Locking in & filling out - hard things in or out of BIAB.
Buy a bass, record your own bass parts. It'll sound like a guitarist playing bass for a while but you'll learn the eldritch arts of bass soon enough.
I prefer to do my own bass parts in the main because I can but also because BIAB tends to be a little too busy on the bass for my liking.
If you've a good drum groove and know what you're doing on guitar you'll know what & where to stay away from.
