I posted a "demo" of this song back in 2015, but I recently re-recorded and/or remixed everything to produce this "upgraded" version:
Guitars and bass are all done with Amplitube 4. Actually, since I've now got some TRackS5 plugins, some of those are in the mix as well (though mostly on the vocal or mix-bus chains).
Rhythm guitars are mostly OR120 amp models (with matching cabs) and the "Big Pig" stomp model. The little lead guitar bits are ... mmm, I think a dual-amp Soldano+Marshall amp model thing, with the Fulltone SSTE rack model used in a stomp position for the delays.
The bass is (as so often in mixes) processed in multiple tracks. There is a heavily compressed clean DI (no Amplitube there) for the low end; a track with the Ampeg SVT-VR models for mids/highs throughout; and (just in the middle "bridge" section, which has a kind of bass solo-y part) another track run through the JH Gold for more presence in the mids/highs.
