Ah! I was hoping someone with experience would offer comments on this, thanks.
Yes, I used an Explorer, I have a number of different guitars although my favorites are my two explorers (Gibsons), one with EMG 81-85 pickups and the other with EMG 81-60s, as well as a couple of ESP-EXs, an Epiphone Goth Explorer with EMG 81-60s, and a basic Ibanez with a ZW EMG 81-85 set switched around (the 85 in the bridge and 60 in the neck).
I also have two cheap electric bass guitars, 4-string Yamaha and 5-string Rouge-II.
Regarding the bass guitar track, it actually is in the mix, although I admit it isn't well defined as I know very little by comparison about mixing bass guitar tracks. I did however use a low cut on the main guitar tracks to leave room for the bass around ~85 Hz.
A real amp, especially a powerful tube amp, is simply out of the question, simply because:
1) I'm in a high-rise apartment building, I have to stick to equipment that doesn't make too much noise, in particular FIR speaker impulses (I use the keFIR VST plug-in) and headphones,
2) I'm in an old apartment building, including the electrical wiring, which wouldn't handle something like what you're talking about, and finally,
3) Real tube amps, good ones, do cost a bit of money that I don't have right now, not to mention the cost of attenuating the output or some type of load for the amp while running it in place of a cabinet that I couldn't use anyhow because of the noise that would get me evicted from my apartment.
I do have a solid state amp I could try though, it has the jacks for FX loop and everything and that might work better, Ibanez ToneBlaster amp-head TB150-something-or-other that I forget and can't recall the exact name of at the moment.
I also have other Guitar Amp emulation software packages, NI Guitar Rig 3.2.1 and Line 6, I could try those.
Yes, I've played with real Marshall Tube amps, I like them, I've heard them, but they aren't a real option for my apartment.
Before I started using keFIR I was using both an AxeTrak and a Grendel Dead Room (Iso-Cab).
Edit: I've also got an Art Tube Pre-Amp (real tube inside) that I can use with other stuff.
