I would imagine so... I can't look at V Vocal for more than a few moments before I have to run away. It just looks too ugly... and it reminds me that Cakewalk needs to hire panup so that I can get a version of SONAR X that I can look at.
The idea is that even the best bass players and bass guitars have slight shifts in intonation... which is great if you are into expressive and original bass playing, but if you are using the bass as a "base" or foundation for all the other harmony in the mix then the closer it is to being right on tune, the easier it seems, to me, to mix it so it stands out without making stuff sound muddy.
All the other mix techniques mentioned are pertinent... to the extent that I take them for granted. Do all the low cuts and mud avoidance with all the other instruments... for sure, but the idea of making the bass notes them selves serve as a good reference for all the other tuning in the mix seems, to me, to make every thing so much easier.
FWIW, I have a couple nice bass guitars and a couple favorite preamps and compressors.... and that really helps make it easier too.
A lot of times, a fussy bass player will come to my place and end up playing my gear because it just gets them what they want to hear right off the bat and they remark that they are surprised because they have spent so long testing and acquiring their gear for their personal sound... and then they play one of my plain old bass guitars through a great preamp and great compressor and they kinda get a smile on their face because they quickly figure out that the sound has been in their fingers all the time.
I like watching that happen.
Then I sneak a quick tuning run and see if I can get away with that before we do the vocals. :-)
