Synergy Amps SYN-20IR Head and JCM800 Module Bundle

SYN-20IR All Tube Head

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.

Brought to life by a 20-watt EL84 power section, the SYN-20IR is ideal for at home, in the studio, onstage, or at rehearsal. The SYN-20IR is packed with features to satisfy today’s demanding players including onboard impulse response (IR) technology with latency less than 1ms, selectable Power Amp Structure, silent playing, XLR DI and Headphone outputs and fully MIDI capability.

INDUSTRY-LEADING IR TECHNOLOGY 

The SYN-20IR boasts a powerful digital engine dedicated to its four onboard impulse responses (IR) and power amp simulation in the most accurate and natural-sounding way. Utilizing an oversized 500 MHz ARM DSP processor, it delivers these professionally captured IRs with under 1ms of latency, far surpassing competing products. Add and manage your own IR library, as well as the 13 included IRs, using the free Synergy Editor software.

SEAMLESS CAB-LESS OPERATION

The SYN-20IR allows you to safely go front of house or to your recording device with unmatched response and realism without an external speaker cabinet. Superior to passive and reactive loads, whether running direct onstage, in the studio, or even utilizing the amp’s headphone output, you always get the perfect feel and sound with zero compromises.

THE PERFECT AMP FOR EVERY SITUATION

Finding the perfect balance at 20 watts, the EL84-powered SYN-20IR is the working guitarist’s most valuable weapon. It’s designed for effortless portability while retaining rugged durability. The head’s compact size and light weight makes it easy to move between gigs, studios, or different rooms in your home. And the amp’s road worthy steel construction protects it to ensure consistent performance every time you plug in.

ASSIGN (POWER AMP) STRUCTURE and IR TO EACH CHANNEL

Right from the amp’s front panel, you can assign one of four impulse responses (IRs) and one of three POWER STUCTURES to each of the three channels. Easily manage and save it all to the included 3-button MIDI footswitch.

NEXT-LEVEL POWER AMP CONTROL

The SYN-20IR offers unique controls for STRUCTURE & 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 STRUCTURE 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 delivers a modern, tight feel with solid lows and a darker high end.

SYNERGY EDITOR SOFTWARE

The included Synergy Editor Software unlocks the SYN-20IR’s full potential. Connecting via a standard USB jack, you can easily assign different IRs and Structure settings 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.

3-BUTTON MIDI FOOTSWOTCH - 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 4x12 IR and Structure Mode C to the amp’s onboard clean channel through a vintage 1x12 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.

UNIVERSAL VOLTAGE

The SYN-20IR works seamlessly anywhere in the world with the help of a voltage selector switch found on the back panel. When traveling or moving to a different country and want to take the SYN-20IR with you, there is no need to re-bias the amp or use a step-up/step-down transformer – just select the right voltage, replace the Mains fuse with the correct rating and you’re ready to go!

Marshall JCM 800 Preamp Module

Few amplifiers have achieved the near mythic status of the Marshall JCM 800. When it first roared to life in the early 1980s, it didn’t just define an era - it ignited it. Kicking off a new generation of tones, the JCM 800 became the definitive voice of hard rock and heavy metal.

Big, aggressive, and unmistakably British. It took the foundational crunch of the Plexi and added the gain, punch, and focus that powered a generation of guitar heroes.

Marshall JCM 800 2203 (100w) and 2204 (50w) circuits, with their single channel, cascaded gain stages, and signature midrange roar, delivered a level of authority and articulation that set them apart from anything before or since. It was the perfect balance of power and precision. For countless players, the JCM 800 isn’t just an amplifier - it is the amplifier.

Now, Synergy and Marshall have teamed up once again to bring you, for the first time ever, this legend in a three-tube, dual-channel preamp module. Utilizing Marshall’s original circuit design, the JCM 800 module delivers the raw energy, attack, and articulate overdrive of the iconic vertical-input 2203/2204 amplifiers.

Whether you’re chasing the three-dimensional crunch of 80s rock or crushing tight gain for modern metal, the JCM 800 module gives you the legendary tonal experience that defined a generation.

DUAL-CHANNEL, THREE-TUBE PREAMP

Each of the JCM 800’s two identical channels feature independent Preamp, Bass, Middle, Treble, Presence, and Volume controls, giving you complete command over your gain structure and tonal response.

From dynamic low-gain crunch to saturated high-gain sustain, the JCM 800 module delivers every nuance of the original amp’s voice. Independent Master Volume controls for each channel allow you to precisely balance rhythm and lead levels with all of the amp’s dynamic character and harmonic complexity.

THREE-TUBE MODULE WITH BUILT-IN 0-WATT POWERAMP - A SYNERGY FIRST

The JCM 800 module introduces Synergy’s revolutionary three-tube architecture - a first in modular preamp design.

Beloved by generations of players, the original JCM 800 truly came alive when cranked, thanks to the magical interplay between its preamp and power amp stages. Synergy has now captured that same raw energy and unmistakable feel in a compact, modular form. Two 12AX7s drive the preamp, while a third 12AX7 powers the built-in 0-watt amplifier and phase inverter.

With the JCM 800 module you get the sag, feel, and harmonic bloom of a fully cranked JCM 800 head - at any volume. The JCM 800 module delivers the authority, grit, and edge that made this amp an icon in rock history, while propelling Synergy’s modular platform into bold new sonic territory.
