Middle and upper register double-stops on a P-bass can be magical -- mids are so rich and characterful, the chords growl and change like they are alive.
hi, thnx for reply. good description. yeah, the tones do morph. some kind of compression going on. lots of colors. my double stop plucking technique is punchy but inefficient. working on it.
I had an HBP-1 800D. Below is a photo of the top of mine:

If yours is like mine, it will have that big vent across the top and a tiny, high speed fan (on the side?) with an on/off switch (in the back). There's a lot of heat-producing stuff in that 1U chassis and, in my opinion, it'll be a lot better for the amp if there's an open space above it. I don't know how deep that ART voltage meter/light-bar thing in your rack is, but if it's shallow enough to leave most of the vent unobstructed, you could try switching spots between it and the HBP. Otherwise, I think you'd be better off with a 3-space bag.
Any time you use the HPB as an amp (and not just a pre), you'll want to make sure that the fan is on (unless perhaps at low volume/recording, but even then you want to make sure that air has room to circulate). You'll want to make sure that the fan is unobstructed and that the back flap of the bag is wide open, too.
EDIT: Looking at your photo again, it looks like putting the ART on top would make reaching the controls on the Demeter a pain if the light bars were pulled out. If that's the case and you want to use the ART, I would look into a three-space rack or, if there is
some space for airflow atop the Demmie (more than is apparent in the photo), perhaps a small, additional fan set in the back of the rack would help. You could even semi-permanently install one, a couple of different ways.
