The Synergy SYN-20IR 20W tube guitar amp head delivers unparalleled flexibility by combining Synergy’s all-tube modular preamp system with built-in impulse response (IR) technology. Designed for musicians who demand tonal versatility, this amp allows players to swap Synergy preamp modules, each based on legendary amplifier circuits. The built-in clean channel, combined with two additional module channels, creates a fully functional three-channel amp capable of handling any playing style. Whether you're recording, rehearsing, or performing, the SYN-20IR offers studio-grade sound with modern connectivity.
Revolutionary Preamp Module System
The SYN-20IR integrates Synergy’s modular all-tube preamp system, giving players access to officially licensed recreations of classic amplifier circuits. Each module features dual 12AX7 tubes and accurately replicates the tone and feel of its original amplifier counterpart. With an ever-expanding list of modules from industry-leading brands like Friedman, Soldano, Diezel, and more, the SYN-20IR offers limitless tonal exploration without the need for multiple amplifiers.
Selectable Power Amp Structure and Reactance Control
Unlike traditional tube amps, the SYN-20IR features a three-mode Power Amp Structure, allowing players to fine-tune the response of the EL84-driven power section. Mode A delivers balanced negative feedback for a clear and punchy tone, Mode B emulates vintage phase inverter characteristics with relaxed mids and shimmering highs, and Mode C tightens the lows and darkens the highs for a modern, high-gain response. The Reactance control dynamically adjusts presence and midrange for even greater tonal shaping.
Industry-Leading Impulse Response Technology
The SYN-20IR includes a powerful digital IR engine with under 1ms of latency, allowing players to send their signal directly to a mixing board, recording interface, or headphones. With four onboard IR slots and the ability to load custom IRs via the free Synergy Editor Software, this amp provides realistic cabinet simulation for a fully mic’d-up sound without needing a physical speaker cabinet.
Advanced Connectivity and MIDI Integration
Equipped with an XLR balanced output, an ultra-transparent FX loop, and a dedicated headphone output, the SYN-20IR is designed for both stage and studio use. The included 3-button MIDI footswitch allows for real-time switching of amp structures, IR settings, and channel selection. Additionally, the amp supports up to 128 user-programmable presets when connected to an external MIDI controller, ensuring seamless integration into any professional rig.
