Back to strings. I decided to try Pyramid M828 Stainless Steel 040/060/080/100 medium scale strings; that length should work well for my 1966 string-thru-body Mustang Bass. I wanted to try brighter stainless roundwounds, and that gauge made sense to me. The current 105 E feels a tad thick and cumbersome. I'd tried Rotosound 90s, but that E was a little too loose and a bit tubby, more so on the '66 that the Vintera. Unfortunately after an exhaustive search, I only found those exact strings in this scale from a European supplier
Saitenmarkt.com. I'm STILL WAITING, and it's killing me because I just just got my '66 setup. Luthier reports the neck is straight as an arrow, the frets all now leveled and barely worn, intonation set, both pots thankfully cleaned up perfectly, and the pickup tested strong (10k), which he lifted a tad. Man it is sweet. It absolutely plays fantastic. But it screams for new strings.
Meanwhile, I bought the La Bella MUS Mustang Flats for my son's Vintera 60s. And I must say, THEY.ARE.AWESOME. They really sound great and are super fun to play, smooth like a fretless. And while they don't get super bright, they do have a rich tone and sound great.
So the jury awaits, but unless I am blown away by the Pyramid's when they finally arrive, I just may have to get a set of La Bella flats for the '66, as well. Peace.
