[. . . ] QUICK REFERENCE SETTINGS CARVIN ENGINEERING DATA V3M/V3MC MICRO 3-CHANNEL TUBE GUITAR AMP OPERATING MANUAL V3M head V3MC 1x12 combo Congratulations on your purchase of the V3M all tube amplifier. They have been used by top professionals like Frank Zappa, Steve Vai, Craig Chaquico, Allan Holdsworth, and other great musicians. You will discover that these amplifiers represent a significant sound improvement over conventional amplifiers. Spend time with your new V3M and get to know its many sounds. TECHNICAL DESIGN OF THE V3M The V3M design criteria was to build a high peformance 3-channel tube guitar amplifier in a compact, yet powerful package.

AC POWER & FUSE Make sure the cord is securely inserted into the back of the unit. No attempt should ever be made to defeat or use the amp without the ground connected. If the fuse blows, unplug the amp and check the AC power connection, your speaker connection and all tubes. If replacing the fuse does not restore the amp to working order, check the power amp tubes. If no problem is found and the fuse blows again, your amp may need service. FRONT PANEL 1. POWER SWITCH The POWER switch is to be utilized as the master ON/OFF switch. As the amp is turned ON, one of the 3 channel LEDs will illuminate as your ON indicator. GUITAR INPUT A standard 1/4" input jack feeds all channels through the SELECT switches. Typical cable capacitance should be under 50pf--the longer the cord, the greater the capacitance (you can measure this with a capacitance meter). A long cable with high capacitance will reduce the overall treble response from your pickups. 15. PRESENCE For added clarity, the CH 3 PRESENCE controls only the highest guitar harmonics in the 5-10k Hz range. · The CH1-2 footswitch LED OFF will show CH1 active when CH3 is turned off. To change the volume of all channels without upsetting the balance between the 3 channels, use the MASTER volume control. 22. It's frequency range is from the mid to high range of the tonal spectrum. Careful adjustment with the TREBLE control will make this feature very useful. 33. AC VOLTAGE SWITCH (120V/240V) It is very important to verify the proper setting before plugging the amp in. This switch sets the amp to use either 120VAC or 240VAC ranges from the wall socket. The V3M will not require re-biasing if used at 50 or 60Hz, or if the AC voltage switch is changed for travelling to different areas of the world. MASTER SECTION 3. MASTER VOLUME The MASTER controls the output of all 3 channels and effects. Once your individual channel levels are set up and balanced, use the MASTER to change your overall volume. 10. DRIVE MODE 3-POSITION SWITCH (CH3) The switch labeled BRIGHT/SOAK is a 3-position switch that changes the gain structure of the channel. [. . . ] DRIVE CONTROL For mild tube saturation, set the DRIVE control below "4". For more harmonics and dynamic playing, set the control between 4 & 6. For full blown overdrive, set the control between 6 and 10 (your guitar volume should be turned all the way up). Because the V3M has been "Hot Rodded" with so much gain in the DRIVE control, you may encounter feedback. [. . . ]
