Ken,
I was reading a back-and-forth about how amps shouldn't really be thought of as serving particular instruments (i.e., whether there such a thing as 'J bass amp' or a 'P bass amp'). Seems like you seem to favor your J with the F1/AE212 and your P with the STM900/AE410. Do you think one could be well served by pairing the STM900 with the AE212? Or does the 'bigger/DB750-ish' low end of the STM900 need the tighter AE410 to balance (I've read you guys think the AE212 is really kind of more flat sounding than the AE410, and thus might be too 'big' down low for some heads).
I'd like to have just one head and one cab, but be able to deliver quick tones for funk/slap J stuff, and more tubey tones for when my p bass gig comes calling...
It gets down to personal opinion and tone goals. If you are one who would always dig a big, fat warm, round tone (the Paul Turner thing), then many would be totally comfortable with the Streamliner as their primary amp. For me, that wouldn't work, since I like the tight/bright thing on occasion, especially with a 70's style J that kind of is voiced for that kind of thing, and just like an SVT or DB750 or whatever, the Streamliner is just not voiced for that.
It again doesn't really have to do with 'matching a bass to an amp' at all, but rather involves the idea of a kind of 'all tube thing' versus a more 'solid state thing'. If you are the type of player who craves an 'all tube tone', or a tone on the extreme tube side of the hybrid thing, the Streamliner would most likely float your boat as your primary head. For me, it is a 'different enough' tone that I am only happy with it for a certain vibe.
With me, it is more of a wonderful match with what I consider a more hip hop/neo funk type tone, which seems to be driven by a fat, somewhat vintage tube/P Bass combination. So, again, this has nothing to do with having a specific amp for a specific type of bass, but rather having a rig that really works to derive a particular tone.
As a side note, I'm with JimmyM (i.e., all his comments on mic'ing his SVT rig to 'get that tone to the board') on the DI thing with this particular rig/bass combination. With this amp and tone settings, etc., running a DI to the board would in no way provide the tone of the rig. It would be way too bright and clanky. Mic'ing would be key, or having a DI lke the Reddi which could mimic that super fat, warm tone. Post DI would probably not work either (in a live situation), since there is quite a bit of EQ involved to really make the whole thing work on stage.
Regarding the AE212, just like I would not enjoy a DB750 with a wide, smooth cab like a 410UL or an AE212, I would have zero interest using the Streamliner with cabs like that (HT112ER, 410UL, AE212... again, personal tone goals there).
I will say again, the best way to achieve success with this amp is to think of it as an all tube amp (or a DB750 or MPulse600). That is its vibe, and the cabs that all the tube amp and DB750 guys post as working great with those type of heads work very well with the Streamliner. This is a huge positive for me... think about it, finally a micro that really does kind of behave like an all tube amp (or DB750).... for many that has been a dream.... for some, it will be a nightmare if you don't understand the dynamic between an all tube amp and a cab (or again, the DB750).
IMO. If you want 'one head to do almost everything' pretty well with a wide variety of cabs and contexts, I would consider the Shuttle Max 9.2
