Hey all, I'm about to buy a head for my Avatar 4x10, and I'm having trouble deciding which to buy. I'm debating between the Ampeg B2R and the Warwick Pro Fet IV. Now, the Ampeg goes up to 350 watts at $550, and the Warwick at 400 watts at $560...I'm going for a rock sound (Ampeg) yet I hear the Warwick's a little more versatile with its EQ. So anyone with experience of either and/or both of these, please tell me which you think would be the best head to go with. Thanks!
