I would suggest saving up for more 4x12's. Never know when you'll need that extra "push over the cliff".

Personally I would save your money and buy other stuff you may need - I own the same amp and find it to be pretty versatile. You could [if you also sing] upgrade your PA, buy some nice mics for your home studio and or live situations, or even start a recording rig if you havent already.

One thing I do with extra cash is mod stuff... if you're handy it can be fun.

If the tonal variations are wide enough, a multiple amp setup is always cool. Get a splitter and a a/b/y switch and switch between the amps as needed. Joe Bonamassa has a great multi-amp setup wuth usually 2 Marshall Jubilee's, a Two-Rock and lately a Dumble or a Fuchs. He switches amps like guys use pedals. Great tones though.

Dude, you must be rich and famous with rodies to lug all that gear around for you!

im 18, and have a nice job while i go to college. i wouldnt call myself rich, but big purchases are well within reach. as for roadies, i transport all my own stuff in my honda accord, if i ever need teh extra cabinet, i have my drummer move it.

Also, I don't know where you're playing at that acommodates that size rig. That's gotta be loud and hell to mix out front.
I play anywhere from 500 to 5,000 seat venues. Sometimes some huge outdoor festivals and concerts...50,000 being the largest. I've never had more than a 50watt amp onstage. My current Fuchs rig consists of a 50w ODS head and a 2x12 cab. The Master's on 3 and is more than loud enough.

gear is overated. tone is in the fingers. as for volume,any decent venue will mic up you cab(s) and can give just about any amp a pretty mostrous sound. i've known ppl who simply plug a POD into the main board for all their sounds. no cabs even needed. but it is nice to have that sound behind you. bottom line is that the more cabs you bring, the harder it will be for the soundman to put you in the mix. less is more. unless you are playing huge rooms,all those cabs will usually be overkill for most clubs. and you really do want to be in the mix if ya can. obviously it all depends on the room you are playing and the type of gig it is. if it's a heavy metal gig to a decent sized room,then maybe bring both cabs, but 90% of the time you'll only need or want to have one cab. if i were you, i would look into some nice pedals and a good pedalboard. for a thousand bucks you can put together a really nice effect system or sure..........

again try them side by side......
