I am actually a guitarist in my band but I played bass in my high school band for 4 years. Recently we decided to by a new bass rig for our bassist who has only been playing for about a year. We bought a Peavey Firebas 700 head and a Hartke 4x10 cab, and we also have a cab with one 15" Eminence Kappa. When I bought the amp and cab I figured that it would have plenty of power to get the job done, but when we play, it always peaks out really bad and the speaker protection light always comes on. Should we invest in a new amp or get something like a power amp? Any suggestions would be greatly appreciated!!
