Manufacturer's Description for Planet Waves PWSH01 Screeching Halt Soundhole Plug
Feedback is a major problem caused by a variety of sources, including microphone placement and overdriven PAs and amps. The problem is particularly common when electrifying the acoustic guitar. In order to hear the instrument properly in a band context, the guitarist must increase the volume sometimes to the dismay of the other members. Accordingly, Planet Waves has introduced a feedback remedy for acoustic guitars: the Screeching Halt.
Install the Planet Waves Screeching Halt sound hole cover, and users will immediately react to the increased volume before feedback of most acoustic and acoustic/electric guitars. The Screeching Halt, besides banishing feedback, incorporates features that position the unit ahead of anything on the market.
The Planet Waves Screeching Halt sound hole cover incorporates a flexible design that promotes quick installation. A special tapered contour allows for a tight, custom fit without endless adjustments. In fact, the Screeching Halt will adapt rapidly to most guitars, allowing the player to crank the volume. The cover will also adapt to most pickup systems without disrupting placement or performance. Furthermore, the Screeching Halt cover is safe with most finishes and inlays.
Fits most standard Dreadnought and Jumbo style soundholes. Might not fit most Parlor style soundholes.
