The Separate Speaker Cabinets
Our special designed cabinets are tuned for guitar playing and made
fundamentally different than any other commercially available cabi-
nets on the market. We use a lighter weight 5/8” baffle board and
slant it upward on an angle for better projection.
EX112:
A matching cabinet that houses one 12” speaker.
Available unloaded or with our own design Classic Clone 12”
speakers, the CC112/A made in America by Eminence or the
CC112/B made in Britain by Celestion.
EX212:
A matching cabinet that houses two 12” speakers.
Available unloaded or with our own design Classic Clone 12”
speakers, the CC112/A made in America by Eminence or the
CC112/B made in Britain by Celestion.
EX410:
A matching cabinet that houses four 10” speakers, avail-
able unloaded or with our own design Classic Clone 10” speakers
made in Britain by Celestion.
The Custom Color Options
The standard color for GT cabinets is Black Tolex with Tan grill. Various
other colors are available such as Brown, Cream, Red, Purple, Cowboy
Bob Black (the hand tooled look), Ostrich and Boa. Also, special mater-
ial coverings are available on request such as leather and cowhide.

RF1:
A specially made rack fan panel that locates a two speed fan
adjacent to the power tubes which exits the heat from the tubes
thereby prolonging tube life and reliability. Also has 2 extra AC
sockets for Rack effects. Highly recommended for Class A operation
and is included in both the popular Combo Package and Top Package.
SC112:
A combo box with a mounting for a 12” speaker, a rack fan
panel, and room on top of the amp for a single rack FX unit to be
mounted to the amps rack ears via a small piece of rack rail. This
cabinet is designed to hold the Soul-o amp on 4 special rubber
isolators to eliminate interactive microphonic resonances caused
by the speaker at higher playing levels.
NOTE: When you’ve ordered a Combo Package Soul-o amp, we
pack your amp for shipping using two small wood screws into the
side rack mounting rails to stabilize the amp so it will not damage
itself in shipping. You should immediately remove these screws
so the amp can float free on it’s rubber isolators. Also, the power
tubes will be removed and packed in a special material so they will
not become damaged in shipping. Remove these tubes and care-
fully insert them into the tube sockets behind the rack fan panel,
with the GT logos facing outward.
SC112-3:
Same as SC112 but has 2 extra rack spaces above the amp.
SB:
A simple box housing just the amp and a RF.
SB2:
Same as SB but with one rack space above the amp.
