Send Offer This is a unique guitar Not only is it a headless guitar, but it has fanned frets and more importantly it comes with a built in fx unit. The Fx Unit is rechargable with USB C cable and you use the GTRS app on your phone to edit your sounds. You can have a whole amp rig built into this with overdrive pedals going out, or chorus, flanger etc. It has built in Amp Models and Cabinet Models too where you are even able to use this before a power amp or even in the (fx loop) fx return which will bypass the preamp section in your amplifier. It also comes with a looper pedal, which also allows you to change between presets.
