Record Cranked Tube Tones at Whisper-quiet Levels

Get to know them!

Suhr’s Reactive Load Box is a simple and silent solution for any guitarist looking to cut out the cabinet from their recording amplifier rig. This device replaces your amplifier’s speaker load with a rating of 8 ohms and 100 watts, plugging directly into your amp’s output and producing both unbalanced and balanced signals to connect to your audio interface, IR-equipped devices, effects, and more. Sweetwater’s apartment-dwelling recording guitarists love how the Suhr Reactive Load box allows you to crank even the most potent 100-watt tube heads into arena-ready screaming saturation, all without making a sound — it’s a perfect alternative for guitarists who aren’t willing to give up their tube amps but want to enjoy all the modern benefits of digital amplifier simulations! Best of all, the Suhr Reactive Load box is masterfully engineered to deliver the same tone, response, and even feel of playing through a traditional amplifier cabinet.

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, resulting in an exact emulation of a traditional amp-into-cab playing experience. 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 your favorite IRs and 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.
