FEATURES;

• ALL TUBE CIRCUITRY PURE WARM TUBE SOUND – Your guitar signal

does not pass through any transistors or integrated circuits (ICs). We

have also avoided using any relays or other switching devices so nothing

interrupts your pure guitar signal.

• ALL HAND-WIRED CONSTRUCTION – Also sometimes called "point-to-

point" wiring, the A-22 utilizes a very high quality turret board made of

super-tough G10 composite. This glass-epoxy laminate is specified for

its extremely high strength and high dimensional stability over

temperature

absorb moisture and there are no copper traces to peal away from the

board over time. All wiring and soldering is done by hand and quality

checked to ensure many years of trouble free operation.

• CUSTOM-WOUND, AMERICAN-MADE TRANSFORMERS – These

transformers are built to our specifications specifically for the

requirements of this amp design. They are wound on paper bobbins like

in "the good old days" and are rated to withstand extreme heat for high

reliability. In addition, a special type of steel core is utilized for maximum

efficiency, lighter weight and superior tone. The output transformer is

interleaved for optimum balance. Output impedance is switchable to 4, 8

or 16 ohms and 2 speaker jacks are provided.

• CUSTOM DESIGNED CHASSIS – Our chassis is designed specifically for

this amp model so that every part can be mounted in the optimal location

for lowest noise and highest stability.

• CUSTOM DESIGNED CABINET – Our cabinets are specially designed for

maximum durability and superior tone. We use very high-grade void-free

Baltic Birch ply for our cabinets. The cabinet components are precision

cut using high-tech equipment and are hand assembled with care.

Dovetail joints are used at the corners for maximum strength. The combo

cabinet features a 3-piece back that can be configured as closed-back or

semi-open to allow for even more tonal versatility. Unlike most other

combo amps, the speaker compartment is isolated from the tubes. This

greatly reduces the chances of the tubes being vibrated by the sound

pressure waves coming off the back of the speaker therefore reducing

tube microphonics, rattling and premature failure.

• EXTERNAL BIAS TEST POINTS – The A-22 is equipped with external bias

test points and an externally accessible adjustment control. This makes

output tube replacement fast and economical. In fact, with a low cost

multi-meter you can adjust bias yourself. This can be a real advantage in

case of a tube failure during a performance or recording session. See the

section about the rear panel for more information.

The extra-thick board material will never warp, melt, or
