Gruv Gear Fump Bridge-Side Dampener / Muter with No Palm Pressure & Instant Mounting for 4-5 String Electric Bass Guitar - Short, Crisp Notes for Old-School Tone - Black - Pack of 1

Free up your muting palm and discover a new path to the old school. The Fump is a simple muting device that slides over the strings against the bridge of your 4- or 5-string electric bass to instantly recreate that sweet staccato sound - without using your palm! The Fump was born as a natural step following the wild success of our FretWraps, and from numerous requests from players like you. If you've ever stuffed foam under the strings to try to achieve that coveted "old school" muted or upright-like tone, then you might give the Fump a try! While we definitely encourage mastering proper palm muting, the Fump simply opens up possibilities to discover new techniques and gives your hands the freedom to "dig in."

Perfect for 4- and 5-string electric bass guitars, this bass mute delivers crisp staccato notes—no palm muting required. A great alternative to DIY foam tricks, it fits securely near the bass guitar bridge and ensures clean, consistent muting every time. Upgrade your tone the smart way.
