I just put a set of the flex-steels (45-105) on a Suhr J bass I recently acquired. …
These obviously aren't for everyone, and probably not for every bass. I have a 5-string set I'm going to try on my PJ-5, but I'll wait until the Sunbeams I've got on there now are done. …
I probably won't use them on all my basses, but definitely will on at least one so far.
As I suspected, these aren't for every bass. The Flex Steels had worked out so well on my Suhr Jazz, that I finally tried a set on my Celinder PJ-5, currently strung with Sunbeams. This didn't work out as well, i.e. at all! Absolutely the wrong set of strings for that bass. Within 5 minutes I switched back to Sunbeams.
In hindsight, I think these *could* have worked out better under different circumstances. First, the set I have on my Suhr are the hybrid EFX165, 45-65-85-105, rather than D'Addario's default gauges of 45-65-80-100. The 5-string set is 45-65-80-100-130, and to me, playing a bass with that big a difference in gauge between the E & B strings is like walking in a pair of shoes that have one heel missing.
Guage issues aside, the E-A-D-G strings felt and sounded pretty good, but the B-string sounded unfocused and hollow. This bass normally has a B that sounds truly amazing, but the Flex Steel 130 sounded like someone threw a blanket over it.
I think that perhaps a 5-string set gauged 45-65-85-105-125 might have worked out better. I don't understand or agree with D'Addario's tendency to populate their string sets with lighter E & A strings, and not everyone wants a 130 B. In the case of this bass, I don't think combining a hybrid 4-string set with a single 125 B (if they ever produce that single) will work either, since I need a super long set for this bass. (As it was, the D string was almost too short for the Celinder's 4+1 headstock configuration.)
I still like the Flex Steels on my Suhr, and I want to try a set of the lighter EFX220's on another jazz bass to see how they'll do, but I think the Sunbeams are the right string for my PJ-5, and that made the experiment worthwhile.
