These days, Smith and Gallup are Schecter endorsers, so they use their "artist" models ( electric 6, acoustics, Bass VI, and bass guitar) for the shows, other than when they do the bit where they play three entire albums; for those they seem to mostly use the same instruments used back in the day, or models of same make at least. I believe I noticed RS using a couple Roland Jazz Chorus amps when they were playing "All Cats Are Grey" from what I believe were the "Reflections" series of shows (first three albums) it's ytube and of course Simons P Bass sounds particularly good (Amped backline, not Peavey as I think they were on Peavey amps then)
