This is the holy grail of rotary mixers - it really has to be heard to be believed! I used to use it to fix crappy sound systems at gigs - the bass is so rich and fat and smooth it will give you goose bumps. The first time I heard one these I though the DJ had an awesome knob! It also blends 2 tracks together incredibly well even if slightly off tempo.It kills me to sell it but I haven't played a gig in years and want it to get good use in a good studio or club.
