This Synergy SYN20IR Amp Head features a 20-watt all-tube modular design powered by two EL84 power tubes and two 12AX7 preamp tubes, with a built-in vintage American-style clean channel. Driven by a 3-position Power Amp Structure switch (Modes A, B, and C) alongside a dynamic Reactance control, it provides massive tonal shaping from punchy vintage response to modern tight end. Onboard features include low-latency IR cabinet simulation with four programmable presets, cab-less silent recording capabilities, an ultra-transparent series FX loop, and full MIDI integration (up to 128 presets). Complete with a dedicated headphone output, XLR direct connection, and an included 3-button programmable MIDI footswitch, this 16.4 lb head delivers uncompromising tube warmth and modular flexibility for studio and stage use.

All-Tube Head – 20 Watts – 3-Channel Preamp Module Platform Amp – IR Equipped

The SYN-20IR utilizes Synergy’s patented all-tube modular system, allowing you to quickly and easily swap preamp modules to endlessly expand your tonal palette. The SYN-20IR is the world’s most flexible, convenient, and tonally versatile all-tube amplifier head. The amp’s built-in vintage American-style clean channel coupled two additional channels from your favorite Synergy preamp module, makes the SYN-20IR a three-channel tonal beast ideal for every player, every style, and every situation.

Each all-tube, two-channel module is equipped with dual 12AX7s and features the exact preamp circuitry as the legendary amplifier it is based on. In most cases the SYNERGY module offers more features in comparison to the amp itself. The Synergy engineering team painstakingly works with each brand partner to design modules that achieve the most accurate tonal representation of their famous amplifier model.

NEXT-LEVEL POWER AMP CONTROL

The SYN-20IR offers unique controls for STRUCTURE and REACTANCE that tailor the response of the amp’s all-analog power section. The revolutionary STRUCTURE feature optimizes the head for any channel by offering three distinct power amp configurations and feedback which are assignable to each of the amp’s channels. The STRUTURE feature significantly alters the overall contour and feel of the SYN-20IR.

There are three Structure modes to choose from:

Mode A: Balanced negative feedback for a clear yet punchy sound

Mode B: Vintage style phase inverter with relaxed mids and a bright, shimmering high end.

Mode C: Modern HiFi style phase inverter and low negative feedback resistor delivers a modern, tight feel with solid lows and a darker high end.

REACTANCE is similar to a presence knob, but with a dynamic response and variable phase inverter which simultaneously shapes the middle and treble frequencies. This powerful control helps tailor the sound to your chosen module and Structure setting.

3-BUTTON MIDI FOOTSWITCH – MIDI CONTROL

The SYN-20IR includes an easy-to-use 3-button MIDI footswitch that lets you save and access any combination of channels, amp structures and onboard IRs. With the tap of your toe, you can, for example, switch from your module’s high-gain crunch with a 4×12 IR and Structure Mode C to the amp’s onboard clean channel through a vintage 1×12 IR and the open-sounding Structure Mode A.

You can also connect external MIDI switchers and controllers, giving you access to up to 128 user-created presets. The included Synergy Editor Software makes it easy to assign and organize your presets for maximum flexibility.
