Independent shopping perspective
The Korena take
Synergy’s SYN-20IR is a 20W EL84 tube amp head built around a three-channel layout: a clean channel plus two channels for compatible Synergy preamp modules. Its selectable A, B, and C Power Amp Structure modes and Reactance control give you several ways to shape the power-section response. Four programmable IR slots, USB-based IR management, XLR and line outputs, and a headphone output support direct recording, monitoring, and stage routing. The included three-button MIDI footswitch handles channel, IR, and amp-structure switching.
Strong match
Who this is for
- Building a modular guitar rig with official Synergy preamp modules sold separately.
- Sending cabinet-simulated output to a mixer, recording interface, or headphones.
- Switching channels, IR settings, and amp structures from the included MIDI footswitch.
Consider the trade-offs
When to look elsewhere
- Players who need preamp modules included with the amp; compatible Synergy modules are sold separately.
