I got a pitchblack a while ago, I was between that and the Boss pretty much. The pitchblack is really easy to read. I actually read it without my glasses on and I'm practically blind.
I haet the BOSS tuner. It does it in fucking string number so if your used to chromatic like every other fucking tuner ever made, it gets confusing. you could be at the wrong pitch and it will say like 3. that's not musical information at all so what the fuck? it does have a chromatic mode, but why have to switch to it? gay.
i have a fender pedal tuner, i love it.
i also have a planet waves tuner i got for free with a box of strings a long time ago. it has a built in bracket that can be used as a stand or to hang it from an acoustic soundhole. very cool.
