Schecter Syn Custom-S. It seems to have a problem though. When I switch to the bridge pickup using the pickup switch, it sometimes starts giving a very low gain output, but the other pickups work fine. When I switch the sustainiac on from the neck or middle position, there's no problem, however if I switch it on from the bridge position, it gives the same low gain output. Anyone know where the problem could be? I can't really go get it checked right now because of the quarantine stuff, so any advice is useful.
