The Fender PT-100 Pedal Tuner is as straightforward as they come, giving you a single input for your guitar or bass and two outputs -- one that constantly sends signal down the rest of your chain and one that mutes when the tuner is engaged. This chromatic tuner features an easy-to-read LED display shows you how far off you are from the target note, and is built into a rugged die-cast enclosure to ensure it'll keep on ticking gig after gig.
