I'm sticking a copy of a post I had in another sub-forum here. I'm looking for a 'darker', flatwound string. Here's the post:
I love the way my Smith Burner feels and plays, but I hate the sound of it- it's very narrow, upper-middy-honky sounding. Downright brash for my ear. I want to try putting some deep-sounding flats on it and see if I can get it to be a little more thumpy. I like some growl, but it has to be down low, not up in the Jaco-spere. Those nasally-upper mids are screrwing up my experience.
If new strings don't do it I'm going to put Fender Jazz (stock) p'ups in it. The stock "Smith" p'ups are suspect as a prime cause of my discontent, I believe, anyway...
If that doesn't fix it for me I'm going to try a Bartolini preamp a fellow Smith-player is sending me. The existing Smith 2-band pre does not work properly, and I can't afford a new or re-built for a while.
Whatever works I'm going to post as a mod. The (sort of) sad truth is
I want it to sound like a Fender! The string-spacing is very good for me, and the feel of it is awesome. I also like the look of it- it's different, and has a sort of 'snooty' vibe; very 80's English-pop looking! If I can get it all to work out I'll do my (in)famous strap-jig to it, and it'll be all set.
Here's the Smith:
Here's the (in)famous strap-jig, not on the Smith:
So, any recommendations for nice medium-low tension flats that'll keep me in the low-downs sound-wise, and less in the upper-mids? I'll appreciate any constructive remarks, and fend off the hammering I may get for modding a Smith bass!

Thanks!
