Hello from the Tone Farm... YOU, the smart player and all around intuitive human, have put your trust in us to be your amplifier company. This is something we do not take lightly. Our reward is that we've made a classic amplifier and by choosing this amplifier, you have become part of the MESA family.

PRECA UTIONS & W ARNINGS Your MESA/Boogie Amplifier is a professional instrument. Please treat it with respect and operate it properly. USE COMMON SENSE AND ALWAYS OBSERVE THESE PRECAUTIONS: YOUR AMPLIFIER IS LOUD! EXPOSURE TO HIGH SOUND VOLUMES MAY CAUSE PERMANENT HEARING DAMAGE ! No user serviceable parts inside.
OVERVIEW: Congratulations on choosing the F Series as your amplifier and welcome to the M esa/Boogie family! The new F S eries amplifiers combines high gain lead performance, an amazing mid-gain crunch or blues sound and a bold and beautiful clean sound in a simple 2 Channel, Three Mode, all-tube, hand-built package that begs to rock.
OVERVIEW: (Continued) darker than that of its lower power family members but posses a depth and punch found only in amps of this serious-gigging horsepower range. Our legendary 60/100 switch has been included and allows you to detune the power section to achieve the brighter , more clippable feel of the F-Series .

GAIN: This is by far the most powerful control in each of the three different Modes that are activated by the Mode switch. It not onl y determines the overall gain amount, shape and sensitivity of the Mode selected...but it is also a powerful T one control.
MID: (Continued) pressed, even feel to the strings and therefore less apparent resistance to the pick. As the MID control is increased, ( 1 1:00 through 1 1:30 ), the sound is rounded-out and filled-in with a focused mid attack appearing rather quickly .
MASTER: (Continued) -rectly to a mixing board or recorder , this control will determine the amount of signal you will be sendi ng via this jack. In this application it is usually best to start with the MASTER controls set to ( 7:00 ) and gradually increase them to the proper level.

FX MIX: This control determines the dry/wet blend of the FX Loop signal in relation to the unaffected signal. Set to 10% you will experience only the dry signal (no noticeable FX) and at a setting of 90% the entire signal will be wet (total effect.) For the best results.

TUBE NOISE & MICROPHONICS: Y ou may occasionally experience some form of tube noise or microphonics. Certainly no cause for alarm, this quirky behavior comes with the territory and the T one.
DIAGNOSING PREAMP TUBE PROBLEMS: Because your amplifier is an all tube design, it is quite possible that you will at some point experience minor pre-amp tube noise. Rest assured - this is no cause for alarm and you can take care of the problem yourself in a matter of minutes by simply swapping tubes.
into oscillation or start crackling or any other form of bizzare noise, it is considered normal and functional. BIAS ADJUSTMENT : (a continuing series) NOTE: An article written by Randall Smith that we thought you might find interesting.
it doesn’t need to be adjustable.” BIAS ADJUSTMENT : (Continued) When you set the bias (whether it’s by selecting the right resistors, as we do, or adjusting a trimmer — which is quicker) what you are doing is establishing the correct amount of idle CURRENT that flows through the power tubes.
BIAS ADJUSTMENT : (Continued) tubes. The thinking is that adjusting the bias to each tube separately eradicates the inheren t differences between the tubes by insuring that the same current flows through each oneAgain, this has some merit .
SPEAKER IMPEDANCE MA TCHING & HOOK-UP GUIDE: IMPEDANCE: Wiring up speakers to provide the most effective load and making sure that all of them are in phase will help in creating the best sound possible.
SPEAKER IMPEDANCE MA TCHING & HOOK-UP GUIDE: (Continued) P ARALLEL: When wiring in parallel, the resistance of the speakers decreases. T wo 8 ohm speakers wired in ( hooked-up ) Parallel results in a 4 ohm load. It’s easy to calculate the effect of a resistive load when all the speakers are all the same resistance.
