What does the amp do well? What doesn't it do well? Is it a great multi-purpose rock amp? I love the tones Grissom gets. Does it need to be at club volumes to sound great? I am on my never ending quest for my ideal amp. I am not tied to any one tone, but definitely stay away from modern metal tones. I love everything from AC/DC, Zep, Gov't Mule, Black Crowes, etc. My RSA23 is very close to perfect. I wish it had a bit more headroom. I love the gain of the RSA23. For reference, I briefly owned a HotCat (ver 1) and didn't care for its gain. It was a bit buzzy to my ears.
