This is essentially the AST Head Mk II circuit and chassis placed in a custom pine 1×12 cabinet with top mounted controls like the STR series. And like the AST Head II, the AST Master has a defeatable master volume and can run EL-34 along with the stock 6V6 and 6L6 family. The larger size combo comes stock with the BV-25 but any 12″ can be fitted allowing you to place your favorite 12″ option in this beast (can be custom ordered for a 2×10, too). The AST Master can drive an external cab while running the internal speaker(s) as it has two external outputs with 4/8/16ohm selectable impedance.
