1. All-Tube Design: The VAI Signature Pre-Amp is an all-tube preamp module, meticulously crafted to deliver exceptional tone and performance.
2. Dual Channels:
   • Channel Blue (Clean):
     • Controls: Gain, Volume, 3-Band EQ (Bass, Middle, Treble)
     • Switches: Fat & Bright
     • This channel covers everything from sparkling cleans to slightly broken-up American tones.

3. Tube Configuration:
   • The VAI module features two 12AX7 preamp tubes, ensuring rich harmonic performance.
4. Cathode Select Switch:
   • A three-position switch allows you to configure the input tube bias setting for optimum input gain and bass response.
   • Choose from three popular combinations:
     • Setting 1: USA voiced modules (1.5K resistor and 22uF capacitor).
     • Setting 2: British style modules (2.7K resistor and 0.68uF capacitor).
     • Setting 3: Steve Vai’s preferred setting (1.8K resistor and 1uF capacitor).
5. Dual/Single Switch:
   • Use this switch to adapt the module for older Egnater and Randall hardware.
   • Set to Dual when using the module in units that have the switching circuit to access both channels.
   • Set to Single for single-channel-only amps/preamps (top channel of the module activates when selected).
