I like the clips with different basses. Trying to decide which wood combo I like best! I always felt that ash/maple basses had a lot of bite up top, but that the highest highs were rolled off - or something. Might need to listen to this recording again.
R.e. the HPF/compensation (even though it doesn't apply to the DI), forgive me if I'm being a bit dense, but we're talking about tweeter buzz with fuzz, right? AMD we want the signal to roll off some up top, like a paper cone driver would, right? I think of an HPF (like my fDeck) as rolling off stuff below a certain frequency and passing everything above it through to the amp and, ultimately, to the speakers. That would leave the bumble bees (if I'm interpreting them rightly as tweeter buzz) still buzzing around, unless the HPF is implemented in some other way and the highs are going somewhere... else. Am I missing something obvious here?
Listened to the camera clips is the new/proto BOT and the old BOT on your Youtube channel. Different recordings made at different times, so hard to say, but maybe the original is a little thicker, with a little more hair (not sure that's the right word here), and the new one is a little more clean and transparent... Possibly a bit tighter down low? Again, hard to say for sure.
The different boosts are audible... trying to extrapolate to how they'll sound and feel through a cab. I did a bit of quick and dirty recordings with some of my pres the other night, and found myself using, with headphones (and perhaps unadvisedly) levels of bass boost I'd rarely use through a cab, because they'd be huge. It'll be interesting to see how those presets translate to recording and live use.
