Gruv Gear Fump Bridge-Side Dampener

Get an instant staccato sound out of the box! The Gruv Gear Fump bridge-side dampener frees up your muting palm by sliding against the bridge of your bass.

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 Gruv Gear 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 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."

- Can be inserted from top or bottom
