Cranked Amp Tones Without Making a Sound
Building upon Suhr’s highly regarded Reactive Load unit, the 8-ohm, 150-watt Suhr Reactive Load I.R. box upgrades the formula with a host of improved controls and powerful impulse response capabilities. Just like original, this device starts off with Suhr’s masterful reactive load technology, replacing your amp’s speaker load and allowing you to silently send your amp’s output straight into your audio interface, to the front-of-house engineer, or even your headphones. However, instead of relying on your amp’s raw signal, the Reactive Load I.R. comes equipped with 16 Suhr speaker cab impulse responses to add space, dimension, and an ultra-realistic edge to your direct tones. Plus, the Reactive Load I.R. also boasts a USB port to accommodate your preferred 3rd-party impulse responses. You also get an aux-in for silent jamming to your favorite tunes, a screen to navigate your impulse response, a 6dB signal boost for low-wattage amps, and a Hi-cut switch for sonic sculpting. Simply put, the Suhr Reactive Load I.R. is a superb all-in-one solution for the volume-concerned guitarist who requires uncompromisingly authentic cranked amp tones.

16 Celestion-captured IRs onboard
Right out of the gate, the Suhr Reactive Load I.R. boasts 16 Suhr amplifier cabinet impulse responses, exquisitely captured by Celestion. These impulse responses instantly breathe life, dimension, and sonic depth into your amp’s raw direct signal. Furthermore, the Reactive Load I.R.’s USB jack allows you to upload your favorite 3rd-party IRs, and navigation is a breeze thanks to this device’s easy-to-navigate onboard screen. Lastly, much to the pleasure of Sweetwater’s recording guitarists, the Reactive Load I.R. can send both your IR-equipped signal and dry signal simultaneously for the utmost mixing flexibility.


Reactive design provides pure transparency
Designing a speaker load box that doesn’t color your tone is no easy task. But, as always, Suhr comes through with simply unparalleled sonics and masterful engineering. How does it work? While many speaker load boxes sport a fixed resistance across the full frequency spectrum, this reactive load box provides a far more dynamic operation that’s tuned to function just like a physical speaker. The result is an exceptionally transparent and organic-sounding tone, ready to be paired with the Reactive Load I.R.'s onboard suite of Suhr cab sims for studio-grade tones at whisper-quiet volumes.
Suhr: the pinnacle of craftsmanship, playability, and tone
Suhr doesn’t just build handcrafted, boutique-quality instruments and amplifiers — the company creates exceptional tools that fuel musical dreams and artistic passions. John Suhr began crafting custom guitars in the mid-1970s, and by the dawn of the 1980s, he was building made-to-order Pensa-Suhr instruments for a who’s who of top musicians. In the 1990s, John collaborated with celebrated rig builder Bob Bradshaw to design the now-legendary CAA 3+ and 3+SE preamps and the CAA OD-100 amplifier. In 1997, after a stint as senior master builder for Fender’s Custom Shop, John founded his own company, a decision that enabled him to bring to fruition products of unrivaled quality, detail, and craftsmanship. Today, the Suhr name is synonymous with prestige; a guitar, bass, or amplifier with the Suhr marque garners instant respect. With elite players such as Mateus Asato, Reb Beach, Scott Henderson, James Norbert Ivanyi, Andre Nieri, Pete Thorn, Ian Thornley, Doug Aldrich, and Andy Wood on the company’s roster, you can be certain that your Suhr places you in esteemed company.
