Hi there friends,
I'm in a terrible work-fase so I have not the time to jump into discussion regulary. Now I can just write this about the strings I use.
Originally I used superwounds (now by Rotosound I guess) on my S II five string. They were naked core (I guess you call it) and they were great. Helas, hard to find over here in Belgium. After that I used D'addadario Round wound. I don't remember the numbers but they were called soft so I guess they were not too heavy as gauge. I used them for a couple of years.
A week ago I switched to DR (hex core - thight wound) and I went for this odd gauge: 120-100-80-60-40. Well it looks like an even serie but ...they sound exactly like that. I find Alembics to have a tremendous response so in my feel the low tones are frequently out of control. That's why I went for less powerfull strings. They have a light feel and they sound very even on every position and giving good result on slight finger trills knowing that I play a fretted bass.
Now for the flatwounds.
In the big-band I play a Fendder Jazz-bass. With the rythm section I agreed to look for an old sound. So I decided to leave the Elixirs roundwounds on it and go for flatwounds. The shop here in the neighbourhoud was friendly enough to order for me ...D'Addario chromes flatwounds but here I again went for the lightest gauge offered. Low E is .95 I think. Now unfortunately they didn't arrive yet. I promise you to keep you posted when I get them on and did some work with them. It's possible they turn out wrong (because the jazz-bass has definitely NOT the response like the Alembic) but hey ... that's what it's all about in looking for sound: I'll change again... to the heavier gauge of D'Addario or another brand. Admit: you'll easier buy another set strings then another Alembic.
About Tune.
(It's a feeling of mine and I want to start another discussion on shaping bass-sounds but I'll keep that for the future when I'll have some more time to react.
I think that the tuning-problem you have is in fact ... in your ears. The bass sound from a flatwound is different from a roundwound. I say: a flatwound on an electric bass gives the bass-sound poor edge. So the note you play spill of its sound to the next you play and starts mixing up weird with higher sounding instruments. I studied upright-bass for 4 years and in that time I had the time to compare with the electric I had and how Sound was formed. The accoustic characteristics of the up-right bass (wood-clicks, touch, woodcontacts,the playing physics) are adding the correct edge to the sound of the flat strings. An edge hard to obtain in the electric way. I even had some experience with tuning the electric bass with flatwounds a slightly bit higher. There was this old bass-player who told me :the bass sound has the character to 'lower' a bit making the voyage to the audience. And it's for some reason more audible with flatwounds. On my old Korg tuner I tune my strings a slightly bit above the green middle position.
Maybe all rubbish ...a mere feel of me.
Anyway ... I was glad to be again with you all and will keep in touch when I'll have the time.
Be Alembicious!
