Pyramid 145 Single String bass guitar

Does the job for Drop C ish

Somewhat dull sounding. Won't do the job if you're looking to go Drop A# or lower, even on a multiscale

Fits most bridges

I've been using this string in through-body bridges as with regular top-loading bridges with no issues. The winding near the ball is quite neat, so the string will fit as long as the bridge accommodates the .145 diameter of the string itself. Enlarging the nut slot will be required on most instruments, though (this can be done in a pinch by using a spare .145 string as a makeshift file)

There's enough winding length to easily accommodate 35" scale length basses, or 34" string through body. There's about 1" of full-size winding behind the nut on my Ibanez BTB, so 36" might also be doable depending on bridge style.

Soundwise, I've found Pyramid SS strings to be slightly less brilliant than the competition. On the other hand, the surface of the strings is quite smooth, so these won't eat your fingertips as bad as some other brands. I go through a lot of these and have gotten a few dud strings, so I'd say these aren't as consistently good as D'Addarios and such, but this is purely anecdotal.
