Commuter Cajon. The Commuter Cajon by Gon Bops is a collapsible instrument that fits smartly into a backpack for transport to rehearsals and sessions. Ideal for urban musicians who commute by bike, public transportation or small vehicle, the Commuter also fits easily into overhead luggage compartments for frequent flyers. Diagonally placed internal guitar strings provide authentic Flamenco tones, while deep resonant chamber offers loud, tight bass. The cajon folds flat and fits nicely into the included backpack gig bag.
