I've been without a pedal tuner for about a year now, and I'm shopping for an inexpensive option. There seems to be a plethora of cheap Chinese pedals now, along with the standard Korg, TC, Peterson, and the like. I see used Korg DT-10's going for around $30, and remember about ten years ago them being the bees knees for pedal tuning. Anybody know how an older Korg pedal tuner would compare to a brand new Joyo, Donnner, or similar cheapo pedal as far as accuracy and bypass? Have pedal tuners gotten better, or are they just cheaper to make?
