I'm thinking about getting rid of my PitchBlack, actually--not because of tuning, but due to some weird noise; I run it from the 'tuner out' on my Ernie Ball JR Volume pedal, so i can tune either with the output still active, or rock the volume pedal back, and have silent tuning-- the output of the pitchblack isn't actually connected, just the input. However, when the tuner is on, there is some noise that is fed from the input of the unit, back to the output of the volume pedal, and then down the main output which feeds the amp... a bit weird, and quite annoying once you've noticed it! I'm going to try a buffer between the volume pedal and the tuner to see if that helps first, as I do like the pitchblack. Wez, nice to see that the pitchblack holds well compared with a strobe! Boring video, but interesting at the same time ;)
