Anyone using Maxxbass on the master nowadays?

Any particular reason as to why not? I mean obviously you lose control over specific frequencies, but any other reason for such a strong stance on the matter? I too, have heard it could be used on the master channel, particularly to enhance low-end when people play the music over shitty sound sources.

I confess: I found it pretty handy a while ago, mastering a song with decidedly insufficient low end. Of course, I'm not a mastering engineer, so it probably sounds like shit anyway, but I thought I got it in the ballpark using Maxxbass.
 
RBass is good for kick drums in my opinion. All the other stuff gets farty in the low end. (As a track insert!)
However, I used it once for mastering, because the original kick was dull, lacked sub bass but had tons of upper bass. So I C4'd the upper lows and then hipassed the mix at 60hz, with a moderate slope, then I slapped RBass on it, set it to 32Hz and moved on with the dynamics of the whole track. The result was punchy, clear and even lowend.

That's one of the specific uses that you can give it, although I wouldn't consider it an usual mastering plugin.
 
I ask cause there was a thread on the sturgis forum of a pic of him doing it a whiile back. However some people agreed it's not a bad thing many producers in fact do this. Timislegend was one of em and I think I've gotten really good advice from his posts in the past.
 
I can't recall him ever mentioning using maxxbass on the master bus. In fact I've only seen him mention he used it on kick and toms (and that was a while back)

I think the a lot certain people commit when looking at Joey's development - which is significantly more public because it's documented all over this forum - is taking everything to heart and being either too critical, or too "naive" for lack of better words... even if he ever did, that doesn't mean people shouldn't be critical. Ultimately, shoot it out on your 2-bus, then upload the clips if your really don't trust your ears.
 
Maxx Bass can be used to increase the bass of a track or an entire mix, but I do not use it that way. I have NEVER used it for added bass.

I will use it if I am too bass heavy and I need to replace some of the bass, yet still get relatively the same low end feel with bass harmonic tones. It does a damn good job from what my ears tell me. I always use it to remove some of the very low end frequencies and replace them with harmonics that give the low bass feel but don't flub out cheaper speakers not capable of outputting such low bass clearly.

IMHO it's one hell of a plug in.
