IMHO, this head doesn't punch at all. It wallops. That's a characteristic I associate with the db750 and many other tubey heads. It has gobs of wallop under the hood. Glorious sounding solo and for those who want that kind of thing in a band mix. I don't. The Shuttle 9 to me starts off tight, and then I can add some wallop at my choosing, which is the approach I prefer over this.
I'm not afraid to cut bass either. I had the bass COMPLETELY off, hoping that it would accentuate the upper mids a bit more. It didn't really work. I also cut lower mids at 220, which helped a little, but the end result still wasn't quite what I was after.
Also, I'll agree that this tone works better with a P bass. I play a 55-02 mostly, in the jazz mode setting, and it's just too deep sounding to get the clarity I'm after. I love that fret buzz and grind when I slide on notes, but it just doesn't come through in the way I want it to, which is probably WAY more distinct than what most folks would want, especially those who are used to all-tube heads.
Again, I'm really saddened because I love the way this thing sounds as I just sit here in front of it. With the AE212, it moves massive amounts of air and it just gives me goose bumps. I felt this way about the db750 on a db410, but gosh did I ever hate that head on a gig. Only time I ever liked it was outdoors on a wide open stage with no walls or structures anywhere around.
I honestly don't think I need to wait for a gig to know for sure on this. This head just isn't for me. I'm happy for Genz however, and for all the users who are finally going to get this kind of voicing and feel in a small and light package.
