Thanks for your replies guys!
As I say, it was a bit of fun, as I'm a big fan of John Sykes. It was recorded it on my home setup, which is an elderly Mac running Logic Express, using all the onboard drum samples and stuff with a POD (also pretty old!) in 'Rectified' mode. I've found a bit of low shelving and a little presence boost makes it more life-like and chunky, with less of the boom. The guitar sounds sweeter thorough a real amp though -oh, for a Boogie Studio Pre-amp..!
Cheers!
Rich.
