The Yamaha CSF series takes smaller-size acoustic guitars to a new level. The 600mm scale length, 34mm shorter than a standard full-size acoustic, feels like a regular acoustic, just more comfortable. An all-new bracing pattern lends the CSF3M a rich, full, inspiring tone, the passive Zero Impact pickup provides gig-ready flexibility with natural, dynamic plugged-in tone and the exclusive semi-hard case makes transporting CSF a breeze. Solid Spruce top, solid Mahogany body.
