Manufacturer's ID: VAI MODULE

What we say:

At A Glance:

The Steve Vai Signature 2 Channel Preamp Module has been designed through a collaboration between the guitar legend and Synergy Amps to bring Steve's vision for the perfect amp into fruition. The result is an all-tube module which is compatible with Synergy hardware, and features two channels and an intuitive layout to  make dialling in your desired tone quick and easy.

Features We Love:

Two Channels

The Vai Signature features two distinct channels, the "blue" channel caters for clean tones and features dedicated gain, volume and 3-Band EQ controls and Fat and Bright switches for quick tweaking of your tone. The "red" channel is responsible for the overdriven tones, featuring dedicated gain, volume and 3-Band EQ controls and Bright and Boost switches. Vai has a distinctive signature tone and we were surprised that it was achievable with such a simple set of controls, proving yet again that less can be more!

Synergy Amps

Synergy began designing amps as a way to bridge the gap between boutique amps and modern manufacturing. The result is a series of heads which are compatible with a selection of high-quality modules designed and made by well known and obscure high-end amp manufacturers. This not only makes boutique amp sounds available to the regular musician, it also brings an added level of reliability to those sometimes fragile handmade amps. Because the modules can easily be swapped out and combined, the approach is ideal for stage and studio use, flexibility and reliability are key and it's an affordable way to completely change your arsenal of tones without ever compromising on quality.


The Vai module is obviously compatible with Synergy heads, however, as it features Dual/Single switch, it is compatible with older single channel Egnater and Randall modular amps/preamps that do not accept the dual channel modules.
