Ya, when I was talking with Siminoff I thought myself into it. Roger talked about the signal delay in the digital ones and indicated that they repeat every second which makes getting a tape on a sound board difficult. Where the analog ones are instantaneous and give you better results. So, I just thought why by something when I will just want upgrade later anyways.....goofy! Shane |

I think Roger must be thinking about some older digital tuners. The Peterson Virtual strobes are real time with no delay. What they can't do however is show any hint of harmonics and overtones. They only read the fundamental. Have you looked in to the Peterson Strobosoft program? I believe the full version includes a spectrum analyzer and oscilliscope. I've never seen a strobe tuner as having much use in tuning a soundboard. The whole idea of strobe tuners is to view the motion of the disc pattern if the pitch varies from correct. In the case of tapping a top or a banjo head, the tone is so short lived that you could never really see if the pattern is stable or in motion. Seems like it may briefly appear and disappear at best. For tuning anything with such rapid decay I find it hard to beat a tuning fork or a string (or the pitch generator on the VSAM). If you wanted to measure with more precision including overtones you should look in to an audio spectrum analyzer program. Many of these allow you to record peak frequencies, show real time or plot charts for things like decay. |

Ahhhhh! See now I have a bunch more research to do! I have to defer to your better judgement David, I know tha you have published on this stuff. The tuner is on its way so I will be giving it a try and if it don't work for tuning plates then I gues I have an expensive but accurate tuner for setting up intonation and the like. Once I get it and start to use it and research a bit more, I am positive I will looking for a bunch of good advise! Like has often been said here, the more I know the more I know I don't know....but ya gotta start somewhere. So thanks! Shane |
