Used, but generally in good condition as seen in the photos. Note, these are NOT sticky. All have been properly cleaned and do not have the sticky, gross feeling that's typical for the knobs on this unit. This will fit the Minbrute or the Microbrute (and perhaps the Matrixbrute, but I have not confirmed this).  

Including a photo of the synth for reference. This listing is for the knob(s) only. If you need to purchase a bunch of these, message me and we can work out a better price. 

If you need a part for the Arturia Minibrute, but do not see it listed, please message me :)
