Synergy SYN-20IR 20W 1x12" Guitar Combo Amp - Brown Ostrich

Picture an entire wall of iconic tube amplifiers condensed into a single, stage-ready 1×12” combo. Enter the Synergy SYN-20IR, which redefines what an all-tube amplifier can be through its patented modular architecture and lets players physically swap preamp modules licensed from the legendary likes of Soldano, Bogner and Friedman to transform the amp’s voice in seconds. Powered by a 20W EL84 tube power section, the SYN-20IR pairs an onboard American-style clean channel with ultra-low-latency IR technology for direct recording or FOH use without sacrificing real tube feel. With a Celestion Vintage 30, programmable Structure control and studio-grade connectivity, this three-channel combo delivers boutique-level tone, flexibility and fidelity in a compact, performance-ready format.

Modular All-Tube Preamp System With Expandable Tonal Range

The SYN-20IR is fortified by Synergy’s patented modular preamp platform, allowing two-channel, all-tube preamp modules to be swapped in seconds. Each module contains the authentic preamp circuitry of the amplifier it represents, using dual 12AX7 tubes to deliver genuine analog tone rather than digital modeling. When combined with the amp’s built-in American-style clean channel, the SYN-20IR functions as a three-channel tube combo capable of covering pristine cleans, classic crunch and modern high-gain saturation. With an expanding lineup of officially licensed modules, the platform offers long-term tonal growth without replacing the amplifier itself.

20W EL84 Power Section With Assignable Structure and Reactance

The SYN-20IR’s 20W EL84 power section delivers responsive tube dynamics at volumes suited for home use, studio work and live performance. The assignable Structure control provides three distinct power amp voicings, ranging from open and vintage to tight and modern, each significantly altering feel and response. Reactance further shapes the interaction between mids, highs and the phase inverter, enhancing touch sensitivity and harmonic detail. Both Structure and IR assignments can be stored per channel, allowing precise matching of power amp behavior to each sound.

Integrated Low-Latency IR Engine for Direct Recording and FOH

A dedicated high-speed DSP engine equips the SYN-20IR with impulse response processing under 1ms of latency, preserving the immediacy of a miked cabinet. Four onboard IR slots can be assigned per channel, with support for user-loaded IRs alongside the included professionally captured library via the Synergy Editor software. Whether recording silently, practicing with headphones or running direct to front of house, the amp delivers consistent, natural cabinet tones without external load boxes or speaker simulators.

Celestion Vintage 30 and Pro-Level Connectivity

A Celestion Vintage 30 anchors the combo with its focused midrange, tight low end and clear high-frequency detail, complementing both vintage-inspired and modern high-gain tones. Connectivity includes a transparent series effects loop, balanced XLR output with ground lift, headphone output with dedicated level control and multiple speaker outputs for flexible rig configurations. Housed in a Baltic birch cabinet with road-ready steel construction and universal voltage support, the SYN-20IR is built for dependable performance in any environment.

A Modular Tube Combo Designed to Evolve With Your Rig

Available in an array of colors, the Synergy SYN-20IR stands as a forward-thinking tube amplifier that combines real analog tone with modern control and unmatched flexibility. Its modular preamp ecosystem, assignable power amp voicing and studio-grade IR integration allow it to replace entire amp collections while remaining compact and portable. Designed for players who demand authenticity, adaptability and long-term value, the SYN-20IR is not just an amplifier but a scalable tonal platform built to grow alongside your music.
