MESA/BOOGIE
STUDIO .22 PLUS
OWNER OPERATING INSTRUCTIONS
CONGRATULATIONS! You've just become the proud owner of the liveliest sounding, easiest
operating, small caliber amplifier there is... and you're sure to enjoy it! When friends and strangers
come up to compliment you on your tone, you can smile knowingly ... and hopefully you'll tell them a
little about us! Because word-of-mouth is still the best way to spread the news about MESA/Boogie.
GREAT SOUND Many months of patient, painstaking R & D were spent developing the Studio .22
Plus so it would deliver professional quality sound that lives up to the MESA/Boogie reputation. (So
even though our other models have more power and perhaps more features, your Studio .22 was
designed and built as a totally professional, no-compromise instrument.) We figure that once you're
hooked on great amp performance, you'll find yourself playing better and enjoying it more.
GREAT SIMPLICITY One of the Studio Boogie's greatest virtues is its incredible simplicity of
operation. It's nearly impossible to come up with a bad sound or a wrong setting. And here, to help
you get started, is a brief explanation of your new amp's features and controls.

FRONT PANEL FEATURES

INPUT JACK This ¼ inch jack is the instrument input to your Studio amplifier. Patented "Dual Mode"
circuitry makes this single jack work for both Rhythm and Lead... providing very high headroom for
sparkling clean rhythm and super high gain for monstrous lead playing. Be sure to use a good
quality, shielded guitar cord.
FOOTSWITCH JACK This ¼ inch jack connects to the Lead/Rhythm footswitch via the un-shielded
cable provided. When the red LED on the footswitch box is illuminated, the Studio .22 is in the
RHYTHM mode...red equals rhythm. Stepping on the button switches the amp into the LEAD mode
and the light goes out.
Should you lose or forget your footswitch, you can activate the Lead mode by plugging a cable into
the footswitch socket and shorting the tip of the other plug against the chassis or one of the metal
handle caps.
VOLUME This control, which could also be called "preamp gain", establishes the amplifier's overall
sensitivity to your guitar's output. It is active in both Rhythm and Lead modes, and must be mixed in
conjunction with the Master (or, when in the Lead mode, both Masters). In the Rhythm mode, the
maximum clean setting is usually around 6 (varies with stronger or weaker pickups) and most players
find their favorite cleanest brightest spot between 3 and 5. But if you want some break-up in the
Rhythm model turn the Volume up high.
In the Lead mode the Volume knob is intentionally less sensitive so that there is no need to 'Ire-set" it
for the two modes. With most guitars, distortion begins around 2 with a real nice sounding blues-type
tone reminiscent of old Fenders turned up loud. Settings above 3 or 4 produce the more modern,
"monstrous" distortion sounds. Gain and distortion increase slowly as the Volume setting is
increased, often producing the tightest, best sounding heavy crunch tone between 7 and 9.
