Get to know them!

Does your guitar rig contain lots of cables? Does your pedalboard include lots of true-bypass pedals? If these situations are familiar, you're likely suffering from major-league signal degradation. That's why you need the Suhr Buffer. Boasting audiophile-grade op-amps and a glass epoxy-printed circuit board, this must-have tone tool offers a serious investment in tone. The Suhr Buffer is remarkably transparent, employing unity buffering to reverse the capacitance issues inherent in long cable runs without affecting your instrument's tone or output level. You also get a dedicated transformer-isolated output to eliminate ground looping and a polarity-reverse button to keep your signal in phase when splitting between two amplifiers. Flaunting a near-bulletproof, machined billet-aluminum enclosure, the Suhr Buffer is a dead-simple way to bolster your guitar rig for the utmost in signal integrity, roadworthy reliability, and — above all — killer tone.

Preserves your tone with the utmost transparency

Long cable runs and signal chains with an abundance of true-bypass pedals are a recipe for the capacitance issues that lead to signal degradation. The Suhr Buffer is a line driver that employs unity buffering to reverse the effects of capacitance. And thanks to its low-noise, audiophile-grade op-amps and glass epoxy-printed circuit board, it bolsters your signal without affecting your instrument's tone or your overall output level. Sweetwater guitarists have found that placing the Suhr Buffer at the beginning of your signal chain is a surefire way to maximize the sound of your guitar setup*.

Chock-full of essential features

The Suhr Buffer is a veritable Swiss Army knife for your guitar rig. For starters, in addition to a standard output, it also includes a transformer-isolated output to eliminate ground-loop noise — a common occurrence with multiple-amp setups, 4-cable configurations, and other complex guitar systems. You also get a polarity-reverse function to keep your signal in phase when splitting between two amplifiers. The Suhr Buffer is an indispensable problem-solving device that belongs in every guitarist's toolbox.

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.

Suhr Buffer Features:

  • Resolves capacitance issues caused by long cable runs with an overabundance of true-bypass pedals
  • Audiophile-grade op-amps and a glass epoxy-printed circuit board offer incredibly transparent performance
  • Dedicated transformer-isolated output eliminates ground-loop noise
  • Polarity-reverse button keeps your signal in phase when splitting between two amplifiers
  • Near-bulletproof, machined billet-aluminum enclosure
  • An easy way to bolster your guitar rig's signal integrity, reliability, and tone

*Note: If you have vintage-style fuzz pedals, such as a Fuzz Face or a Tone Bender, in your pedal chain, we recommend that you place the Suhr Buffer after those devices to retain their full sonic character.
