Gruv Gear Fump Bridge-Side String Dampener (4-5 String Bass, Black)

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 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." A few things to note:

Fump is a bass string dampener that helps recreate the classic muted bass tones heard on countless vintage recordings.

Think Motown, classic soul, vintage country, old-school rock, reggae, and jazz. Fump gives your bass a warm, punchy "thump" with a shorter note decay that sits beautifully in a mix.

Palm muting sounds great, but it takes technique and consistency. Fump gives you that same vintage-inspired character instantly, so you can focus on playing instead of constantly managing your muting hand.

Any song that calls for a tighter, more staccato bass sound. It's especially popular with players chasing vintage tones or looking for a more controlled low end.
