Description
The Synergy Preamp Module - Diezel VH4 brings Peter Diezel's most recognized high-gain amplifier voice into Synergy's interchangeable all-tube preamp system. Personally designed by Diezel, this dual-channel module is built around the aggressive but highly articulate character associated with the VH4. It's a strong choice for rock and metal players who want plenty of gain without giving up note definition, especially when tight rhythm work and saturated lead tones need to come from the same module.
Both channels have their own Gain, Volume, Bass, Middle, and Treble controls, so you can build two genuinely independent sounds rather than sharing an EQ between rhythm and lead settings. Two 12AX7 preamp tubes provide the all-tube gain structure. An internal three-position Cathode Select switch also changes the input tube's bass response, which affects the overall tightness and feel. The module comes from the factory in Peter Diezel's preferred Position 2 setting, using a 2.7K resistor and 0.68uF capacitor.
For a modular rig, the independent channel controls are a big part of what makes the VH4 practical. You can set one side for tighter, more controlled rhythm gain and use the other for a fuller lead sound, then swap the entire preamp module when your needs change. We think this is one of the more straightforward Synergy choices for players specifically looking for Diezel's combination of high gain, fast response, and articulation without committing to a full VH4 amplifier.
