...How would you describe this "new tone" your TI's have developed?
Ah, the art and science describing tones. Let me see....
I have these on an Fbass AC6, which ships with LaBella rounds that sound WONDERFUL, except --
Whenever I grab a fretless bass, I have 1 of 3 tone targets in mind: Jaco Pastorious, an acoustic upright, or Alain Caron.
For Jaco, I use the magnetic pickup near the bridge, obviously. For an upright-y tone, I use piezos (the bass has chambers to help as well), and Alain is a blend of the two.
The LaBella rounds were perfect Jaco and Alain, but an uprighty tone was possible, but not convincing.
When I put the TI flats on, the uprighty tone was convincing even to piano and sax players who play nothing else but swing jazz with upright bass in the rythm section. It is wonderful.
However, while the Jaco and Alain was okay, I was dissatisfied. In fact, I started telling my wife I need another fretless 6 string for round wound playing.
Just as I was looking around the used market, something amazing happened to the TIs, and I could hear the transformation very clearly.
Instead of a drier, somewhat thinner and brittle tone of highs and high mids, the emphasis dropped to the mids.
But this wasn't like round wounds losing their brightness, it was more like when you start playing basketball and you are still sore and stiff from the day before, then after several times up and down the court, suddenly you feel agile and quick and competent and the brittle "gee I'm getting old" feeling is gone.
I don't know if that helped AT ALL...
But what it did was reinterest me in playing the Jaco and Alain tones.
The mids and lower mids punched through and the mwah was much stronger and controlable with my hands.
I recorded some lines with the rounds before I removed them, and with the TI flats when they were fresh on the bass. I played that recording back, and then played the lines now, and there was a distinct warming of the bass.
It was like whole milk had been added to the cocoa powder I'd been licking, and everything became much creamier.
I don't know; I shouldn't be doing this.
Like I said, I haven't used flats in years, so I'm used to strings being too shrill, then losing their overbrightness, then getting useless. I was not expecting these strings to go from very nice but thin, to WHOA! Slide on over baby!
