I'm not a pro but I agree that bass is fundamental for a great guitar sound; but, talking about The Black Album... the bass volume is really far lower than guitars. So I think the great guitar sound in the Black Album, come more than nothing by the great production and layers of guitars recorded and how they were put together, panned and some effects used.
In the Black Album bass is not that low...but we can say it's in the middle way between old school productions and modern production....
In that album the deep in the mix was done by the drums and the awesome ambience, but bass was fundamental too
