Has anybody any experience with mixing the NS strings with full length double bass strings?
My hands are itching to experiment with new strings (I was a string addict on my dB. I'm afraid I'm starting to show symptoms for EUB), but because the holidays are coming I don't have a lot of cash to pay around with full sets. I do however have some strings laying around in the drawer that could be interesting.
If you're going for a more "real" sound, trying some of the strings in your spares drawer is certainly worth a try. But strings react differently on the NXT than they do on a "real" upright bass, hence the reply from @crocau, above. And I agree that the varied timbre of different strings will be much more apparent on the NXT, so "mixing" them might not be a good long-term solution.
Here's my philosophy on the subject of strings: The best any EUB could hope to achieve would be to sound like a double bass with a pickup on it. Since the NS Design basses are tightly constructed and are solid-body instruments, their habits lean towards a more electric sounding bass... more sustain, more string detail, that sort of thing.
The OEM/stock strings (NS Electric "
Contemporary" - which are
NOT Helicore strings, they are manufactured more like ultra-long scale bass guitar flatwounds) don't help; they're fairly un-upright-like in my opinion. In my experience, using strings which pull it towards a more URB-oriented sound (quick decay, short sustain, a more blunt attack to notes, almost a gut-string-like vibe) will effectively counter-balance the electric nature of the bass.
Two strings which I have personally tried and found success with are the
Pirastro Obligatos and the
D'Addario NS Electric "Traditional" Strings. Both have a darker, less defined tone which sounds great on my personal NS Design Bass, and both strings fit its bass-guitar-sized tuning machines. I have the Traditional strings on my personal bass and like them quite a bit; I've also strung up several customer's basses with the Obligatos.
For what it's worth, the NS Electric
Traditional strings
are made by shortening the afterlength of D'Addario Helicore Orchestra strings. Those are the ones that @crocau may have been speaking of. If you have a set of Helicore Orchestras (or even Hybrids) lying around, they are a great choice; to string them up, you simply wrap the strings around the bottom of the bass and up the back to the "keyholes" for the ball ends. This is also how you can string up most any other 3/4 size upright bass string set.
That's my personal take - obviously, strings and tone are very subjective, but I hope my comments provide a little insight to help you along.
Finally,
Invalid Link Removed; he posted it on another thread, and it features him bowing the bass equipped with D'Addario Helicore Orchestra strings (I believe he's also using a reverb pedal set subtly to imitate the resonant body of the bass).
