Manufacturer's ID: SYN-20IR Combo
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.
Brought to life by a 20-watt EL84 power section, the SYN-20IR 1x12” Combo Amp is ideal for at home, in the studio, onstage, or at rehearsal. The SYN-20IR 1x12” Combo Amp 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.
MODULES BASED ON LEGENDARY AMP MODELS
Synergy offers an ever-growing list of all-tube modules based on legendary amp models which include everything from IIC+ crunch and AC-style chime to BMAN bloom and even Steve Vai's signature leads. This allows the SYN-20IR 1x12” Combo Amp to offer unparalleled versatility and tonal exploration.
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
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.
INDUSTRY-LEADING IR TECHNOLOGY
