the bass section isn't as full featured as it could be in gr4. tube emulations are sorely lacking. but if you have computer enough to run it live (requires a fast computer and plenty of ram plus a switcher), it's fantastic for guitar. in this case, though, it's overkill.I am a big fan of Native Instruments` Guitar Rig software. It even has the option of selecting a mic, placement angle, and distance / air from cab. Not to mention all of the various effects, cabs, heads and combos. GR 4 is out now, and I`ve heard it has an expanded bass section, as well.
