Semi-hollow guitars with a center block behave much like solid bodies. Fully hollow archtops have a floating bridge and a top that responds to the strings, so a slightly heavier gauge can help drive the top.
How to choose:
- Semi-hollow for rock, blues or pop: .010–.046 or .011–.050 roundwounds.
- Warmer, vintage voice: pure nickel.
- Jazz on a full archtop: flatwounds in .011–.050 or .012–.052.
- Feedback at high volume: that's mostly about the guitar and amp, not the strings.
On a floating bridge, change one string at a time so the bridge stays put. Big gauge changes may need the bridge height and intonation adjusted.
S.I.T. options:
- S1046 and S1150 in Power Wound Nickel
- PN1150 and PN1252 in Power Groove Pure Nickel
- F1150 Light and F1252 Medium in Power Flat Flatwound
