I’ve found that short-scales can be a bit touchy about strings- you can only increase string diameter so much, before it starts to do weird things to the upper harmonics and intonation. At the same time, steel-core strings don’t sound great much below 30-35lb per string, even if you pluck very lightly.
I’ve been on a bit of a string odysseys after picking up an EHB1005SMS. I bought mine used, with Kalium stainless balanced 136’s on it. They felt OK, but sounded a bit mid-heavy and dull, and the B string sounded hollow, as though it needed more tension.
I put a .145 D’Addario Nickel XL single on in place of the B, and it improved the tension, tone and feel over the Kaliums. Still, it sounded pretty dark, and didn’t think it complememented the stock electronics.
Next, I tried a set of DR Black Beauties, 45-125. The B string didn’t sound as loose and flubby as I expected, and the overall tone seemed well-balanced. They worked OK with a gentle touch, and intonation well.
Still, the B string wasn’t as focused as I wanted, and I thought I noted a slight deadness at the third fret on the A string.
Next, I tried a few mixed sets of D’addario Nickel XL’s. The EXL165 set (reg light/med bottom 45/65/85/105) looked OK on paper with the 120 from a set of EXL160BT’s, but while they sound bright and crisp, they were too loose.
that prompted me to check out the first 3 strings of the EXL160BT’s (50, 67, 90) with the .105 from the EXL165’s and my 145. A 110 would have been better for the E, giving the whole set a nearly perfect 40lb average tension.
Still, this has been the best set so far. Dynamically responsive, even string to string, crisp, and just scooped enough to offset the nasal sound of the stock electronics.
The only trouble is, the extra harmonic detail really brings our that dead spot on the C in first position.
Talking to other owners, dead spots on headless basses aren’t that uncommon, but if an SMS has one, it usually seems to be between the 7th and 12th frets on the G string. My bass seems the exception, with such a strong node way down in the “money notes”.
I hope to do a few experiments this weekend, to see if I can fix it. If so, I think that this is an excellent string set, especially if you’re trying to stick with the stock electronics.
PS: some people have complained about having difficulty cutting strings without scratching or denting the face of the headstock. I found that using compound-leverage 7-8” diagonal cutters made for a cleaner and more controlled cut than smallish flush-cut wire cutters.
These are great:
