Hey Shaz, thanks for the crits - just speaked a listen to your track at work - its awesome! Will do a full review on it tonight;-)
Re the buzz and hums on my take, the guitar I had to use had to be held in one position with the guitar lead held secure against my leg otherwise that buzz went all of the time -very nasty.... yeah it drifts in and out and you can hear the response from the pickups dropping just before it happened. Excellent tone you have, mostly attributed to brilliant technique, that a strat you use? What pups you got?
