Re: Best $400 -$450 Bass Amp
Go with a cab for a few hundred. Go used. You can get a SWR, Trace Elliot or Hartke for that sort of money.
As for a head, hunt around for a GK 800RB, or a Peavey Mark IV. If the 800RB's are too pricey then look for the 400RB's. They're good for most but the older 800's are legendary.
Stay away from Behringer. Don't buy new....
