Independent shopping perspective
The Korena take
Built around two Powerball channels, this all-tube Synergy module puts separate gain, volume and three-band EQ control on each channel. Gain Lo/Hi and Mid Boost switches extend the available control per side, while two 12AX7 tubes handle the preamp section. It suits players assembling a compact guitar rig, recording direct, or working at lower stage volume within the Synergy system. The onboard Cathode Select setting is factory-set to the Powerball designer’s preferred position.
Strong match
Who this is for
- Building a compact guitar rig around two independently controlled Powerball preamp channels.
- Direct-recording and lower-stage-volume setups using the Synergy preamp module system.
Consider the trade-offs
When to look elsewhere
- Older single-channel Egnater or Randall units cannot switch between the module’s two channels.
