Alright. Here's the deal. I recently stumbled apon a used Peavey 2x15 Cab powered by an SWR 2002 200 watt amp. For 400 dollars. Killer deal, no? Tried it out, works great. Went to dad. Got the same argument as always. "Why can't you just play through the school's PA system?" followed by "how do you think big artists play huge stadiums?" Good question. I've been thinking about it for a while, and haven't found a reasonable answer. Bottom line: I'd like someone with a reasonable amount of experience to explain to me why PA is not the only way to go and why the bassist needs an amp too. Thanks in advance. James A few EDITS: -I own a Crate BT-25 practice amp. -I know nothing about my school's PA -Another reason for my dad shooting down the idea is that the amp is up to my chest, pretty big, and since he's never had anything around the house like this he's hesitant. I could move some old toys and a stereo to the attic, and there'd be more than enough room.
