I don't think I've ever heard Chromes described as anything approaching dark before! (I found them scooped every time I tried them years ago.) But I'm glad you may be on to something. It's further encouragement for me to reconsider Chromes at some point. I'm just going to need more basses......
You might be right about the Chromes. What I posted was just my initial impressions and doesn't really reflect much more than about 15 minutes of play time after the setup. I'll check the setup on the BaCH once more today and make any final adjustments before running it through its paces in numerous genres of music.
I usually run a battery of several songs in four sets of music...
1) classic rock, country, funk, club dub, reggae (Black Beauties did good on this bass - strong, deep)
2) jazz, swing, big band, waltz, orchestra (Black Beauties were lacking here - slow, muted)
3) piano tracking (Black Beauties were ok here)
4) solo. (Black Beauties were ok here - dark but clear, minimal finger noise, muted top end)
That's usually enough to highlight any short comings or strengths the strings have on a given bass. It's important to note that strings may be fine on one bass but lackluster on a different bass.
