Recording Equipment

I was thinking of recording my own songs, and I wondered, what program/harware does GMC use for recording?
All of your recordings have very good sound quality, and the programmed backingtracks are also very good.
What program are you using for the backing, and recording? Is it the same one? Are there any other good alternatives

Thanks

Can Scales Be Used Together ?

If you for instance play a G major what scales can then be used for soloing ?
Is it every major scale wich is built on a G? For exaplme a lydian G major scale, or a pentatonic G major scale?
Can one combine different scales in a solo, or do you have to stick to just one ?


One forehand thanks =)
