Backstory: I’m in a cover band with a guy (a friend) who is our keyboard player, but he also plays 2nd guitar on the songs that don’t have keys. His keyboard rig sounds really good, however his guitar rig is really lacking. I’m not trying to be a bigot but his guitar is not cutting it sound wise. He plays an OLD les Paul copy/thrift store guitar. I think it sounds bad more because the electronics/pots/switch are old and cheap. His 3 selecter only selects one pickup and its scratchy and gross. I’ve attempted to swap out his switch before but it’s not like any switch I’ve ever seen (not like a typical les Paul switch and one of those won’t fit in the cavity). Clean sounds.....ok? Passable. Dirty just sounds awful, almost like a blown speaker. I wouldn’t care but he’s for whatever reason oblivious that his stuff sounds not bad, but BROKEN. It makes our band sound bad. What would you do? I feel I need to convince him to take it to a real tech or I even considered donating a Squier strat to him because that would sound 100x better than his rig.
