The VTX212B features full 3-channel operation with independent Gain, Level and Tone shaping circuits. The DSP section has 15 Multi effects including Chorus, Flange, Phase Shift, Vibrato, Octave Down, Touch-Wah and Reverse Wah. Each of these can be set for depth, plus the Tap button on the front controls speed. The VTX212B also has 15 Delays with adjustments for Single delay with 4 levels, Echo delay with 4 levels, Tape delay with 4 levels and Echo / Effects combo with 3 levels. Each of these effects can be set with the Tap button for speed as well. A separate Reverb control adds even more to the array of effects. Front panel RCA CD Input jacks allow you to play along with your favorite CD or tape. The rear panel Insert Jack allows you to connect your own effects for greater flexibility. Channel switching and DSP may be controlled by means of a footswitch, which also allows access to two DSP presets on each of the three channels. The top-mounted electronic tuner lets you get tuned and stay in tune any time the amplifier is on. You may change the DSP settings by rotating the DSP controls - these changes will remain active until a different channel is selected, but will not be there for later use unless they are saved. To save a new DSP preset to a channel, first make the desired DSP changes. Then press and hold the Save/Tap button for about three seconds. The Save/Tap LED will flash through three quick sequences, indicating the preset was saved. The new preset is stored for that channel and will remain in memory until a new preset is stored for that channel or the factory presets are restored. The Crate three-button footswitch supplied with the VTX65 allows access to an additional DSP preset for each channel of the amplifier. When the footswitch is connected to the amplifier as shown below, the "original" DSP presets are active for each channel when the #3 footswitch LED is illuminated. These are referred to as "DSP Bank 'A'." When the #3 button is switched and the LED is out, a second DSP preset may be stored and recalled for each channel - "DSP Bank 'B'." The VTX212B combines great sounding analog with total control over the DSP section and with vintage styling. These amps were designed for the player who is into the vibe and styling of the V-Series, but wants a 3 channel analog amp with "tweakable" digital effects and the ability to program up to six effects in the three channels.
