Hello,
I've been looking for a micro-ish rigs lately and am wrestling with a Genz Benz Shuttle 6.0 12T combo that I've been testing for my "basses for newbies" project detailed here:
http://www.talkbass.com/forum/showthread.php?t=627147
The criteria I'm hoping fulfill are:
compact (1 trip)
expandable (can use extension cab for bigger gigs)
full and loud enough for general, reasonable volume gigging
clean enough for use in studio
generally fun and inspiring
not over-the-top price-wise
The form factor of the GB units were favorable. I have in hand a Shuttle 6.0 12T combo and have a Shuttle 9.0 head incoming for testing.
I'm having a few issues with the Shuttle 6.0 head as well as the 12T cabinet and was hoping some more knowledgeable folks here on forum could chime in.
First off. . . lack of low-end extension on the 12T cab. To my ear, the cab is dying off on the fundamentals in lower notes, and I start to hear just overtones. This becomes particularly appearant when using a 6 string bass. Is the NeoX 12T a lot better in this regard? Same drivers. Looking at the specs provided regarding frequency response, there is no difference. The cab is breaking in, so I've been going real easy on it volume wise and not slapping on it yet, and it does seem to be opening up a bit with each session.
Another issue I'm hearing is what seems to me to be a harshness and frequency spike in the upper midrange.
And, another strong concern of mine is a lack of transparency or 3 dimensionality in the tone. I feel like the sound is "flattened" or veiled. It is certainly loud enough and in broad strokes, the general vibe is present, but I can't get in there and hear a lot of the analytical nuance and depth I'm needing to hear.
For general information, the rigs I am somewhat familiar playing/hearing are Thunderfunk 550B--> Acme B2. . . (my rig) and my other bass tester's main rig Walter Woods --> Accugroove Tri 112.
After identifying what I felt were the problems (listed above), I tried to isolate the sources. The main components in my mind are preamp section, power amp section, and speaker.
Taking the 12T cab out of the loop and plugging the Shuttle 6.0 head into the 4 ohm Acme B2, I found my bass extension again. The shuttle also seems quite capable of driving the B2 to max volume without huffing and puffing too much. Still it feels a bit rolled off in the bass and the upper midrange spike though reduced is still present. I figured the 12 inch speaker that I'm not intimately familiar with has a spike there as well as the amp. Still, the sound was a bit veiled through the ACME cab and I was not able to get the detail and 3 dimensionality I get with WW or Thunderfunk driving this cab. I'm not sure the 12T has enough punch for what I subjectively consider adequate for general gigging on its own.
In an attempt to isolate the preamp, I unplugged the speakers from the head and set the XLR output to post. . . and then connected it to a Yorkville A4.4 power amp driving first the 12T cab and then the ACME B2 cab. With 1200 watts per side of clean power, I figured I could take a listen to what the preamp was doing with the shuttle's power section out of the loop. In this configuration, I was able to regain a lot of transparency and depth. Switching back and forth between the external power amp and the Shuttle power section, I found that at least a significant part of the "flatness" is coming from the power amp section of the head. The shuttle is plenty loud. . . just not as transparent and 3 dimensional.
The preamp still retained what I felt is rolled off bass and upper midrange spike although everything was a bit sweeter running through the power amp. I suspect a compounded mid spike in the 12" driver with the power section's characteristics made the 12T combo sound a little hashy in the midrange to my ear.
In reading posts on forum, I've ordered a JJ ECC83 tube as a handful of people indicate that this flattens out the tone curve a bit (smoother mids and more bass extension), and it a reasonably priced piece. I also read that significant changes were made to the power section of the Shuttle 9.0, so I'm eager to hear that unit when it comes in to see if power section issues that I'm hearing on the 6.0 are largely improved.
I'd love to know if there is something I'm doing wrong or if my expectations from the 12T combo are just not reasonable. Also, is there another setup within the Genz Benz line that would work a lot better? Or am I hearing the general vibe and voicing of the GB line of compact cabs with this 12T?
I'm also interested in going back to the drawing board and searching for other combinations that have worked well for people here given the criteria I mentioned at the beginning of the post.
