QUAD PRE-AMP
OWNER OPERATING INSTRUCTIONS
CONGRATULATIONS! By becoming the owner of the Mesa Quad Pre-amp, you have taken the
first step into a new world of tonal freedom. You are among the first of a new breed of players who
require the latest in digital footswitchability and yet refuse to sacrifice the old world "soul" of an all
tube amplifier. The Quad does this and much more.
You will be pleased to know that four years of planning and research went into perfecting this
instrument. Our experience as the leading force in guitar amplification for fourteen years helped us
in designing the Quad. This combined with input from players worldwide made it possible to deliver
sophisticated features in an easy to use format. So relax, and don't be intimidated! We've included
a complete description of all the controls and how they operate, as well as a very helpful settings
sheet. These are guidelines. Start here and as you become a more confident "tone pilot", feel free
to solo.
The Quad is a sensitive instrument, much like the guitar. Use this to your advantage. Read the
Owners Manual. Understanding the controls will help you create sounds you won't believe. With
time and patience you will find sounds that are uniquely yours and will provide you with a lifetime
of satisfaction and enjoyment from your music.
NOTE: THE QUAD PRE-AMP WAS DESIGNED FOR USE WITH THE SIMUL CLASS 295 OR
STRATEGY 400 STEREO POWER AMPS. THESE ARE ALL TUBE POWER AMPS AND ARE AN
INTEGRAL PART OF THE MESA RACK SYSTEM FOR GUITAR. USE OF THE QUAD PRE-AMP
WITH ALTERNATIVE POWER AMPS IS NOT RECOMMENDED.
TWO INDEPENDENT CHANNELS, FOUR MODES!
To achieve greater tonal flexibility and footswitchable freedom, the Quad is separated into two
channels sharing one common input. Each channel offers two modes and a pre-assignable 5 band
graphic equalizer. Channel 1 is very similar to the Mark IIC, while Channel 2 is very much like the
Mark III. These were the premier guitar amps for the last five years, winning the praise of such
guitar giants as Steve Lukather, Lee Ritenour, Michael Landau, Stevie Ray Vaughn, and many
more. We found that many of these players used more than one amp and switched between them
for different sounds. A great idea but very heavy and bulky to move requiring custom made
switching systems. Thus, the need for the Quad. Two incredibly versatile amps in one taking up a
mere three spaces in your rack.
THE QUAD HAS REVERB! And you've got to hear it to appreciate it. By combining two different
sizes of 3 spring reverb tanks, we've developed a reverb that dares the digitals. With three
dimensional depth and a perfectly smooth decay we feel confident in saying this is the most
beautiful sounding reverb ever found in a guitar amp. Combine these features with a stereo effects
loop and stereo outputs and you can imagine the possibilities. The fun has barely begun.

Summary of Contents for Mesa/Boogie QUAD PRE-AMP

  • Page 1 The Spirit of Art in Technology CONGRATULATIONS! By becoming the owner of the Mesa Quad Pre-amp, you have taken the first step into a new world of tonal freedom. You are among the first of a new breed of players who require the latest in digital footswitchability and yet refuse to sacrifice the old world "soul"...
  • Page 2 CHANNEL 1: RHYTHM 1, LEAD 1: This channel would be considered the more "normal" of the two, delivering all the classic "boog" tones you've come to love. RHYTHM 1: A mode primarily designed to produce the ultimate in clean, sparkling, warm rhythm sounds.
  • Page 3 You will notice a difference in the taper of the two volume controls. This is an intended difference and proves to be an integral part of the Quads versatility. Channel 1's Volume is much like that of the Mark III. Very smooth, responsive and dynamic. The sweet spot is usually found somewhere between 6 and 7½.
  • Page 4: Treble Control

    lead mode. By raising the frequency of the shift, the higher frequencies have a "soaring" feeling unequaled in any other guitar amp. Higher strings, when bending, seem to reach for the stars with purity and focus. The Treble Shift in Channel 2 is manually operated and has no automatic bypass function.
  • Page 5 PULL DEEP: This pull function is very self-explanatory. When pulled, the bass frequencies are accentuated, creating a deeper, more robust bottom end. Although essentially a bass boost, much like the Bass Shift, Pull Deep works on a different set of frequencies. This tends to "deepen" the low end and give it that "extended"...
  • Page 6 5 bands, makes for another powerful tone control section. Although the equalizers are an integral part of the Quad pre-amp and provide many possibilities, they can be bypassed at any time. All you tube purists will be glad to know months of R & D went into perfecting the Quad's tone before the equalizers were added and scrutinized.
  • Page 7 REVERB: This control determines the mix between the "dry" (non-effected) and "wet" (reverb) signal. At zero, only the dry signal is heard. As the control is turned up the wet signal is mixed with the dry signal. The result is reverb. The Quad has unique reverb as compared with other guitar amps or pre-amps.
  • Page 8: Rear Panel Features

    INPUT: This 1/4 inch-jack is the main input for the Quad. It is an insulated Mono input designed for use with one instrument. Always use a shielded guitar cable of good quality when connecting the instrument to the Quad pre-amp. - 8 -...
  • Page 9 EFFECTS LOOP: The effects loop in the Quad is a Stereo loop with a “mono” (or single) send and “Stereo” (or two) returns. It is equipped with a "Low Level/Line Level" switch that makes for easy interfacing with virtually all effects. When using floor pedals or "inexpensive" rack effects, "Low Level"...
