I've had this tuner for about a year now and long story short don't buy it lol! Now to the reasons why. I was locking for a strobe tuner as I wanted to work on the intonation of my guitars so I would do a complete set up on my instruments. There were some food suggestions but were over my price range. After some research I've found the Korg Pitchblack Custom. Price was decent specs looked good and it looked sexy. So I bought one as it was supposed True Bypass plus it has the strobe function. First thing I noticed, the strobe function is unusable. I could never get the nite to stabilise and it was giving me a headache. In the semi strobe function it works better as at least I can see where the note is and get the sensitivity of the tuner. After a year or so of using it I noticed it actually affects the tone. I didn't really get it as I was always playing high gain sounds but I was feeling the sound I was getting was a bit more screechy and less full. Finally I got it out of the chain and the tone came back. Put it back in then the tone suck came back. Plus when I turned the volume pot to zero I got some strange noise. Actual noise instead of no sound. I tried it with a fresh battery instead of the power supply I got for it and I even got actual noise in the amp. So it's not a true bypass and the strobe function is unbearable lol. Looks good though.
