Yeah, not sure where these claims of no low end from the 7 Pro are coming from. I crank my bass knob (to around 3:00) and that thing thunders. Then I add just enough mids and highs to sit well in the mix. The amp practically demands sonic space in the band mix.
i can't imagine needing more low end than the 7pro has to offer, especially if you crank the bass control.
IMO, the 7pro has just as much low end as an SL900, it's just not as scooped in the mids.
I definitely hear what I'm describing, I just don't know how to describe it... The 7 Pro sounds HUGE and WIDE, but not SOLID. The Streamliner sounds deep, but focused and not huge, very very controlled sounding even with lots of bass boost. With the streamliner, I can cut all highs and mids on the bass, and I can still clearly hear the pitches of the lowest notes on my B string. With the 7 Pro, those low notes become hard to distinguish, and I feel like I'm hearing more harmonics than the fundamental. If I boost the bass on the 7 Pro, it gets very heavy and bassy sounding, but it's as if I'm hearing very heavy bassy harmonics.
what basses are you playing? Strings? Effects?
My Fender Jazz straight into the 7, into my bergantino hd410 is ridiculous. I was having a hard time dialing in super lows with my P, but the jazz with the active pre-amp blows doors...
My main bass is a Nordstrand NJ5 (34.5", Alder body, Cocobolo fingerboard) with Big Singles and the Nordstrand 3-band preamp, Circle K strings with a .136" B. It is a very fat and round sounding bass, with a touch of modern to the tone. For testing purposes I'm going straight into the amp, but I often play with a B3K on the "fat" setting, with the drive turned all the way down. The speaker is a 15/6/1, so the low frequencies are very present and obvious.
The SVT-7PRO manual says that the Bass control is +/- 12 dB centered at 40 Hz, which is fairly low/deep. Perhaps a bit more EQ sculpting is in order.... maybe try dialing back the mids/treble to find the appropriate balance with stronger lows (subtractive EQ often works better than boosting). Very few amps share the inherent massive bass which is present in the Streamliner, so it is easy to understand why most sound relatively thin in comparison.
I hear the low bass in the 7 Pro, but it has a "boomy" quality to it when boosted, rather than the "solid" quality I hear in the Streamliner. Again, what I'm hearing is as much of a difference in the quality of the bass as it is quantity. Also, don't want the 7 Pro to sound like a Streamliner, that would defeat its purpose. At a rehearsal I noticed that the supplied 1001RB sounded much heavier and lower than the 7 Pro, even if I cranked the bass on the 7 Pro.
I agree.. The taper on my SL900 seems very smooth to my ears... No real jumping out at you all of a sudden in the middle of the rotation or at the extremes. I like that...
One very interesting thing I learned in testing: the SL900 master gets most of its volume between 7:00 and noon, and you get very little change after that. The 7 Pro is quite linear all the way up, so noon is not terribly loud, but you can get almost twice as loud if you keep going.
The other thing I keep noticing is that the Streamliner preamp has lots of headroom. Almost anywhere I set the levels, I can hit very softly or very hard and get smooth changes in tone. On the 7 Pro, it's more of a balancing act between getting enough gain and having the note attack fuzz out. I don't know if that's a bad thing, is that how a tube SVT works?
