Do you find this true on both the ash/maple as well as the alder/rw one? I ask because at least on my alder/rw one, it might lack a bit of overall gain compared to a lot of my other basses, but if I crank the amp a tad, it sounds fine. The reason I haven't looked at raising the gain of the preamp is because I like the fact that active (at least non-boosted) mode is closer to passive mode in overall output.
Interestingly tho, I do agree that, unlike a lot of my other stuff, I really like the tone of this bass with an overall eq boost, where on a lot of my other stuff, that would tend to be a bit much. I think the main diff here, is I actually do like the sound of mine "flat".
Then again, maybe I just suck that much as a bass player... could be...
