Used with a little bit of forthought the Petterson can do as good or better a job as any of the hot names on the market. You just have to think a bit more about what you are doing with it. Given any given frequency.... it can identify whether a string has a partial tuned to that frequency as good as any thing else. Cheers RicB Ron, I've had a Peterson 490 ST. Don't go there. If anyone wants it I'll sell it for 50% off of new with case & pedal.
