Double Bass Evah Pirazzi Solo Tension

But Dominants are somewhat stiff by design.
Tension is not the sole variable here.

The tension of Dominants are lower on Dominants (27,00 kp) than Obligatos (29,70)...Actually dominants are seems the lowest tension solo strings on market, but you say practically the Dominants feel stiff in real life? I like Obligatos Orch strings so much, but Afraid to go to Obli solo, because 29,00 kp seems too much for my 108 cm scale bass....

Dominants are designed for 104cm scale and the tension numbers are for that scale.
At 108cm you'll have more tension.
The scale for numbers for the Obligatos is not given in the spec, but I think it's probably 110cm.
Maybe @DoubleMIDI will chime in with more accurate numbers!

Thanks for the attention…I thought, all tension infos from the same scale….
I think I”ll go for Obligato, Flexocor is lower tension, but I tired in the scool on a Mayer bass, it sound’s too “metalic” for me, I like Obligatos orchestral, the solo versio is higher tension as the orchestral, but I hope will works….

Look into the excel file in my Dropbox.
The 2nd last column shows the tension for the given scale length at the top (the last is for detuned strings, see below).
If you only compare string data from that file, the scale length is not important.

It might not be easy to find lower tension solo strings at solo pitch as the solo bass should (in general) sound brilliant and loud to cut through and that won’t work with lower tension strings.

Find a orchestral set that is lower tension in medium weight and where a solo set exists, as solo strings typically have a comparable tension to orchestral mediums at solo pitch, but often with a bit less tension on the lower strings.

A longer scale makes things more complicated, I have a similar problem with high C strings on a 110 cm scale.

As a last possibility you might find a high tension orchestral set with a high C string (i.e. Evah Pirazzi or Spiro Mittel 3/4) and tune it down by a minor third. But that might be too less tension.

In the newest version of my excel file the last column contains the tension for a detuned string, usually set at -2 for the tension of downtuned solo strings.
But you can set it to -3 and read the tension for high C to A orchestral strings that will then sound at solo pitch.

Thank you, for the informations.

I totally satisfied with my EP Which G D and Obligato A E orchestral set on my bass, but now I have to set up my bass for solo for my Master Degree project...
I just afraid to be to stiff feel on the 108 scale bass, and I use exclusively synthetic string in the last 10+ years, so I not really like all metal strings anymore...
I don't want to be an expert of the solo strings and tension, just like to get appox. similar feel of my current setup, and start to practice....:)

There was a Solo set of the Innovation Braided (at least when they were made in the UK), but the high A was aluminium wound. Never had it as I don‘t play solo tuning, but the Braided Orchestrals bow(ed) well and tension was in the EP Weich Range.
Never had a GHS set yet.

BTW, tuning down a piccolo bass set (high C to A) by 3 halftones gives you 71% of the tension for the intended pitch.
That means if the high C has 30 kp at pitch, it gives you 21 kp downtuned to A.

108 vs. 105 cm gives you a tension rise of 6%. The tension rise of 6% gives you 22 kp from the example above.

Use Formulas.html from the Dropbox in your web browser, find the right formula and enter data in each field but the last for the formula you need. Don‘t forget to press enter after the last data entry.

Allright, put an Obligato set to my bass. I’m not sure they will works well on that bass….
I have a new question, what is the lowest tension, but not gut solo string set on this planet? If it sounds brighter or darker, I will try to deal with, but seems I need something very low tension, minimum stiffness for this bass….

If your bass is so problematic with stringing then it may need either:
- a good setup
- be sold and get a new one
Good luck anyway! :)

My bass, has very big, nice sound! The tension is good for me, with orchestral EP Weich and Obligato, but too stiff with Obligato Solo set with solo tuning, so I need lower tension Solo strings for my solo project, and after I go back to orchestral setup, that's all....
