Hi Len,
Thank you for your comments.
I multi-tracked guitars in GarageBand for Mac OS X, I use GuitarPort from Line 6 and used the setting "Son Of Privilege" for the lead distorted guitars. I programmed my own Echo sounds within Gearbox software for Mac OS X from Line 6.
The backing track I purchased from
www.ameritz.co.uk some of their tracks are very good and some are not so good, but this one is excellent.
Thank you for your time in listening to it.
Regards
Chris
