The Swart AST Atomic Space Tone Master (also known as the AST Mk II Combo), is essentially the AST Head Mk II circuit and chassis in a combo form with top mounted controls like the Space Tone Reverb (STR) amps.

It features a defeatable master volume and can use EL34's (as well as the stock 6V6 and 6L6's).  Standard, it can come with the BV-25 speaker, but more common is the Celestion Anniversary or the Celestion Alnico Gold.  

The AST Master can also drive an external cab while running the internal speaker(s) as it has two external outputs with 4/8/16ohm selectable impedance.

The AST Master is a bit hotter than the original AST design with a bit more edge and a bigger sound due to the larger cab enclosure for the speaker.
