If you're gonna play, you gotta be in tune, right? Right!
Works for all kinds of instruments, just clip it on and go.
Comes with a guitar, ukulele, violin, and bass preset, but you'll want to stick with "Chromatic"... because that's what the cool kids do. ;-)
One flat, weird looking, watch-style battery INCLUDED!
NOTE: you do not need this if you have an "EQ" model Seagull Merlin, as they come equipped with an onboard tuner!
