Dude, just can it already.

What the fuck is "subbassom every song". Unless you mean "sub bass on". Sub bass brings out low frequency sound in the mix and makes it more audible. i.e. the opposite of burying.

Frank cannot play Brownstone* at all. I hear a different drum sound, now that I am looking for it after checking out a few youtube sounds, that said he isn't PLAYING it any different, just the drum setup is a different sound. Whether that his preference, his drum tech's influence or something that Axl or one of the guy's in charge of marhsalling rehearsals or sorting the mix (Tommy or Pitman respectively) prefer I couldn't say or know.

Pitman is a poor man's zig zag...

Here is a photo of a harmonica:

and here is a photo of a professional Pro Tools setup

One is vastly more complex than the other. Care to guess which. Let's look at the CVs of Zig Zag and Pitman:

Zig Zag has done the odd harmonica or piano recording for some musicians and been a touring hand for others.

Christ Pitman has:
Lusk - Recording, production, mixing, mastering, lead vocals, multi-instrumentation in this Grammy-nominated band in 1996-97.
Tool - In 1994/95, Pitman toured with them and, in 1996, played synths on the song "Third Eye".

Two notable mentions from a production, sound engineering and performance POV. From a purely technically POV:

"Pitman has also done sound design and electronic work for Arturia software synthesizers, A Designs Audio [Peter Montessi], Waves Plugins, Waldorf Synthesizers, Apple's Logic Audio, Digidesign Plugins, Moog Synthesizers, Celemony's Melodyne, Ableton Live, Roland USA, Korg Music, Serge Synthesis [SMS], PlanB Synthesis [Peter Grenader], [Axel Hartmann] Neuron Synthesis, and Symbolic Sounds Kyma, Mandala Drums, Steven Slate Drums, Native Instruments."

In short the guy knows his shit and is a much more valuable asset than a harmonica player.

I'm sorry to crap on your memories of 1991 and I can understand why the old band has a special place for you... 

But I can't understand why you hate some of these old guys with such a passion, and your dismissal of what they could bring to the table is uninformed. I'm getting pretty tired of having to read this dumb fanboy shit about how awful these guys are and "how amazing it would be if Slash told Fortus to sit the fuck down, and produced the fabled VR album that never was from his back pocket and if Axl just came over it in an instant." It's just stupid.
