Unwinding Strings
I like to build short-scale basses, Unfortunately, the manufacturers don't like to make short-scale strings, and stores don't like to stock them. And some lengths, like 25" 'pico', simply don't exist. However, you can make your own from readily-available long-scale sets.
Unwinding a string to any length is easy. Put it on the guitar and figure out what length you need, or where you need to unwind to. Saturate the inch below that point with Crazy Glue to fix it in place, just a couple of drops will do. Cut off the excess string, then unwind the outer windings, but not the inner windings, enough to give you a tail to wrap on the tuner post.
Try not to twist the entire string, that could ruin it, grip it tightly at the Crazy Glue as you unwind. It will take a while, and you will end up with a surprising pile of spiral spaghetti wire when you are done. Finally, smooth-in the cut winding and Crazy Glue it down so you don't leave a sharp point sticking out. I have found that unwinding is necessary on strings larger than 085". That size and smaller will wrap on a bass tuner post without modification.
Most long-scale string sets will work fine down to 30". Shorter than that, and things get sloppy, heavier strings are necessary. You can experiment yourself by capo-ing a standard scale bass at various frets and then re-tuning it to EADG. On a 34" bass, the first fret makes 32", second makes 30", etc, 5th makes 25". See for yourself if you like how it plays.
To make a 25" pico-scale string set, start with a light 5-string set. Remember, an EADG pico is the same as a BEADG 5-string, capo'ed at the 5th fret, minus the G string. An off-the-shelf D'Addario light 5-string set is something like 125 100 080 060 045. I don't recommend a heavier set, as when you shorten a heavy B/E string it gets a very stiff feel, a 125 feels much better. Anything in the ballpark will work; if I was to spec a custom set, I would try 120 100 080 060, or 115 095 075 055, but going with a standard set will save you money, and it doesn't make that much difference.
Once you can do this, you can make any length of string you want out of anything that is available. 25" half-rounds? 30" flats? 27"? No problem. In my case, I have a box full of long-scale strings just waiting to be re-purposed as shorts. Individual 125 strings are also commonly available at reasonable prices. So start exploring the world of custom-scale basses - it's fun !!!

This is the scrap part of a 0.125 low-B from a 5 string set. You can see a core of steel wire, with three layers of wrapping. The innermost looks like copper, surprised me, I've not seen that before. Then is a silvery layer of ( I suppose ) nickel, and then the outermost wrapping. The 105 string had the same copper layer and outer layer, omitting the middle layer. Since I didn't want the copper to show, I just crammed the 105 into the tuner rather than unwrapping it, but there is no way you could do that with the 125. I guess it is a good idea to do a test unwrapping on a piece of scrap before you do the real string.
And these are the strings, which came straight to my door from the other side of the world for only $9.99, thanks to the miracle of the eBays. "Pureee Nickel" "Ligh Gauge" - me thinkee someone at Fender's China division no speakee goo Ingrish. The back has several other languages, looks like French, Spanish, and German. The fold actually says "Fender Musical Instruments, Chula Vista CA 91911" and "Assembled in Mexico of US Materials." And then sent to Fender's warehouse in China, so they could be distributed to the world! I thought Fender moved to Arizona years ago. Nonetheless, these are clearly authentic Fender strings, no doubt about it, no siree !!! If you believe that, you wanna buy a bridge ?
Anyway, curiosity got the better of me, so what do they sound like? Well, actually, they're not the worst strings I've ever had, but that's about the nicest thing I can say. The don't have the
zing of a brand-new set of roundwounds, not at all. Personally I don't care for that anyway, I prefer the sound of a broken-in set. They're strong and even, but dull, almost like flats. Even unplugged, they are much deader than the strings on the other pico, more-so than I think could be explained by different bodies.
I recently also tried a set of inexpensive Darcos, which I found to be quite acceptable for just a few bucks more, and would even recommend for the budget-conscious. Multi-packs of D'Addarios can also get down almost into this price range. These strings are not really a bargain, and I would probably not get another set. I have a box full of old bass strings that I can re-purpose to get the same effect for free. But like I said, they're are not completely terrible, and I will probably leave them on. I was half expecting to be immediately stripping them off and into the trash can, which may yet happen.
The worst bass strings I ever saw were the factory set on my Rondo SX Precision. Considering the whole thing cost $109, you really can't expect a $30 set of strings, but those were so bad that they were practically strangling the instrument. They barely registered in the pickup. As soon as I replaced them with a good set, it woke up and sounded fine. Ultimately, I also replaced the pickup with a USA Fender, and did a super-fine fret dressing and setup, at which point it sounded and played as well as any real Precision. Those strings did go straight in the trash can.
The other thing that can go wrong with a wrapped string is that the wrappings are not tight to the core. Such a string will buzz and rattle. I got a string like that on the incredibly cheap Brownsville violin bass I picked up on a whim one day at Sam Ash. With a good set of strings and a setup, it is a fine instrument, as good as an
Icon for a fraction of the price. Then I dolled it up with pickguard and other trappings to look like Sir Paul's. Sort of. If you squint. With a nice set of flats on it, it does have that famous woody thump. I once saw a kid playing slap-and-pluck style on a violin. It was awful.
Both these cases illustrate the fact that many inexpensive instruments can be made great with some simple upgrades and a good setup. Learning the ins and outs of setting up a guitar yourself is invaluable. They never come from the factory set up right, no matter if it is a $99 Squire or a $3000 Gibson custom shop. It takes time to really set up a guitar, both the hours spent twiddling the bits and playing the result, and the weeks or months it takes for a new instrument to settle in. It just can't be done at the factory, and having it done at a shop will never be as good as what you could do yourself once you know how.
