Chris, were you running it into the front end of the AI so you could use the EQ, or straight into the power amp (which could be done either without the tube stage, i.e. from the direct out, or with the tube stage, from the line out)? If the former, I know that you said you didn't hear a big degradation in the sound of the TD-100, but it's also a situation where I imagine one would be just as well off plugging straight into the AI.
I was running an XLR out into the XLR in on the front of the AI preamp, so I could use both the Tubey goodness knob and the variable impedance. When I tried it straight into the FX return, there were too many highs, mids, and string noise to be usable for me.
Having played both of our basses, it all kind of makes sense. Your bass sounds fat, dark, and punchy in the low mids, with a ton of old school 200hz-ish KAPOW (please pardon my technical jargon) to each note. The sustain dies away quickly as compared to the initial attack. My bass is leaner sounding, brighter, and more articulate with looooooong sustain that doesn't get overshadowed by the attack. The KAPOW ZONE on Tereza (that's my girl!) is more in the 800-1000 hz range, making her sound more like a modern girl (makes sense, since she's only about 8 years old); when combined with the tubey goodness knob straight into the FX return, it sounds like Ron Carter in "State of the Tenor", and I'm left with no EQ options to darken it with.
One thing about all this stuff, and something that's been discussed at length on the BG side, is that these gadgets are for a particular thing and you start getting into trouble when you ask too much of them. So, for example, when people rave about using the U5 as a preamp but complain about it not having a flexible enough EQ section, the answer of course is that it's a direct box and should be used as such. Same thing for the TD-100; I'm using it because I just want a super high-quality sound going into my amplifier, and to me the sound quality is in a different league from what any intergrated amplifier has given me (same experience as I had with the U5). I like EQ options, of course, but for DB I guess I've been fairly happy foregoing them. At that gig Chris heard (the one I posted the recording from), I would have thought from the stage that there was way too much bass going on, but apparently it sounded fine. At another gig with the same rig, I thought there wasn't nearly enough low end and I would have been cranking it up had I the option, but afterwards a fellow bassist gushed about the perfectness of he amplified sound.
And for what you're going for, it *was* perfect. OTOH, if I played my bass my way and that sound came out, I'd start freaking out! It's kind of like personal preferences driving different cars. To me, your bass feels like a Cadillac (one of the old ones that were really good and plush). Turn the wheel on it, and it makes a beautiful, smooth, swooping turn that feels solid as a mother****** and doesn't spill anybody's drink. It's also got a ****load of power, always plenty in reserve. My bass, by comparison, feels extremely tight, like a hotrodded Honda that sits about 5 inches off the ground. The ride (feel) is stiff and kind of bumpy, reproducing every single thing (road noise) that I do immediately; the tradeoff is that if you even look at the wheel sideways, the car swerves instantly in that direction. (...and my wife gets a face full of the coffee that she unfortunately raised to her lips at that moment, and I get back in the doghouse.

) Seriosuly, though, I *like* the feeling of being 5 inches off the ground with a stiff suspension and no power steering and being able to stop and/or turn on a dime.
Our strings and string heights are very similar (spiros/dominants, at about the same height), but the basses feel completely different, which is as it should be. I'm also extra glad I don't have your expensive tastes in either (analogical)cars or basses, since I couldn't afford either.
All of that to say that I loved the sound of what the TD 100 did to your bass, but for my bass it just seemed to add a lot of stuff that I usually try to tone down anyway.
I guess I'm regarding it as another point in the line of just getting quality gear (get a bass, settle on some strings, settle on an amp) and then making the tone happen with the fingers. I always felt like whatever amp I was using was impeding me in doing this, but I don't feel like that with the Summit (and I didn't feel like that with the U5).
I hear you. It's a whole can of worms, but what i notice is that pickups that are faithful to the original sound (I think the FC is pretty faithful) sound great at lower volumes. As they are amplified louder, though, certain frequencies tend to get out of balance - namely the gooey lows and the glassy string noise of the highs. In other words, if you sit up close to my bass, you'll hear booming lows and crisp string noise allong with the "meat" of the sound. Step back a few feet, and those things attenuate. 15' away, and you're pretty much hearing mostly the "meat" or "heart" of the sound. I want to have the EQ options to tame the stuff that doesn't sound natural to me as the volume goes up. Maybe I coulda done that with the Summit, but i couldn't find the range on the gigs i played. I was actually kind of relieved not to be gassing for another expensive gadget!
And down the road, if I want to slap some EQ on the other end of it, I can do so and still be under half the price of an AI Focus. I also have this thing that just came in the mail last week, a Read Purity tube preamp, and from my initial fiddling it sounds better than the Summit Audio gear and has a Jensen DI and an EQ section as well, so who knows, that may be the best of both worlds.
Looking forward to hearing you on it!
Chris, I do think you would enjoy the U5; there's certainly nothing remotely tube-y about it, and between the six presets and the high-cut filter you can get a lot of goodness out of it. Until the Summit came along, the U5 had set the bar for me, and the difference between the two units is really one of preference and not of a difference in quality.
I'm looking forward to trying one. I may be able to review one for the BG mag articles. If I do, you can count on me sharing in a very verbose manner.
