Planet Waves Screeching Halt

Despite impressive advances in pickup and amplification systems over the last decade or so, feedback continues to plague amplified acoustic guitarists, especially those who have to play alongside drums and electric guitars, basses and keyboards. And while there are electronic feedback eliminators out there, the new Planet Waves Screeching Halt takes a less high-tech approach. The rubbery disk fits into the sound hole of most acoustic axes, helping to tame some of the resonances that build up when the guitar interacts with onstage amps and monitors. This lets the player increase volume before feedback and allows for more flexible use of tone-shaping tools like EQ. Not bad for something that costs less than 10 bucks and fits in your case or gig bag. Planetwaves.com.
