Hi, I am currently using a Gallien Kruger (Sp?) 150 W Combo amp. But I think the speaker is blown on the damn thing and it just isnt loud enough for gigs anyways. Now I dont know much about amps so I need some help. I am short on cash so I was thinking of getting the Behringer Ultrabass BB410 1200W 4x10 Bass Cabinet and the BX4500 Head. Now since I dont know much about Amps I was wondering, if the head and the cab are different wattages what effects does that have? And also does anyone have experience with these products and how do they sound? I am sick of being drowned out by the damn Guitar and Mic'd bass drum at shows. And just sick of this crappy amp for practice as well.
