The cutoff1/... knob of my just recently second-hand bought virus rack is irritatingly loose. But I don?t need any of the knobs now. I now control almost all of my eguipment with novation remote25 (and still of course use my RM1X which I will marry one day

). The knob is so loose that it doesn?t work almost at all. But I got it really (I mean really really) cheap

. 500$
