Hello from the Tone Farm... ..You, 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 pre-amplifier and by choosing this wonderful unit, you have become part of the MESA family...WELCOME! Our goal is to never let you down. Your reward is that you are now the owner of an archetypal guitar pre-amp, bred of fine all tube amp heritage...
PRECAUTIONS 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: Do not expose amplifier to moisture, rain or water, direct sunlight or extremely high temperatures. Always insure that amplifier is properly grounded. Always unplug AC power cord before changing tubes. Avoid direct contact with heated tubes. Insure adequate air circulation around this pre-amp. Keep amplifier away from children.
PRECAUTIONS V TWIN Congratulations on your purchase of the V-TWIN! This handbuilt, all tube, 3 mode preamp combines all the features and versatility found in our trademark pre-amplifiers and offers them up in a compact and rugged floor format. Historically, floor pre-amplifiers have been used primarily to add or enhance gain and flexibility to existing stand alone combos or heads.
BASIC SET-UP: Set the controls as per this diagram. Then run through the 3 sounds by using the Channel Select footswitch and the Alternate Channel push key located between the Middle and Treble controls.
TO POWER AMP: TO POWER AMP This jack provides a hotter signal level and a slightly different E.Q. curve for interfacing with the FX Return stage of any amplifier, or S C 2:N simply to use V-TWIN as a stand alone pre-amp with an MESA existing power amplifier. (We suggest an all tube power amp...e.g. MESA'S Stereo Simul-Class 2 : Ninety or Fifty / Fifty.
SAMPLE SETTINGS: Now that you have a better understanding of the Outputs and set-up procedures, let's listen to a few sample settings...Keep in mind that if you are using the TO GUITAR AMP jack, the setting of the host amp determines much of the overall character of the sound. We suggest you start by plugging into the host amplifier first and dialing up a balanced and warm clean rhythm sound.
SAMPLE SETTINGS: 4 GAIN (continued) BASS MIDDLE TREBLE STINGING BLUES: 5 GAIN Neck or Bridge Single BASS MIDDLE TREBLE CRUNCH RHYTHM: 6 GAIN PRESENCE MASTER PRESENCE MASTER Bridge Humbucking BASS MIDDLE TREBLE JUICY HIGH GAIN LEAD: BLUES MODE: SOLO MODE: PRESENCE MASTER Bridge Humbucking SOLO MODE: HINTS These settings are mere suggestions that should get you in the ball park so to speak...taking into account pick-up differences and host amp / power amplifier variables.
