The 18A0166 Rose Plug 000/00 from Martin & Co is a simple but useful accessory for any acoustic guitarist who plays amplified with 000 or 00 models. Designed to fit 3.875" diameter soundholes, this cap helps to reduce unwanted feedback that often occurs at higher volumes, particularly on stage or in the studio.

Made from a material compatible with nitrocellulose finishes, the soundhole cover can be fitted and removed without the need for tools, making it quick and easy to use before a gig or recording session.

Installation is secure and there's no risk of damaging the guitar, while effectively blocking certain resonances that cause feedback. Lightweight and discreet, it remains a practical solution for those who want to play amplified without losing control over their acoustic sound.
