Just made a visit to the headquarters of SonoTone Strings to try out their new, round-wound nickel strings. I love me some Pyramid nickel classics - or at least I used to. Had a fairly fresh set of 10-46 Pyramids on my ES-330 when I went in, and was anxious to see how the SonoTones would compare to them. We played the 330 amped for a reference, and then, with it still amped, we changed the strings, starting with the low E. I could hear the difference immediately just from that one string. When we had the whole set on, my mind was blown. The tone was rich, dimensional, and perfectly balanced. They produced a warm, woody low end with the neck pickup, and an aggressive, biting high end with the bridge PU - without a trace of those ice pick-y spikes you can get from the high E string. Sound was clear and articulate, yet still warm and rich. The tonal range from bridge PU to neck PU was phenomenal - every position and knob change produced a "best ever" tone. String feel and tension was perfect - they played like butter, made bends easy, and held tuning really tenaciously. Better than my Pyramids - and a good deal cheaper. WAY better than any other round core nickel strings I've tried, from any brand. I left with 5 sets and started calling friends immediately. Bonus for me: got to play the proprietor's ES-335 with SonoTone hex cores and his mind-blowing Super 400 with SonoTone Jazz Strings, which I think will be perfect for people who like the idea of 3-D sounding flatwounds . I don't know exactly how you can get ahold of SonoTone strings, but I'm sure the interwebz can help. I won't say 'trust me' (because why should you?), but if you try these strings, you'll thank me.
