Thread revival after trying on several brands of strings. Pizz only, bowing only used for intonation practice and etudes.
The first set I tried was the preinstalled Helicore Hybrid Lights. As a Spirocore Stark user these were a bit floppy for my taste, and the tone was somewhat boingy. Low tension makes for a bit higher action than I'm used to but I could work around it. These strings sound well and play easy. It's a decent preinstalled set that I think many owners will be happy to keep.
Next up was my trusty Pirastro Perpetual set with regular D and G. The tone was very similar to the Helicore Hybrids but less boingy. This set came off for pretty much the same reasons.
Third up: A much loved (=beat up) set of Spirocore Mittels. These felt much better and had better projection with almost no boing. But these were way too e-bassy, and no amount of fiddling with the blend and tone settings could mitigate this. Close but no cigar.
Fourth: A set of Innovation 140P Polychrome hybrid strings. These strings are darker in character and have a vintage vibe on the SLB300. Mid/high tension means I can bottom out the bridge screws for lower action, and it's an easy transition from the Spirocore Starks on my Chadwick hybrid.
The only drawback with this set is that the E sounds a bit, I dunno, sterile. I can live with it and it'll probably sit well in the bands I play in (jazz band and bluegrass), but when I have the time I'll try other low E strings. Maybe a Spirocore Mittel?
