After a 15yr. absence, I'm finally getting back into a band!!!! My current dilema I'm going to need a more powerful amp but I'm on a tight budget (wife and 3 kids). I have a Ibanez SDGR SR405 5 string bass w/active EQ and a Crate B-20 amp.The amp is fine in the house or a small garage but I need something bigger and more powerful for practice and gigs(the band has 3 in June already!!) Any advise would be greatly appreciated.$500.00 would be pushing the top of my money envelope.
