MESA/BOOGIE
.50 CALIBER SERIES
OWNER OPERATING INSTRUCTIONS
CONGRADULATIONS! You've just become the proud owner of the boldest sounding, easiest operating
50-watt 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 .50 Caliber so it
would deliver professional quality sound that lives up to the MIESA/Boogie reputation. (So even though
the big Mark III Boogies have more power and more features, your .50 was designed and built as a
totally professional, no compromise instrument.) We figure that once you're hooked on a great amp
performance, you'll find yourself playing better and enjoying it more.
GREAT SIMPLICITY One of the .50 Caliber'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 1/4 inch guitar 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 1/4 inch jack connects to the Lead/Rhythm footswitch via the un-shielded
cabled provided. When the red LED on the footswitch box is illuminated, the .50 Caliber 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 is active in both Rhythm and Lead Modes. It establishes the amplifier's overall
sensitivity to your guitar's output and must be mixed in conjunction with the Master.
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 mode, turn the volume up high.
