Awesome!!!!!!!!!!!!!!!!!!!!!!

By biglow

from Houston

I thought these amps were overpriced and overhyped whenever I'd see them at the music store. I was wrong. I bought the TA501 and was blown away. I got it at a rebate price and since it was like half off I decided I can't go wrong if it's worth double what I'm paying. I use it with the new Hartke Hydrive 4x10 cabinet which is rated at 1000 watts and it's got plenty of power to push this cab. I played and outdoor gig and didn't even have to push it more than half volume. Totally worth the money and the hype.
