The SoCal surf-garage rockers prove an instrument, a pedal, and lots of reverb is all you need to have a raging dance party.

The only bass that Spencer Dunham brought on the road to support the just-released Calico Review is this short-scale ’60s Klira Ohio model that he scored at Caveman Vintage in L.A. The Ohio has a rotary control for its tone filter, but he generally rocks it in the first position. He uses D’Addario ECB82 Chromes Flatwound Medium strings.
