SynergySYN-20IR 20W 1x12 Guitar Combo Amp - Silver Steer
1/8
Independent shopping perspective
The Korena take
Built around a 20W EL84 power section and a 12-inch Celestion Vintage 30, the SYN-20IR is a three-channel guitar combo with an onboard clean channel and two channels for a Synergy preamp module. Its modular format lets you change the preamp section without changing the whole amplifier. For recording, headphone practice, or a direct front-of-house feed, the integrated IR system offers four per-channel programmable slots with under-1ms latency. A global master volume, series effects loop, MIDI presets, and XLR output make it suited to a managed multi-sound rig.
Strong match
Who this is for
- Players who want clean and module-based channels in one 20W 1x12 tube combo.
- Recording, headphone practice, or direct front-of-house setups using the onboard IR system.
- Preset-based rigs needing up to 128 programmable MIDI presets and per-channel IR assignments.
Consider the trade-offs
When to look elsewhere
- Players who do not want to purchase official Synergy preamp modules separately.
- Rigs that need more than the combo's three available channels.
