Dunham plugs the Ohio into this 1970s Ampeg SR4 Sound Reinforcement Mixer that is actually designed (and originally used by the band) as a PA. Spencer digs the head’s versatility (four inputs/channels), its crystal clean tone, and the fact that it has onboard reverb for days. The head runs through a 1990s Ampeg cabinet that houses a 10” and a 15” speaker.

Shop Scott's Rig







Zach loves his Sovtek Mig 60 head, which he plays through a cab he built himself at a pipe-organ shop in Denver. Every glue joint is lined with thin leather for maximum air tightness, and it’s stocked with Celestion G12M Greenback speakers.
