Usually I bring my pedalboard, amp, two guitars to a gig. My pedalboard has a Boston eq, Boston noise gate, Jekyll and hyde v2, Sansamp british character series, Boss Fender twin reverb modeller, Digitech rp55 and Shure pgx14 wireless.
My "barebones" setup (usually pag sobrang rush) doesn't involve a pedalboard, I just use my Squier Telecustom I, cable and Laney Lx65r. Sometimes if MASSIVE (lulz) rush I'll just use the venue's amp. I use the neck pickup for cleans then the bridge for dirt.
It doesn't count as a barebones pedalboard setup but it's literally a barebones setup though. Hahaha
