Had a chance to play with an 1001RB II this past weekend. I really liked the tone it had but was underwhelmed by the cab used (Ampeg 810). Price and size issues alone make it a no no for me. There are a lot of threads here about the various offerings from GK but I was hoping for a more conscise breakdown of what each cabinet line has to offer. From what I gather the SBX is the "budget" line, the RBXs are the top shelf cabs, and the Neos offer lighter weight and apparently a more characteristic sound. Whats the real deal on these and what would be a good pairing with the 1001RB?
