QWIK TUNE- GP-1 Guitar Professor The Qwik Tune Guitar Professor (GP-1) is the all-in-one accessory that every guitar and bass player needs! This small device includes a guitar/bass tuner, chord finder (with over 250 chords), and a pitch pipe! The guitar tuner can easily tune your acoustic, electric or bass guitar without plugging in by using the microphone (just tune your instrument with the GP-1 directly in front of it) or plug directly into the GP-1 for a more accurate tune. The chord finder gives you access to over 250 chord fingerings at the touch of a button! (1) First search by chord letter and (C, C#, D, D#, E, F, F#, G, G#, A, A#, B) then choose what type of chord you want - such as Major, Minor, Diminished, Augmented, or Suspended (2) Then narrow down what chord and/or fingering you'd like by scrolling through multiple versions and fingering such as 5th, 6th, 7th, 9th, add 9, add 11, add 13, etc. The pitch pipe plays low E, A, D, G, B and High E, which can come in handy... and is great for ear training.
