AST Master
Bypassable Master Volume - Tube Reverb/Trem
18-22w ~ 6V6/6L6 ~ 1x12 w/Speaker options
Or Run Internal AND External Cab together!



This is essentially the AST Head Mk II circuit and chassis placed in a custom pine 1x12 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 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 2x10, too, though we prefer the 12). The AST Master can drive an external cab while running the internal speaker 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 a smidgeno less sweet as the AST, but with a bit more edge and a bigger sound due to large cab.  It sounds quite large and expansive and has become a favorite of many Swart fans. 

We encourage looking at the speaker options.  Some have even reported loving the Tone Tubby Alnico Hempcone, Extended Highs version among others.  The Anniversary is the most sensitive of the bunch and probably the best at cutting through in a band situation.  The Gold is also a favorite with great tone when pushed.  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.
