Based off the ever amazing and (in my opinion) very underrated Boss SL-20!
Left switch sets the tempo. Middle switch cycles through 13 optional rhythms. Must be in analog mode to access them.
(Hold down the bypass and scroll button together until the bottom right square under the screen turns light blue.)
Right switch will bring your guitar into a 50/50 mix beside the ZL-20 effect.
Expression pedal dials in a Octave +/- effect.
Also has a visual metronome on the first page. Some of the beats are kinda weird so it’s not super accurate. Mostly there just for aesthetics.
Enjoy! And feel free to tag me in any videos of you jammin with it!
