Versatile Tuner for a great price.
I remember when there was no such thing as a digital tuner. In those days, mechanical strobe tuners were the 'super standard' that all others were compared to, but they were prohibitively expensive...Not something that most people could justify.
Forward forty years, and we have the Peterson SP-1 StroboPlus. This thing is outstanding! It only takes a few minutes to figure out the controls, it's fast, and very easy to read. You can create virtually any tunings you can dream up, AND store them. I tried a couple of the sweetened tunings, and checked out the tone generator. Cool features, all. The built-in microphone is really sensitive, and the 1/4" IN/OUT jacks make it convenient to tune and immediately play to check how they sound through an amp.
Now for my only complaint, and the reason for the sub-5 star rating.
This thing was $140. As stated above, I know how much of a value this super accurate strobe tuner is all by itself, but $40 extra to unlock the metronome? I guess I won't be doing that anytime soon.
All in all, this is a fantastic tuner.
