Query: Not happy with your tuners performance with acoustic instruments? Then get one of these!

I have a Boss TU-12 that I use to tune acoustic guitar, acoustic bass, mandolin and ukulele. The tuner never gave me stable readings, especially with the uke.The TP-2 solved all of those problems. It provides a very steady reading on the tuner needle and really makes accurate tuning acoustic instruments very easy. It works pretty well on my electric guitars also!The only down side to this pickup is that the cable is a little thin and I'm not sure how it will stand up to constant stage use.
