Synergy SYN-20IR Combo
Synergy · amplifier
The Synergy SYN-20IR Combo puts the three-channel 20-watt modular platform with onboard impulse-response simulation into a 1x12 combo, so the amplifier, speaker and direct-output section arrive as one unit. As with the rest of the system it accepts interchangeable all-tube preamp modules voiced after specific amplifiers, meaning the combo's character is defined by whichever module is fitted rather than by a fixed circuit. It suits players who want modular amp voicing in a single self-contained box for both stage and direct recording.
