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's Description from Synergy

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.

About Manufacturer

Amplifiers are basically a planned amalgamation of transformers, transistors, capacitors and tubes that can increase the power of a given input signal. However, the care, thought and expertise put into the choosing of the actual components, and how they are assembled affects the final tone in very unique ways.

 

When a reasonable amount of care is taken, combined with a mass market sensibility for components, you wind up with a decent sounding amp ready for mass production.

 

However, when painstaking attention is given to every aspect of every frequency an amp can produce, with a specific tonal ‘goal’ in mind, and only the finest components, masterfully assembled will achieve this goal, you’ve moved into the area of ‘boutique’ amplification. This method of creating amplified sound usually costs considerably more than mass produced amps, making them sometimes out of reach for the average player.

 

Typically, when a guitar player makes the leap to a boutique amp, they are so blown away by the difference in tone they now command, that they never want to play through anything else… until they play through another brand of boutique amp… now they want that one too! But, in order to afford it, most jump ship and sell the one they had to acquire the new one.

 

Enter Synergy Amps. After many years of contemplating that very phenomenon, and having a ‘no compromise’ attitude about tone, a unique concept was born.

 

Synergy module

What if we were able to get both boutique amp builders and popular mass amp builders alike to design their pre amp sections (which is responsible for the majority of the actual tone of their respective amplifiers) into a compact module, that would slide easily into a compact pre amp housing that we build, AND make it easily swappable with other modules? Also, make it so each module is 2 channels, easily hooks up to an existing amps effects loop, giving that amp 2 extra tube channels, and has a silent line out with cab sim for recording studios or to go straight into the mixing board at a show, eliminating the need for a bulky amp altogether…? Finally, make the price point so that anyone could afford it! 

Well, that’s exactly what we did. And the idea is taking the industry by storm! Imagine the possibilities!

 

The player who though they just couldn’t afford a boutique amp now can!

The traveling musician that constantly worries about the quality of the backline amp he’ll have to use…problem solved!

The recording studio that would love to have all the best amps available to them. Or the home studio, that wants the same, but needs to keep the process ‘silent’.

We’ve taken every possible challenge scenario a guitar player might face, and built the solutions into the Synergy line. We invite you to plug in and be amazed like the rest of us!
