Berhringer TU300 vs BOSS TU-2 vs Peterson VS-S vs TC Electronics Polytune. I have been buying these for tuners over the past year whenever they were at a good used price. Finally I have them to do a head to head shootout to determine which is the best tuner. These four tuners are probably the four most popular pedal tuners on the market. I tested these tuners in bypass mode so the signal should be clean in the chain and powered them from the same daisy chain. I used two guitars to test with, the Godin XTSA Electric guitar and the Taylor 314ce. Please let me know which of these four tuners you think did the best. Berhringer TU300, BOSS TU-2, Peterson VS-S or TC Electronics Polytune.
