I had one and liked it, especially for the money. Don't mailorder one, as I had to go through three of them before I got one that was right. If you get one, you will eventually want to upgrade the pickups, and tuners. Overall, it's a very nice guitar, and works great for Blues.
Really cool and often-overlooked guitar. My friend Kenny Greer who plays with Tom Cochrane in Red Rider uses one as his main road guitar, and he's got lots of other nice guitars. Ain't a Hollowbody, but the price sure is right!-Eric
The Epi Kat series is actually made like the CS-336. The back is one carved out piece of mahogany and the center block only goes as far as the bridge, not all the way to the end of the guitar. There's a picture in the Epi plant tour that's on their website that shows a Kat being assembled. You can plainly see inside the carved out back. They're seriously cool.
Bought an Alleykat for my daughter awhile back - great guitar, serious bang for the buck. A local luthier who could get anything he wants just bought himself a Wildcat - equally great. Can't really go wrong for the price or otherwise. I'm surprised at the "heavy" comments - every one I've played has been pretty darned light.
