All-Tube – 20 Watt – 3-Channel – Preamp Module Platform 1×12” Combo Amp – IR Equipped
The SYN-20IR 1×12” Combo Amp 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 1×12” Combo Amp 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 1×12” Combo Amp 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 1X12 COMBO 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 1X12 COMBO.
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 1×12” Combo Amp 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.
CELESTION VINTAGE-30 LOADED
Celestion’s Vintage 30 sits high among the world’s most revered electric guitar speakers. It’s vocal midrange, detailed top end, and tight lows makes it the ideal speaker for the SYN-20IR Combo amp.
SYNERGY EDITOR SOFTWARE

The included Synergy Editor Software unlocks the Syn-20-IR's 1X12 COMBO's full potential. Connecting via a standard USB jack, you can easily assign different IRs and Structure for your amp and module channels, load and organize your IR library, save up to 128 MIDI presets, and tailor your power amp simulation via the assignable Low-Pass and Low-Pass filtering. It's all available within the software's streamlined and easy to use interface.
