Peterson STROBOSTOMP2™ - Strobe Tuner

Manufacturers Details:
The StroboStomp2™ replaces the original Peterson StroboStomp-the world's first Virtual Strobe™ tuner in a stompbox! It features improved battery life; additional Sweetened Tunings™ for electric & acoustic guitar, bass, Dobro®, pedal steel guitar,and electric violin; and offers four user-programmable Sweeteners™. The StroboStomp2's die-cast aluminum chassis features industry standard Neutrik® 1/4" and XLR jacks , blue accent lighting, and is finished in a Titanium Pearl coat that will keep it looking great even after years of getting stomped on!

100% True Bypass is accomplished via a rugged 3PDT stomp switch, which allows the player to mute both regular and DI outputs to allow silent tuning with an incredible 0.1 cent accuracy! Open-string Buzz Feiten settings for guitar, bass, and 12-string are included with drop-and capo-tuning transposition and, if all that is not enough, a built-in active DI (with a power saving mode for longer battery life) for acoustic and bass guitarists. The StroboStomp2 is constructed from heavy-duty die-cast aluminum and even has a 9VDC output to power other pedals!
