Hey PappaK.Nice! And what speakers are you using?
After trying my HPF today with the band, it was definitely an improvement - but I'm still struggling a little. You'd think with a head like the TC RH450 and all it's EQ possibilities I'd be able to really zero in on the trouble spots. The head sounds really wonderful with my P-Basses, but I'm starting to really doubt it for my upright needs/wants. Aargh. Frustrating.
Of course, now I'm starting to look at other possibilities - with maybe a simpler EQ setup - but geared for upright bass. I know I can get a very decent P-Bass tone out of pretty much any amp, so I'm not too worried in that department.
Man, there have been so many posts in this thread since my bleary eyed ones < 24 hour ago.
But, since you asked ...
Mostly a Euphonic Audio Wizzy M-line (1x12). On loud gigs (for me), I add a regular Wizzy 1x12.Nice! And what speakers are you using?
FWIW ... I run the EQ flat on my AI Focus for upright. The only adjustment I make (and tweak very slightly) from gig to gig and room to room is the roll-off frequency for the high pass filter, and for the pickup mostly. That said, my gigs are largely unremarkable. Check my profile if you like.Of course, now I'm starting to look at other possibilities - with maybe a simpler EQ setup - but geared for upright bass.

I think so much of the feedback thing has to do with where you are located relative to your speaker, and monitors (if present). I can recall one gig where I was pinned in and could not move around, but just spinning the bass on the endpin a bit away from the speaker changed the sound. Again, this was no high profile gig. Just a club. FWIW, YMMV, ...
P.S. I use the same rig, no high pass filter, with my Lakland Bob Glaub and Lakland Joe Osborne. Flatwounds. Old school.
The M-line just handles the low-mids that I crave so well.
