thanks for the input people. i try to keep my own unique style in each track so i will work with the "harsh" noises, but i don't feel comfortable removing them as this is the basis for that part of the track. i always appreciate everyone's critique and take things on board, but with this one i think i may just have to play around with it rather than totally change it. the harshness of the noise was what i wanted and i was going for a particular vibe - i will work on blending it better
cheers guys.
