Hello, I was wondering if anyone is familiar with Hartke amps and can give me a comparison between the Kickbacks and the new "B" series - pros and cons of each... For example, a local store has one of each model for the same price of $339. The Kickback is the smallest in the Kickback series - 120 Watts and a 10" aluminum speaker. They also have a B90, which is 90 watts with a larger cabinet and speaker. Both have the nice Shape button and dial, which give a variety of tones. I can get either for $339. I'd probably be using the amp for nothing more than jamming with some others in a recording studio... thanks!!!
