They combine the use of sound ports, brass chime pipes, intake and exhaust passages to eliminate and regulate unpleasant overtones and control feedback prior to transduction.

Los Angeles, CA (August 7, 2015) -- Keeler Sound is disrupting the music industry with a new line of Sound Processors - “The Performer Series” - to pre-process sound in both nylon and steel string acoustic guitars, eliminating the need for post-production.

Both “The Shorty” and “The Jumbo” sound processors combine the use of sound ports, brass chime pipes, intake and exhaust passages to eliminate and regulate unpleasant overtones and control feedback prior to transduction. A diaphragm unit and optional sound collector are used to enhance, accelerate, scavenge and multiply the harmonic structure of the sound wave, resulting in perfectly balanced tone. The processors can be used with or without a diaphragm and the diaphragms are available in various materials and styles – wood, carbon fiber, slotted and non-slotted.

Keeler Sound designer and engineer Rick Keeler says use of the diaphragm serves several purposes: to inject the properties from the diaphragm material into the sound wave, altering the sensitivity, equalization and compression stature. Another purpose is to capture the sound waves and reproduce them as an exact duplicate of the original, which can be amplified and transformed into acoustic or electric energy. Game Changer: Use of the Keeler Sound Processor changes the sound wave and timbre of the acoustic instrument, giving the musician flexibility to transform the overall tone and harmonics of the guitar.


  • Handcrafted from solid tone woods and high quality brass
  • Carbon fiber options
  • Brilliantly engineered to optimize sound quality and control feedback
  • Enhance tight bass focus and 100k bass roll off
  • Creates a smooth and dynamic high end register
  • Easy installation requires no tools
  • Modular design allows for customizable tone creation
  • Manufactured and assembled in California, USA

The Jumbo Keeler Sound Processor retails at $299 each; the Shorty Keeler Sound Processor retail price is $249.

"I don’t like any type of art that has to be explained."

The profoundly prolific guitarist leads his band of tricksters through a surrealist sonic exploration of deep, esoteric rhythms and intricate interplay on Thisness.

On his new album Thisness, Miles Okazaki is credited as playing guitar, voice, and robots. If you imagine that the reference to robots is some sort of artsy kitsch—like trapping a Roomba Robot Vacuum into a tight space to sample its struggles as it percussively barrels into the four walls—you’re very far off the mark. Okazaki—who has an elite academic pedigree with degrees from Harvard, Manhattan School of Music, and Julliard, and currently holds a faculty position at Princeton University (after leaving a post at the University of Michigan, to which he commuted weekly from his home in Brooklyn for eight years)—wasn’t kidding.
