Gdub mentioned one the other day but I have to say that I am impressed with this product. I purchased one two wees ago and used it for our two night gig that weekend. First of all, they can be had for about $15 on the internet. My daughter Kari, turned me on to it.
I own several tuners, a couple of strobes and Fender PT 100 and some other chromatic tuners. Most of them require a power source and batteries go dead so I like to plug them into 110. The first thing that I did was check the Snark against one of my strobes. I was blown away by the accuracy. It is dead on. The next thing I did was test it for tuning the low B on my L-2500 and was surprised to see that it picked it up immediately. So far, I'm impressed. I used it on the gig that weekend and it is so easy to use and visible. The display is clear as can be and it is the easiest tuner that I have ever used as it is a clip on, no plug in. The only thing I have not tested is the battery life but I suspect that it will not be an issue. It is a sweet product and would make a great stocking stuffer. Here is a picture and I apologize as my camera is not doing a good job close up.-- Darwin
