This Is Awesome: The Korg PitchJack Tuner
Tuning your electric guitar or bass generally required a quarter inch cable. No longer. The Korg PitchJack totally eliminates the cable with a one plug device that jacks right into your guitar. Available in three colors (black, white, or red) this micro tuner has adjustable angles and appropriate LED’s that denote string and tuning.
For $20, this is a great solution for those of you needing a quick tuning fix on the go. I’m sold.
