The Blue Moon is a purist's dream come true. The entire signal path is
designed to deliver an unusually smooth tube sound, from clean - to clean
plus even harmonics - to a thick liquid lead tone - to a full-on scream.
To hear audio clips, check below.
Every stage of the amp, including the preamp stages, and the
power stage, are triode, single-ended. This delivers the highest possible
even-harmonic content you'll hear from a guitar amplifier.
In the early preamp stages, we make use of a few techniques that help drive the
signal with less noise. That calls for an additional preamp tube being used, but
the object here is to get the highest-quality tone possible.
The cathode-biased, single-ended, true class-A power amp stage requires
absolutely no bias adjustment, ever. And because it's self-biased, matched
tubes are not required. Simplicity has it's benefits.
The power amp stage is configured as parallel, triode, single-ended.
This allows the generation of the maximum amount of even harmonics
possible in the power amp and insures that they will not be cancelled out
(as would be the case in a push-pull arrangement). In addition, the
output transformer is rated well above the output power, allowing it
to move all of the tone you put into it, out to the speaker load,
with virtually no transformer distortion. Finally, the power supply circuit is
"over-designed" to reduce hum, and deliver huge bass response.
* Put it in the studio, where this amp delivers a liquid tone at studio volumes.
* Put it on stage, and crank the gain for an experience you won't forget.
Output: 20 Watts continuous / 25 Watts peak @ 4 ohms
That's a conservative output power rating. When this amp is
cranked up, it's as loud as some amps rated much higher.
Tube compliment:   2 x 6L6GC,   2 x 12AX7
Note: EL34's can be used in place of the 6L6GC's. Just plug them in and play!

Tim Moore is heard here playing a Strat, doing what he does so very well.
Thanks to Rob Rierson (another great guitarist) for his critical ear and expert recording.
These recordings were produced without effects. The setup is: Strat w/ EMG pickups, Blue Moon, SM57,
preamp, and Tascam 24-bit capture to hard drive.
Jimmy Murray, a true Les Paul guru, played multiple guitar tracks and produced these clips
using one of his Les Paul "museum pieces".
These recordings were augmented with reverb and backing intsruments.
