Independent shopping perspective

The Korena take

Designed as Steve Vai’s two-channel Synergy module, the VAI puts a clean-to-slight-breakup blue channel alongside a red channel built for heavier gain and harmonic sustain. Each channel has Gain, Volume and three-band EQ, then its own pair of voicing switches: Fat and Bright on blue, Bright and Boost on red. It gives a Synergy rig two distinct starting points that can be adjusted from the module’s front panel.

Strong match

Who this is for

  • Building a Synergy guitar rig with separate clean, breakup, high-gain and sustaining sounds.
  • Direct recording, lower-stage-volume setups, and compact guitar rigs using the Synergy module system.

Consider the trade-offs

When to look elsewhere

  • Switching between both channels in older single-channel Egnater or Randall modular units.

Final check

Know before you order

  1. 01In older single-channel Egnater and Randall modular amps/preamps, select either module channel with the secondary switch; their hardware cannot switch between both.
  2. 02Set the secondary switch to Dual in units with the switching circuit for both module channels.
