I left the in line tuners for the clip-on as it gets one pedal off the board, the lighted clip-ons seem more accutrae and are easier to see...I see so many acoustic and electric players using them that maybe the stomp boxe tuners aren't selling as well...but they are a nice pedal...a lot of muti-effects and acoustic guitars have on-board tuners so I have a feeling the TU2 prices will come down but I don't see them going away any time soon.
