So, now that I'm no longer in Terrorhorse, I'm selling off my bass rig to build a new uber-rig. I love the sound I get with my bass rig, but I'm not likely to be a full-time bassist again anytime soon.
The idea I've come up with is to create a rig that will work for both guitar and bass so that I can use it for any gig I may get.
Basically, I'm going to build a rack-based system, that will include a modeller of some sort, and a poweramp of some sort, and then have a guitar cab and a bass cab, and I can just bring whichever cab is needed for the gig. I already know the modeller will either by a POD X3 Pro or an Axe-FX depending on budget, I just need to decide on a poweramp and a guitar cab (I'm thinking something in a 2x12), and I might swap out my bass cab for a 2x10.
1) Can anyone comment on the quality of the Ampeg model in the Axe-FX? I'm an Ampeg user anyways, so I won't mind only having the one bass amp model if it's got that Ampeg sound.
2) What power amps would be good for both guitar and bass (preferably stereo, in case I decide to use both guitar/bass at the same gig)?
If you can't get a good Ampeg sound from your guitar processor, buy a Tech 21 Sansamp VT Bass for $130 and run it into either a big tube or solid-state power amp.
If you want tubes, you're going to want a hefty power section for your bass side; something like the discontinued Mesa Strategy 295 or 400 series might work, while a 20/20 is plenty for your guitar side. You will also notice a significant weight difference between the sides if you go this route; I'd almost recommend having a separate rack for your power amps in that regard.
Otherwise, a popular choice is the Carvin DCM2000L. 15 lbs, $480 USD, 2000W @ 4 ohms bridged, or 600W/side at 4 ohms.

Now, your POD X3 will sound great with a tube power amp. My stepdad uses his X3 Live through the FX loop return of a Vox AC50CC2 combo and it sounds very, very good. Bass just needs grunt, whether it be 300W tube or twice that in SS, although if you plan on gigging areas with PAs you can pretty much go direct and use a small poweramp/cab for stage monitoring.
The bass will sound better with a tube power amp, but that's a significant cost and weight increase, and running my VT Bass into a QSC SS power amp sounds quite good regardless.
