I was looking for a tuner that can handle the low frequencies of a Bass(even drop bass tunings). I have used our guitarist's korg pitchblack which was really good, so i was about to get the the simple one but got the advance for the same price. It's even more precise than the standard korg pitchblack. True bypass. No noise, everything is fine. Solid box, big,bright,durable screen. Excellent addition to any pedalboard. I can only reccomend this tuner pedal.
