AST Master

Bypassable Master Volume - Tube Reverb/Trem

18-20w ~ 6V6/6L6/EL-34 ~ 1x12 or 2x10 Combo

This is essentially the AST Head Mk II circuit and chassis placed in a custom cabinet that can house either a 1x12 or 2x10 driver option, this 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 as well as 2x10 options. So you can place your favorite 12 or 10" pair in this beast. 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.

Compared to the original AST circuit, the AST Master is a slightly hotter result, perhaps not quite as sweet as the AST, but with a bit more edge and a bigger sound due to large cab.

We encourage looking at the speaker options.  Some have even reported loving the Tone Tubby Alnico Hempcone, Extended Highs version.  Please let us or your dealer know your speaker preference.  ALL dealers can put in a custom order to get in queue.  In addition, it can be had in DARK TWEED (see at right)  for $100usd custom charge.  As for early 2011, there was only ONE dark version in World.

This amp had been a custom order piece so is quite rare.   It's now available in limited supply.
