I needed a tuner for my guitar effects pedalboard that was easy to read, use, wouldn't take up much space, and built to last. The 4 display modes are nice. Pick what you like. Standard, strobe, half-strobe, or mirror. It can also be calibrated for non-standard pitch, (comes set to standard A440) can be powered with a 9V battery, (comes with one) or a 9V adaptor, and the Pitchblack has a power pass-through so you can power other pedals from it with a daisy-chain if you have the optional Korg A30950 power supply. It's true hardwire bypass so no signal drain in your effects chain when not in use. No pops or noise when stepping/turning it on or off. Very accurate tuner. Very well built: no cheap aspects at all. I am very happy with this tuner and Target's price is as good as you can find anywhere. Any guitar or bass player will love this tuner, pro or beginner. [...]. . . .
