The Fump is such a cool little tool to have that slides on and off with ease. It’s perfect for players wanting that staccato/percussive sound from their bass.
Review for Mixdown Magazine
This is a very clever and versatile device. I use on my electric bass and when plugged into an amp, I can get a wide range of mutes, I can even make is sound like a double bass.
I love this thing. It's great for getting a consistent mute effect across all strings. Normally I'd mute with my palm and pluck with my thumb but that drastically alters the feel I normally have when plucking with my fingers.
If you want your bass to thump without the hassle of taking an ugly piece of sponge or struggling taking out or put in a piece of foam every time you need to get "that sound"...this is exactly what you need. Well made, easy to use. Highly recommended.
