I recently got a 700RB, and like it a lot. I'm considering mating it with a Hartke 115HD and a Hartke 405XL 'mids box', I'll run them bi-amp.
So far I'm using an old Carvin 215 loaded with Eminence 3015s, a 4 ohm cab. It's a smallish, short-throw box and a cool small club system. But I don't think it's ideal... I like the Hartke stuff, we'll see.
I've also got an old 400RB, and use it with the same Carvin cab. I'm still learning about how to EQ/set these. I had an 800 years ago but never did really get it together- my attitude toward gear has changed and I'm taking my time.
The other night I used the 700RB into the Carvin cab. I I ran from the amp's DI to a Hartke Kickback 12 on the guitarist's side of the wide, shallow stage. I also ran from a SansAmp Bass Fly Rig's (basically a VT pre) DI to the pa. The result of going to the little Hartke was a nice monitor for the guitar player that could be eq'd to taste, and given more or less volume. Really tied the band together...
Anyway that's my chime-in. I'm liking my GK heads, still looking for the right cab. I'm open to suggestions, but I've been looking at that newer Hartke 115 and a bi-amp-able top cab (the 405XL). I like the smaller, club/pub-size form of that combo...
