Thanks for the ideas. I'm not using any tone prints. The amp sounds fine without them. Please LMK how it went tonight with the flats. They maybe the ticket for me. I'm also curious about your bass settings too!
Notes on the rehearsal:
I got the Mercalli back from the shop where he installed a bone nut. After playing it some at home and listening to it with the GHS Precision Flats, I did a last minute swap and put a year old set of Chromes on it. The GHS's I had on it are closer in tone to the LaBellas on my P-Bass (which is good) but it's not what I needed from this bass. Note: I had to ream out the bridge a little as the Chromes have that unnecessarily large winding at the ball end, even with the silks removed.
Usually, I take at least 2 (when possible, 3) basses everywhere: a P5 w/Labellas and (lately) the Mercalli w/Circle K's. But I have a gig coming up that is extremely space limited and set-up time is tight, so I need to cover as much sonic ground as possible using only 1 bass, realizing full well that I would have to compromise on both ends.
It is a great combo for me. For the blues tunes that needed a P/flats sound, I rolled the blend forward (obviously) and rolled off the tone a little less than half or so. It's not quite as awesome a P tone as my regular P, as it seems a bit more 'modern', but it was definitely close enough to what I was after. Favoring the bridge pickup a hair and dialing up the tone gave me a good, aggressive tone for the more rock songs. The bridge pickup only with tone rolled off just a bit (and a little 'air' effect) worked enough for the stuff I would usually do on a fretless.
So I think this bass is keeping the Chromes. It's plenty versatile and covered everything it need to cover well enough. My first choice will always be to bring 2, but I'll have no worries with this for those room-for-1-bass-only gigs.
Amp was a rehearsal-studio-provided Ampeg 450h
Hopefully there is some useful info in all this gibberish...
People dig its funky looks too.
