Why?

From Geartome

All of Yoni Wolf's solo shows supporting Eskimo Snow and subsequent performances are him, a microphone, and a Fender Rhodes into a Roland Micro Cube (which seems to be the choice portable amp for the band; you can also see it here).

Fender Rhodes Mark II Stage 73, Roland JC-120, Ampeg bass amp, Fender Jazz Bass, LP Pro Maracas, Fender Telecaster, various vibraphones/drums.
