[sigh] I swear, if the Holidays came twice a year, I'd be an orphan... my Parental Units have traded the 'whatever imported funk they got from the grandchildren' back-n-forth for a month. The Ol' Man ended up in the cardiac ward, Mom in the ER. I remain inexplicably impervious. Sure ain't from livin' right.
The FL-105 is such a cool piece of gear. I'm fascinated most by the notch filter capability. I first started using filters with just this; notch filters. I didn't even know what they were, except they were a tool I used to cut out really nasty, troublesome mids of my upright bass, and its piezoelectric/mic pickup set many years ago. The mic presented feedback problems at higher gain, but at least helped 'warm' things up a bit, but the bridge piezo element was (and still is) quacky as... well... I don't actually have a better punchline that doesn't involve waterfowl. It sounds like hell raw. But I found if you notched out those offensive upper-mid sounds, it was pretty good. And if I used a high pass filter, I could trim off some of the really fluffy sub-60hZ low end, and get more stage volume... always a struggle with places we were. Back in those days, all I had to work with was the controls on my amp, two knobs; FREQ/CUT. Later, my Acoustic Image amp had some more options. And I'm still kicking myself for selling that Rane AP-13 preamp... dumb, dumb, dumb...
So anyway, that's my interest. I'm so 'set-it-and-forget-it' that an SF-2 is basically technology wasted on me... I have the one in my home rack dialed-in where I like it, and I rarely mess with it. I know what all it does, but I'm good.
An Alembic stompbox that makes my upright bass rig work better... now I might be able to justify that. I'm not clamoring to get in on this first run, but it's definitely in my wish list of upgrades. I'm anxious to hear the reviews come in on how other folks are using them. Pretty sure my whole premise will be in a tiny minority. I may even be alone.
