OPERATING INSTRUCTION OVERVIEW: CONGRATULATIONS on your purchase of the V-TWIN as your choice of rack mount pre-amplifiers! This one space wonder is the perfect adddition to any system. From a simple two or three space rack, to the world class coliseum size rig utilizing multiple pre-amps, the V-TWIN will likely become a favorite right away. In the studio it will become invaluable to you for capturing great direct to tape sounds fast and effortlessly.
OVERVIEW: (Continued) At this time, we would like to remind you that for any rack guitar system to sound amazing, it must not only have a great pre-amplifier such as the one you have just purchased...it must be combined with a musically warm and expressive power amplifier that is tuned to the needs of the guitar as well ! May we humbly suggest trying one of the three all-tube power amplifiers that we have worked for years developing specifically for this application.

As we mentioned earlier, each channel of theV-TWIN contains three different Modes voiced for different styles of playing.
CONTROLS: VOLUME: (GAIN) INPUT This is by far the most powerful control in the pre-amp. It not only determines the V-TWIN'S overall Gain amount, shape and sensitivity...but it is also a powerful Tone control. Generally speaking, whatever is dialed here ultimately determines the V-TWINS' personality. Set low, GAIN it allows cleaner, brighter sounds with enhanced dynamic response, especially in the higher frequencies. Set high, the whole personality of the channel becomes darker, fatter and more overdriven.
BASS: This control blends in the lower frequencies, and its effectiveness, again, depends on the setting of the TREBLE Control. It should be set with moderation, as extreme settings in either low or high directions can produce an unbalanced tone.
This control is the pan pot for the MIX MODE. It is responsible for the blend of the SOLO and CLEAN Channels when MIX: the MIX function is called up, either via the Footswitch or when both channels MANUAL / FOOTSWITCH Front Panel mini toggles are set to the MANUAL position. ( Clean Channel = CLEAN, Solo Channel = SOLO.) INPUT GAIN TREBLE MIDDLE BASS MIX PRESENCE MASTER SOLO SOLO CHANNEL 1 3 This control allows any blend of the two channels to be used when in MIX.

They faithfully reproduce both SOLO both SOLO and CLEAN Channel sounds similar to those you are accustomed to hearing from your power amp and speakers. The output level is L L L determined by the Front Panel MASTER Control setting. At extreme settings it may be possible to R R R overload the console's input circuit. Medium MASTER Control settings are probably sufficient for most situations.
