Synergy SYN-20IR 1x12" Combo Amp

Short Description:

20-watt, 1x12" all-tube modular combo amplifier featuring built-in IR cabinet simulation and Celestion V30 speaker.

What We Think:

Assembled in the USA, the Synergy SYN-20IR Combo is a 20-watt, 1x12" all-tube modular amplifier loaded with a Celestion Vintage 30 speaker and constructed from solid Baltic birch. Driven by two EL84 power tubes and two 12AX7 preamp tubes, it pairs a built-in vintage American-style clean channel with an interchangeable module dock for expanding into high-gain territory. Modern flexibility comes via integrated low-latency IR cabinet simulation with four programmable presets per channel, cab-less silent recording capabilities, a dynamic Reactance presence control, and a 3-position Power Amp Structure switch (Modes A, B, and C) to tailor negative feedback and phase inverter response. Complete with full MIDI integration, an ultra-transparent series FX loop, balanced XLR out, and software editor support, it offers a versatile bridge between traditional tube tone and modern stage or studio workflows.

Note: Preamp modules sold separately. 

Manufacturer Description:

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 1×12” Combo Amp 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 1×12” COMBO AMP.

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.

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.
