This 1966 Ampeg SB-12 is a flip-top amp with a single 12-inch speaker. These amps are known to deliver warm, round, and rich tube saturation at lower volumes, making it a favorite for studio recording and small-to-medium gigs. The SB-12 was originally designed to complement the Ampeg Baby Bass upright bass, though popular for electric bass and guitar as well. A beautiful vintage piece for any collector or studio.
