I just installed a K&K Pure Bass pickup for 5-String Acoustic Bass in my upright guitarrón and ran it through a K&K Pure XLR pre-amp and into an Acoustic AB50 practice combo. This is the first time I've dealt with amplifying anything, and I have a question: After trying several positions, it seems to me that all six strings are sounding best--i.e., most natural and most even--when I cut both the bass and the treble a bit and boost the mid a bit on both the pre-amp and the amp. In fact, the clock-face positions of the three knobs are identical: 1030(bass) / 1330(mid) / 1030(treble) on both the pre-amp and the amp. Both volume settings are quite low for just my own practice at home. I'm getting what I consider to be a nice, tight, well-defined bass with no muddiness, boom or honk. So, my question is: Do these pre-amp and amp settings make sense with each other? I'm guessing that you're all going to say that I should just go by the sound and if you do, that'll be fine. I just want to make sure that I'm not bucking some established and accepted convention here--somehow making the pre-amp and amp work against each other, say.
