John Mayer’s Boss TU-2 Chromatic Tuner
Obviously not really an effect, but still worth pointing out is that John used a Boss TU-2 tuner on his Trio-era (2005) pedalboard. Many people want to replicate that exact sound and go for the same exact pedals that Mayer had at that time, so it doesn’t hurt to have it listed here.
