PRODUCT DESCRIPTION
- Modular valve tone platform The SYN-20IR Combo uses Synergy&rsquo
- s patented all-tube modular preamp platform allowing you to swap two-channel preamp modules quickly and confidently. Each module is built with real valve circuitry and voiced to capture the character response and feel of the original amplifier design. This approach lets you expand your tonal range for different guitars styles and sessions without changing your main amplifier or compromising authenticity all while keeping installation simple and repeatable every time for working players. Three-channel flexibility A dedicated vintage American-style clean channel sits alongside two channels from your chosen Synergy module creating a true three-channel amplifier in a compact combo format. This layout allows fast reliable switching between clean edge-of-breakup and high-gain sounds during rehearsals recording sessions and live performances. It&rsquo
- s an ideal solution for players who cover multiple roles or need consistent tones across varied musical situations without relying on pedals or complex external switching systems in demanding live environments. Power amp feel on demand The EL84-powered output section provides a responsive dynamic feel and is enhanced by Synergy&rsquo
- s Structure and Reactance controls. Three selectable Structure modes adjust feedback compression and overall contour helping you dial in vintage openness or modern tightness. Reactance acts like a dynamic presence control shaping mids and highs to better match your module speaker and playing style across different volumes and monitoring setups without altering the core character of the amplifier during performance and recording. IR-ready modern outputs Integrated impulse response technology allows silent practice direct recording and cab-less live use while preserving true valve feel. With assignable IRs and power amp structures per channel sounds can be recalled instantly via MIDI. Combined with XLR DI and headphone outputs the SYN-20IR Combo fits easily into modern studio home and stage rigs without extra hardware making it suitable for gigging in any environment. It offers the consistency and reliability that are essential for professional players.
