Double Bass 5-string tension problem

[jcobalis]

I have a 5-string Gyorgy bass. Recently I tried the bass after taking off the low B, and the bass plays much more freely with just 4 strings. My guess is that the less tension from the 5th string has allowed my bass to open up.

I could have 4 new slots carved in the bridge and be able to convert between 4 and 5 strings, but It would be a shame to sacrifice sound quality and playability for the low notes, and vise versa.

Just wondering if anyone had any ideas as to how I can keep the bass as a 5-string, but also keep the sound and ease of playability from when I only had 4 strings. (ie. ideas on how to release tension on the bass, etc.)

Thanks for any ideas!

I am convinced that one of the most devilsome problems in DB construction is getting a bass built that has enough tension to get the instrument moving without also choking it. It is a delicate balance akin to adjusting the spring in a mechanical watch (And some are of course asking what is a mechanical watch.) You have to wind them up.

In this case, you have taken off a string, which changes more than the tension. The fifth string, (because five really fill up the bridge) also "stays" the bridge more than 4 do. It is the position at the edge of the bridge as well as the added tension. If you have the option to go to lower tension strings, you might try that. I had my 5er loaded with light tension strings right from the factory in anticipation of the choker effect. I think it helps.

So let's review: You want to lower the tension of 5 strings to equal what you have with 4. You need strings that tune up with about 20% less tension across the board. Most manufacturers publish the working in-tune tensions of their strings for a given stop. You will have to research a little to find the right strings to try this out, but it should be a step in the right direction.

As a five string player, I would advise playing around with the sound post...don't forget, the right sound post placement not only has an effect on the sound of your bass, but also the feel. Any thing that applies to getting a good sound/feel out of your bass as a four stringer, applies to our fivers.
If you don't have the tools or ability to do this yourself, get the bass to a good luthier. You really should adust your sound post in concert with your different string changes.

Another approach that you might want to try is raising the saddle to decrease the break angle over the bridge to decrease tension. You really need to get to a luthier, as none of the suggestions are do-it-yourself projects.

I have a lower-end 5 string, by Christopher. Originally it had helicores. When I switched to gut (for the D, G, and C strings) the instrument opened up incredibly. Now I am in love with her. I would definitely try the lower tension route - string change first.
