SynergySYN-20IR Tube Amp Head and Friedman DS Module Bundle
1/14
Independent shopping perspective
The Korena take
The SYN-20IR and Friedman DS bundle combines a 20W EL84 tube head with a two-channel DS preamp module. Alongside the head’s dedicated clean channel, the DS module offers three-band EQ and a gain boost for shaping its clean-to-overdrive range. Four programmable IR slots, MIDI preset storage, selectable power-amp modes, and XLR, line, headphone, and speaker connections make this a flexible modular amp setup for players building a controllable rock-oriented rig.
Strong match
Who this is for
- Guitarists who want a dedicated clean channel plus Friedman DS controls for clean, crunch, and lead settings.
- Studio or recording rigs using XLR, line, or headphone outputs with onboard cabinet simulation.
- MIDI systems that need up to 128 programmable presets and channel-specific IR assignments.
Consider the trade-offs
When to look elsewhere
- Players who need more than four onboard IR locations.
- Players looking to use preamp modules outside the official Synergy module range.
