Avantone Pro announces the GTR-100, a two-channel Class A/B power amplifier engineered specifically for guitarists using modern amp modelers and effects processors. Designed to faithfully translate carefully crafted tones from guitar modelers to the stage, the GTR-100 delivers high-headroom, transparent amplification without the coloration, weight, or maintenance demands of traditional tube rigs.
At the core of the GTR-100 is a solid-state Class A/B topology that delivers clean amplification that preserves the integrity of modeler-based tones while providing substantial output power — up to 140 watts per channel (4 Ω) or 245 watts in bridged mono mode (8 Ω). Switchable Line and Inst (instrument) inputs ensure optimal impedance matching whether connecting directly to a modeler, pedalboard, or standalone stompbox.
“The GTR-100 was designed for players who have fully embraced modern modeling platforms but still need reliable, high-performance stage amplification,” says Avantone Pro’s Seth Berman. “It delivers the power and clarity required for live performance while maintaining the exact tonal characteristics users have dialed in.”
Transparent power, flexible integration
The GTR-100 is built to integrate seamlessly into contemporary guitar rigs. Its stereo inputs and outputs allow players to bring stereo effects like delays and modulation into live performance environments. A switchable 4-band EQ provides precise tonal shaping to adapt to varying venues, while independent channel Volume controls offer granular output balancing.
For direct connectivity, the GTR-100 includes XLR THRU outputs with optional analog Cab Sim (cabinet simulation), enabling users to send a polished, mix-ready signal directly to front-of-house systems or recording devices — eliminating the need for microphone placement on speaker cabinets. A comprehensive 14-stage input/output metering system provides clear visual feedback for gain staging and signal integrity.
Built for the road
Housed in a compact and lightweight 1U rackmount chassis, the GTR-100 is engineered for durability and portability. Reinforced metal handles extend beyond the front panel controls, helping protect knobs and switches during transport. Rear-mounted rack rails simplify cable management in touring rigs, while a low-noise cooling fan ensures reliable thermal performance without introducing unwanted noise.
Additional protection circuitry is indicated via front-panel LEDs, alerting users to conditions that could potentially impact the amplifier or connected speakers — providing peace of mind in demanding live environments.
