I disagree, the bass level sounds fine to me; and your tone is nice and even across the frequency range. Very nice recording on the H2.
I like the version of Costello's Pump It Up. The bass lines move well, which is of course a highlight of that song. Back in the seventies, there was a period where I heard a lot of Costello's stuff, and I got to see them live once. The thing that did it for me was the bass lines; I think Bruce Thomas' lines were wonderful and really helped to make the songs the innovative tunes that they were. He was the perfect bass player for those songs. So I enjoyed hearing you cover that tune!
