I have an Ashdown 100 watt that was cranked during practice and it died. I am going to use the combo as a cab and sit a head on top of the 15inch enclosure. I am looking to buy a new head in the area of 300 watts. I think it should be enough. I am having trouble trying to decide on which to buy. Ashdown MAG 300H 300W Bass Amp Head Gallien & Krueger Backline 600 Bass Head Behringer 450-Watt Bass Amp Head BX4500H Behringer BVT4500H 450W Bass Amp Head W/Modeling + ($250.00)??? Hartke 2500 Bass Guitar Amplifier Head 250 watts Ampeg B1RE 300W Solid State Bass Head Factory B-Stock These all seem like viable options but I have no way of testing to see what I like. GCs bass section sucks. I value your opinions.
