hi guys need your help with something else. i was thinking of buying a B2r head and i guess firstly do you guys think it would be loud enough for a 5 pce band, thatd play pubs, clubs small venues etc? and anyway should i consider getting the head new or used? i thought at first that i should get the head new and the cab used. but it retails for about $1999aussie while i can get it used on ebay for less than half that. so what do you guys think? also iv bought heaps of stuff off ebay before but none of them musical, think its a good idea to get it without trying? and one last question would an AMPEG SVT 2X15 BASS CABINET be too loud? i dont know anything about these but was getting a good price on one. so b2r n svt good deal? thanks heaps!
