Whether you use speaker isolators or not is a question best left with studio engineers and experts who work in the audio industry. When it comes to guitarists, most of us don’t really have the time or energy to explore this option when it comes to our own guitar amps, but the general consensus has long been that the concept works.

IsoAcoustics, who have been manufacturing isolation products for pro audio, live sound, radio and television, and consumer markets, just released the IsoAcoustics Stage 1 Board (with integrated isolators) aimed at guitarists and bassists, which provides a portable isolated platform that decouples stage monitors, sub woofers, guitar and bass amps from the stage or floor to improve sound clarity, tighten up bass response, and generate more natural spatial sound reflections.

Paul Riario

Paul Riario has been the tech/gear editor and online video presence for Guitar World for over 25 years. Paul is one of the few gear editors who has actually played and owned nearly all the original gear that most guitarists wax poetically about, and has survived this long by knowing every useless musical tidbit of classic rock, new wave, hair metal, grunge, and alternative genres. When Paul is not riding his road bike at any given moment, he remains a working musician, playing in two bands called SuperTrans Am and Radio Nashville.
