It was shared to me by my good friend and ex-bandmate on how to drop tune using the Zoom G1Four. I've been using this pedal for very long time. I never tried until he mentioned it to me.
Also after discovering how to drop tune, I started to re-invent and use it to up tune. Like a virtual capo.
If you want to know how I did it, here's the link to my membership videos: https://youtu.be/i_my36qtVSM?si=zSl-KDPbYn08mONB
