I have an Epiphone Casino Coupe, which sounds wonderful unplugged and plays really well. Unfortunately, plugged in it sounds dull and muddy. I don’t have much experience with fully hollow body guitars, so not sure if that’s just what they tend towards. Or, whether it’s the brass pickup covers, or just crap pickups. anyway, I’m a big fan of p90s. So, I’m really surprised with the sound of this guitar. Not sure whether it’s worth it to try to upgrade the pickups. anyone out there with experience with these guitars?
