Page 4: Getting Acquainted
GETTING ACQUAINTED The Valvulator™ GP3 is truly a leap forward in guitar amplifier technology. It breathes and dynamically responds to your playing technique exactly the way a great guitar amp should. Over twenty years of intense research, experimentation and design development have gone into every aspect of the creation of this unique sound-sculpting tool, from the stacked grained aluminum front panels with custom machined knobs to the proprietary output circuitry which precisely emulates the behavior of a cranked low power amplifier. - Page 5 But in reality, these are just stepping stones in a greater journey. We believe that the VHT player is attempting to develop something inside themselves, which is unique and seeks definition. Once you become intimately familiar with the capabilities of the GP3 you will of course eventually be able to call up a desired classic amplif ier signature at will.

Page 6: Warm-Up Sequence
WARM-UP SEQUENCE As with all tube amplifiers, gradual warm-up greatly extends tube life and tone quality. There are two major wear factors which can noticeably impact the performance of preamp tubes. The first is Filament Stress. The second is called Cathode Stripping. Filament Stress occurs when a cold tube is allowed to heat up too quickly. -
Page 7: Input Stage
GP3 utilizes a 12AX7 preamp tube in a unique configuration that uses very little power and produces pleasing power amplifier distortion and harmonic components. Thus the Valvulator GP3 leads the way toward a new class of amplification, the Very Low Power Amplifier. -
Page 8: Tone Controls
TONE CONTROLS VHT amplifiers are well known for their “tone controls that really work” and this legacy is carried on here. The passive tone control circuitry in the GP3 is interactive in nature and separate tone circuits and controls are provided for each channel. -
Page 9: Graphic Equalizer
truly independent circuitry provides much more tonal range and flexibility as well as cleaner signal paths, no signal bleed between channels and lower noise. GRAPHIC EQUALIZER This is probably one of the most unusual GRAPHIC EQ designs ever created. Not just some randomly selected frequency bands;... -

This means the player can get more sparkle and zing out the guitar strings without making the bass notes sound muddy. Like all VHT tone shaping functions this is a subtle and effective feature to help you fine-tune your sound. - Page 11 depending on the gain setting and assigns operation of this mode to any selected channel. (Selects user defined MIDI preset Bank 1). BOOST (User Bank 2) – Fixed gain boost on the CLEAN channel, variable gain boost on the RHYTHM and LEAD channels. Assigns operation of this mode to selected channel. (Selects user defined MIDI preset Bank 2).

Page 12: Midi Controller Numbers
To write a patch to one of the USER PROGRAM BANKS, first confirm that the rear panel SELECT/OMNI switch is set to OMNI Connect the MIDI OUT from your MIDI controller to the MIDI IN on the back of the GP3. Next, power up the GP3 and the controller. Now you are ready to write a patch. - Page 13 APPENDIX I MIDI FACTORY PROGRAM MAP PROGRAM FUNCTION/COMBINATION MUTE CLEAN CLEAN BRITE CLEAN CLEAN BOOST CLEAN LOOP CLEAN CLEAN REMOTE CLEAN BRITE CLEAN BRITE BOOST CLEAN BRITE LOOP CLEAN BRITE CLEAN BOOST CLEAN LOOP CLEAN CLEAN BOOST LOOP CLEAN BOOST CLEAN BOOST REMOTE...
