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
