How are the SITs? I'm curious about them, but never see them anywhere in person.
We had a music store here in Ashland, Oregon who stocked SITs, and my buddy in Nashville, Tennessee reports that Brian Barrett from the LowEnd shop loves them, so it sounds like you have a great excuse to drop into a music store next time you travel, as some stores do stock them. For science!
I had not knowingly played SITs myself until I got to try a fresh set of Power Wound nickel roundwounds on @Isaac_James ’s’s’s new Rickenbacker last summer. He had mentioned them as a reasonably priced option for cobbling together custom sets from singles, and also that they had a consistently smooth feel while retaining plenty of high end. The former attribute appeals to me as someone playing weird instruments in weird tunings, and the second attribute appeals to me as someone attempting to transfer a number of flamenco guitar techniques reliant on fingernails to bass instruments. Between that and string sage @michael_t ’s consistent praise for SITs, it seemed like time to finally give them a try when I saw they offer packaged six-string sets in .120/.100/.080/.060/.040/.030.
I went with the Fusion Wounds since Isaac said they sounded especially angry

and going from the standard gauge NYXLs to the custom light gauge Fusion Wounds was like night and day. I can see why many players like the NYXLs, especially when it comes to feel, but they don’t really do “angry” at all (as I had recently experienced when I tried a fresh set on my Ibanez ATK). The Fusion Wounds, especially with the Nordstrand Big Singles, feel friendly to the fingers and fingernails
and absolutely angry at everything else. I consider passive tone knobs purely decorative, and pretty much only ever use onboard preamps to boost highs, but even I find myself backing off the highs a bit with these. They have almost the same kind of crunchy high end as fresh bronze roundwounds for acoustic bass guitars. I get a good “angry piano” sound from the neck pickup with a modest boost at 700hz on the onboard preamp, with a tiny boost to lows and a tiny cut to highs if I’m feeling particular.
I suspect the highs on the Fusion Wounds would sound too harsh for most players, and I will likely try the same gauge in the more conventional Power Wounds next, but I do like these quite a bit for my purposes. Anyone who wants a lot of zing should consider the Fusion Wounds.
