For what it's worth, the Fender JMJ Mustang is factory-equipped with the long scale 9050L flats. They don't seem to cause any issues. EB Group Flats are very similar in construction, so you can always try the long scale and see...Just realized that EB don't do medium scale strings, and their shorts are too short for the string-through Mustang. And the long ones are too long.
Or am I missing something? I'd want the Group 2.5 flats.![]()
I have LaBella DTF's on my Musicmaster, so I want something a bit less dark for the Mustang (that I haven't received yet though). And I have EB Cobalt flats on an Acinonyx and I suppose the Group flats would be somewhere in between those extremes.Any reason you are stuck on Ernie Ball 2.5 flats? Labella makes excellent Mustang fit strings. I run their flats. If I wanted something brighter, but still not round I would do the Labella Super Polished Mustang Bass set.
The JMJ has larger tuning posts than the Vintera II that I'm getting though. So that would both require more turns (if I can't cut the strings before the silk, which I think I can't) and also bend them to a smaller radius. Not sure how good idea that is.For what it's worth, the Fender JMJ Mustang is factory-equipped with the long scale 9050L flats. They don't seem to cause any issues.

I see what you're saying. I wasn't aware of the difference in the size of the tuner posts. Maybe the long scale flats are too risky on smaller posts.The JMJ has larger tuning posts than the Vintera II that I'm getting though...
It will probably work, but flats are expensive. And you never know what happens when/if you have to take them off the tuners to do some maintenance or similar. E is also most prone to sound crap even when everything is optimal.I see what you're saying. I wasn't aware of the difference in the size of the tuner posts.

Didn't know about those! Will investigate... But I doubt they are available over here.If I were after an in between on those two, I would go with the super polished. 760SP-MUS La Bella STANG - Super Polished
I have not tried the Mustang scale version, but I have MTD Super Polished (by Labella) on another bass. Brighter than DTF, but not roundwound bright (which the Cobalt flats are near).
Didn't know about those! Will investigate... But I doubt they are available over here.
However, to me, flats are not about brightness or lack thereof, but about the attack and smooth feel when playing. I've tried a few different halfrounds, groundwounds and so on, and none of them feel like flats. So not sure if these Stang ones are any different...
Edit: The Cobalts are the only ones really breaking the rules IMO. They feel (and are) like flats, but sounds like something else. Not really rounds either. I could probably be happy with them on the Mustang too, but, wrong length.
The long scale Cobalts definitely work on a Mustang... I read about it on here and tried it myself. No problems, except that they pinch my arm hair like crazy, and so I hate them for that.Didn't know about those! Will investigate... But I doubt they are available over here.

Yeah, I just mean that all flats still have something in common that rounds/grounds/halfrounds don't. Even the Cobalts sound like flats if you don't dig in too much.I would argue flats have a pretty wide range of feel too. As an example, I absolutely hate D'Addario Chromes (stiff/tacky/sound too bright). My favorites are TI Jazz Flats (which do come in a 32" scale version that should work on a string through Mustang Bass). I run Labella DTF on a Vintera Mustang Bass and a Player II Precision bass. Cobalt Flats are on a G&L Tribute Fallout bass. All three sets feel a little different, but play/sound great.
I have tried some other groundwound/halfround strings and never been a fan. I find that I like that Labella Super Polished. That does not guarantee that you will like them. Just mentioning that to me the Super Polished is different in a good way.
Maybe. I’ve gotten long scale flats on short scale basses but I broke E and A strings figuring it out. Gentle massaging to pre bend the string onto the post as you’re putting tension on is the key. But I only got it to work reliably with more flexible strings like TI flats. And only on big posts like a Fender. Stiffer strings or smaller posts can work but it’s a crapshoot. 100’s are more reliable than 105’s and 110’s just break.It will probably work, but flats are expensive.

How about the Dunlop Flats? They're one of the more flexible flats but not too floppy. And they do come in medium scale with 34" winding length. They're also fairly close to the EB Group flats in terms of their tonal character with a nice midrange clarity.Edit: I think the Cobalt flats 50-70-85-105 on my Acinonyx (30.7" scale) has close to perfect tension. A smidge higher would be even better.
Yeah, I had some leftover Fender flats I tried on a Player Mustang neck. A-D-G were fine, but the E string wrap didnt go well.The JMJ has larger tuning posts than the Vintera II that I'm getting though.

There are strings I would like to try, where the price is just too high to take the risk. Dunlops fall into that category, unfortunately.How about the Dunlop Flats?

The only thing about the Dunlop, though, is they're twice the price or the EB Group Flats.
Maaaaybe...
