Fump™ Bridge-Side Dampener


Palm-muted bass tone. Minus the palm.

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:

  • Works best when string fingerboard setup has little to no radius
  • Takes only a second to slide on or off, unlike the old cut foam solution
  • Clips onto your strap or music stand when not in use
  • Has no moving parts
  • Can be inserted from top or bottom
  • Requires only a 1" (2.5 cm) of space between pickup and bridge
  • Replaceable muting materials

    Nice toy

    It is not dampening all 5 strings with the same intensity. After 10 time mounting the pad material is tending to peel off. Nice toy to have and IMHO worths the money paid.

    not bad but improvable

    I expected to be able to adjust the grip, but the screw does not serve this purpose, anyway, the gripper fails to mute all strings in a uniform manner (it has a discontinuous profile)

    Fump not so good

    Experience was fine as far as ordering and shipping time. I am a bit disappointed with the fump. It is a good idea but the dampening material is such that it doesnt evenly dampen the strings. The D string on my p-bass rings but the others are dampened. Seems like the design needs some work.

    Great product idea but unfortunately didn’t fit between the bridge and pick up on my status Bass. Therefore unusable for me
