okay right now i use an Ampeg BA115, it does alright for what i do, but i feel underpowered alot. Well before i go any further, i play weekly at our church, every wednesday night for the senior high, and sundays for the main service. Im usually good for the senior high room, but in the auditorium i need more. So, i 99% sure i want a 4x10, then maybe down the road throw a 1x15 under it. But i need some reccomondations on a cab and amp. Keep in mind though, that im a junior in highscool = small budget. I played the GK 410 GLX at guitar center and really liked it, would that be an okay setup paired with the backline 600? the total for those two was $600 i think, i could probably get it down to at least $500. What are some other good setups around that price range, or a little more, that pack a punch??
