Sonic Research Turbo Tuner ST-300

After reading all the rave reviews about this tuner pedal I decided to pull the trigger on it and I have to say that this pedal lives upto those rave reviews. Its accuracy is unlike any other tuner pedal. Even those Peterson tuner pedal look pale compared to this pedal However the thing that surprised me the most is its tracking speed. This pedal tracks in realtime which is impossible to do with DSPs. So I opened up this pedal and what I saw truly surprised me. This pedal doesn't use a DSP to measure your tuning. It uses the analog signal from your guitar to directly drive a LED array stroboscope. It basically a LED array based analog strobe tuner stuffed in a pedal.

This tuner ain't just accurate but also tracks my guitar signal way faster than any other tuner. It's as good (if ain't better) as those standalone strobe tuner units.

I have one for my guitar board an another for my bass. I'd keep just one of them if only because the strobe looks so cool. But since they react so fast and accurately they both get to stay. My guitars have never been better intonated.

My ex-guitar teacher recommended me this tuner pedal instead of PolyTune 3 and I'm glad I listened to her. The tracking speed of this tuner is way faster than PolyTune 3 and its visibility is great too.
