Transform Your Amp’s Output Jack into a Transformer Isolated Signal
The Suhr ISO Line Out box represents a simple, straightforward, and versatile way to experiment with expansive wet/dry rigs or feed your effects processor with a separate line-level signal. Plug your amplifier’s output jack into the Suhr ISO Line Out box to convert its signal into a transformer-isolated signal. It can then be sent to another amplifier’s effects loop return or even a separate power amplifier with speakers. This box’s line-out jack comes wired for both balanced and unbalanced connections, with a built-in phase switch and a ground reference switch (strictly applicable to balanced cables) to reference the device’s ground to the line-out cable ground. From masterfully crafted instruments to amplifiers, utility devices, and beyond, Suhr’s products never fail to impress when they come through Sweetwater’s doors.
Note: The Suhr ISO Line Out Box is not a load box; your amplifier will still need to be connected to a speaker load when the device is plugged in. For advice on picking out a load box, make sure to reach out to your Sweetwater Sales Engineer at (800) 222-4700.

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.
