Synergy SYN-20IR Modular Head

The Synergy SYN-20IR Modular Head is a true studio powerhouse, combining the warmth and response of real tubes with next-level flexibility for modern recording. With its modular preamp system, built-in impulse response technology, and versatile power amp controls, the SYN-20IR delivers legendary amp tones directly to your DAW.

The Synergy SYN-20IR Modular Head is a host for Synergy Amplifier Modules. At Front End Audio, we love how the Synergy SYN-20IR streamlines the recording process while keeping everything 100% analog at the core. You get the unmistakable feel of an EL84-driven power section, the option to load modules modeled after iconic amplifiers, and pro-grade direct recording via XLR and headphone outputs. For producers and guitarists who demand both authenticity and convenience, the SYN-20IR is a dream come true.

Legendary Tube Tone Meets Studio Convenience
The SYN-20IR is built around Synergy’s patented modular preamp system, which lets you easily swap in modules designed with the original amp builders themselves—Friedman, Diezel, Bogner, Soldano, and more. Each module features genuine 12AX7 tube circuitry for uncompromised tone. Paired with the SYN-20IR’s onboard clean channel and EL84 power section, you get three independent tube-driven channels that cover everything from pristine cleans to crushing gain.

Advanced IR and Power Amp Control
Unlike traditional tube heads, the SYN-20IR is fully optimized for direct recording. Its high-resolution IR engine delivers professionally captured cabinet sounds with less than 1ms of latency—ensuring an immediate and realistic feel. You can assign one of four IRs to each channel, or load your own custom IRs via the free Synergy Editor software. Add to that the unique "Structure" and "Reactance" controls, which let you reshape the response of the power amp section, and you have an unmatched level of tonal flexibility right from the head.

Seamless Cab-Less Recording
With the SYN-20IR, there’s no need for an external cabinet or load box. Simply connect directly via the balanced XLR output or the dedicated headphone jack and enjoy authentic tube tone at any volume, even in total silence. The ultra-transparent effects loop and MIDI programmability make it easy to integrate into any recording setup, while the USB connectivity and Synergy Editor software allow you to manage IRs, assign presets, and save up to 128 user configurations.
