Alright, I just sold my old Peavey Ultra Plus and cab in favor of a Dual Rec and Mesa 4x12 Traditional cab. You might remember my thread asking if I can run two heads at once.. well, I've decided that I'm going to take back the Dual Rec since me and the other guitarist in my band have just decided it's not the tone for us. I've narrowed down my choices to the Fireball or the 6505.. the Fireball is slightly more expensive if I buy it from Rocksolidamps, but it's no big deal. Are they similar tone-wise at all? Is one more durable than the other? What are the advantages? And any clips of either head would be really helpful. Thanks guys.
