PG's Joe Coffey is On Location in Nashville, TN, for Summer NAMM '09 where he visits the N-Tune booth. In this segment, we get to check out N-Tune's newest product, the Artist Series On-board Tuner. Its an on-board chromatic tuner that is specially designed to fit most electric guitars and basses that have a 3-way toggle switch and humbucker pickups. By conveniently placing the N-Tune display ring around the toggle switch, the Artist Series tuner is activated by pulling up your volume control knob, which also mutes the output signal of your instrument while tuning.
