The MXR Turbo Tuner is the only tuner you’ll ever need. Built around the core engine of the original Sonic Research Turbo Tuner, this pedal brings modern versatility to the gold standard in strobe tuning. Sonic Research engineered it to deliver the same tour-grade precision and speed as the original, accurate to a fraction of a cent. It’s all built to the roadworthy standard that defines both Sonic Research and MXR.
