Here are some audio clips. If you've ever heard some of the sound samples I've made in the past, I'm a fan of tones that have a bit of edge and grit/dirt, and are not necessarily pristine. This set of clips is no different. TOOL, RHCP, AIC, STP, and others of that ilk are among my favorite bands and bassists, so if you're looking for polite tones, you'll not like these at all, and apologies that maybe this demo series is of little value to you.
First, I've posted a clip of my Schecter Stiletto Studio 4 string bass, essentially dry with some B3n LMT-76, as a reference (tones set flat, both pickups). It's (for me) a perfectly workable tone as-is, and I've gone fully direct with this bass with nothing else and happily gigged. What I like is how much of an effect the amp/cab modeling have on the tone, and to me it is as good as a mic'd version of the real thing. Of course, you may disagree.
Next you'll hear versions of both the B3 and B3n going into the SVT model/cab sim and then the Limiter. I did spend some time to consciously make these sounds to be pretty close, and they both have a fair amount of amp gain for some hair/overdrive. You may not think that there's much of a difference in the tone, and I'd have to agree, in this context. The settings between both devices are totally different, though, and the B3n amp model has a more flexible and realistic range of sounds/settings IMO. Obviously the cab sim has a lot more flexibility now, and is a different animal than the SVT 8x10 sim in the B3.
Next, you'll hear the same signal chain SVT--8x10--LMT-76, but with the SVT's gain lowered and cleaned up. This is because I wanted the Darkglass PRE and OD to provide the distortion you're hearing, with is quite a different flavor than what you get from the SVT preamp. You may also notice that the Darkglass PRE and OD sound pretty similar the way I've set them, although the 2 slot PRE is ultimately far more flexible, while the OD gets you the flavor but not much control for the tone/EQ.
Feel free to skewer me or fire away with pointed questions. Also, I'm soon hoping to get going on some special effects comparisons and demos for the B3n.
Jimfist, you have a fractal, there are many differences of sound quality between the zoom b3n and fractal axe?
