The only tip I can really give you is to check that your eq is ok, then crank the amp quite a bit - to 6 or above on the master. Does your amp sound fine just being listened to, and in the recording it sounds bad? If that is the case then your multitrack might just not be very good. I'm a bit confused by your question. Can you get the sound you want before you start recording? Or are you not able to get the tone you want at all?
