Uses more gain than you.
The Peterson blows the Boss out of the water for accuracy. The regular Korg Pitch Black(+/- 1 cent) is the same as the Boss, while the Pitch Black +(+/- 0.1 cent) is much better.
Damn, and here I was thinking it was only as bad as the TU12, when instead it's even more of a piece of shit. Get rid of the Boss!:noway:Given that it's 30 times as accurate, I'd say it's worth it. I wouldn't get along well with a TU-2, personally. ±3 cents isn't close enough for me, and I don't understand why my $20 Korg tuner can get within one cent, but most pedal tuners settle for ±3. I plan to get a Peterson later this year as I'm doing some rig overhauls.
Well, unless you've got a Conn Strobe.I had a TU-2 and was using it to set up my guitars.
Then i got a StroboStomp, and re-did my intonation, which made me realize how shitty the accuracy of the TU-2 is. My guitars all sound better after setting them up with the Peterson. If you do your own tech work, you MUST have one. Anything else is shite.
