Independent shopping perspective
The Korena take
PRS’s Sonzera 20 is a 20W, two-channel tube combo built around a 12-inch Celestion V-Type speaker. The clean and gain channels give you separate routes from clear, responsive parts into controlled breakup and heavier drive, while spring reverb and a series FX loop keep time-based effects easy to manage. Its included footswitch handles channel changes and reverb on/off, so the amp’s main changes remain accessible during a set.
Strong match
Who this is for
- Rehearsal or stage sets that need footswitchable clean, gain, and reverb changes.
- Studio sessions using a series effects loop for delay, modulation, or reverb pedals.
- Players who want separate channel controls rather than one shared gain path.
