I'm a stickler for having a guitar in tune and the intonation has to be right...I've been using a Boss TU-2 for many years and still it left something to be desired,several months ago somebody here posted a link to a demonstration on youtube for the Turbo Tuner from Sonic Research.
I had to try it and got one last week...I love it,the guitar is closer than I have ever had it before....the tuner is new so I don't know how it's going to hold up to use in the future,and the Boss is tough,so we'll see.
I have absolutely no connections to Sonic Research,just passing along something for gear freaks like me to consider....here's the link.
The model I bought is the ST-200
