Does anyone use flatwound strings on their Alembic bass?  If so, what are the best brands
to use? Any and all advice is welcome.

D'Addario Chromes!  

Thomastik-Infeld jazz flats.  Carol Kaye calls 'em the Rolls Royce of strings & I totally agree; I use them on all my Alembics.
 
Valentino

for 4-string - the Chromes with the Jazz Flats a really close second (can't go wrong with either).
 
for 5-string - Jazz flats.  The B-string on the Chromes is worthless.
 
C-Ya.........wayne

I also use Labella Deep Talkin' Bass nylon tapewounds on my custom 6.  Those strings really sing - very mellow and sweet.

I had the d' Addario chromes on my former Jazz-bass and using them only in big-band conditions. I liked them. OTOH there is not much to get over here, so I can't really say I CHOOSE them.
 
Paul the bad one.
 
Hi Brother Rami: you mean the fretless twin??? I think those Labella's are also used on the Rob Allen guitars. See www.roballenguitars.com
I LIKE THEM (yes Paul TGO ...again ...they too!!!!)

TI Jazz Flats all the way.
 
And stay away from K*n Sm*th Slickwounds: utterly unplayable.

Hey Adriaan,
 
I guess you buy your TI's in Holland? Or at a net-store? Can you help me. I really want to try those TI's and I don't get a hell of a choice in this apenland.
Please e-mail me. I would e-mail you but I'm not in place where I can use normal e-mail connection to SEND. I can receive however. You'll find my e-mail on my profile.
Thanks for info!
 
Paul the bad one
 
PS: You cab even call I guess because I see my mobile is there too!

I like the D'Addario Chromes, but once in a while I get a set with strange overtones that makes the instrument sound out of tune.  
 
I do like the TI's too, they are just different.  I find them more midrangey and work better with my series II.  I also like the low tension of this string.

Hey Paul,
 
You've got mail!

huh-huh
and in the end we meet in a park between the flowers and your bass called Kimberley is pulling your sleeves when we ...
 
na-aaaaaaaaaaah

Let's meet at the top of the Empire State Building. And don't forget to bring the Kinder surprise - it's a miniature bass rig! Goes wonderfully well with the purple cows fom Switzerland, only the brown notes keep woofing up after an hour or so.
