Independent shopping perspective
The Korena take
Built around the two-channel Bogner Uberschall format, this Synergy tube preamp module focuses on high-gain guitar sounds. The blue Twin Jet channel uses Gain, Volume, three-band EQ, Pre-EQ and Cut controls; the red Super High Gain channel substitutes Boost for Cut. The module is described as a choice for extended-range and drop-tuned guitars, with separate channel controls for shaping each side of the module within a Synergy rig.
Strong match
Who this is for
- Extended-range or drop-tuned guitar rigs seeking the module’s described high-gain sound.
- 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.
