About this amp

AST Master houses the AST Head Mk II’s circuit and chassis in a larger 1x12 pine cabinet with top-mounted controls. It keeps the defeatable master volume and 6V6/6L6 flexibility of the head version, and its two outputs with 4/8/16 ohm selectable impedance let it drive an external cab alongside the internal speaker.
