I have been playing an SWR 550X with a Henry 8X8 for quite some time. Absolutely love the tone of this amp. It does get a little aggravating moving that cab in / out of various venues. I recently purchased the KB15 due to the ease of moving it around and usage in smaller clubs. But after trying it out a couple of times, I'm thinking it could move to the #1 slot. 500W peak, every tone I could possibly ask for with the 3 band EQ and shape function, can be used as a monitor with the kickback design, and 35lbs! The HyDrive gives me the warm paper tone, as well as the high end clarity. Needless to say, I'm super happy with this amp.
