Gruv gear Fump

Free your hand and discover a new path to old-school sound. The Fump is a simple muffling device that slips 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 naturally following the resounding success of our FretWraps and numerous requests from musicians like you.

If you've ever put foam under your strings to get that coveted old-school sound, with or without a mute, then try the Fump!

While we strongly encourage you to master palm muting, the Fump simply opens the door to new techniques and gives you the freedom to give it your all.
