I have to admit, when I'm practicing at home, I love the tone I get from my HA3500 head. The tone I get is perfectly suited to the style I play and the overall group sound. I also love the tone I get from the Kickback 12. I just wish I could get the same tone on stage. The signal is nice an clean at low volumes, but it breaks up when I have to crank. I have the limiter open to keep it from cutting. It still breaks up on me in the 3rd set when the drummer really gets banging and everyone has slowly pushed the individual volumes up. I may get a power amp and use the HA3500 as my pre. Is this a viable solution? Does the power amp have a big impact on tone? Will it be OK until I can get a good preamp?
