ooh the air fx sounds nasty - you put a track through it and it instantly sounds like a shit mp3.. i could never use one of those ****ers..

i have an electrix eq killer which is about the best sounding kill i have ever heard, its got 3 bands and 2 sweeps which sound awesome.. I must say this is one of my very favoutite toys in the studio :love:

also the elextrix mo-fx is a cool toy too - used to have one of those..
the electrix filter queen and filter factory are ok bu i dont think they cut the mustard next to an akai mfc42 or better than that a sherman.

i had a red XS-FX too, which, like the mo-fx took a little time to really master but was well worth it.. sound quality wasnt as good as the mofx though.
sherman filterbank 2 is allways a goodun too - but just watch you dont blow the fu*kin pa up

if i was a dj i would just go buy a pioneer djm-600 - the fx on there are pretty neat and piss easy to get your head round.
