Many thanks for all the advice guys...
All makes sense. Think I will go the way of fitting a decent pup and ditching amplitube for the bass track and see how that goes.
I think I'm doing most other things pretty much ok...I run high pass filters on all other tracks, guitars, synth etc to make sure there is nothing fighting the bass for space.
The biggest problem I've had is that anything played on the low e is really muddy...the other strings sit in the mix fairly well but that low e is just so boomy...by the time I've taken all the boomy frequncies out there is nothing left. Hopefully a decent pup and a new set of stings will help...!!
