Nice work on the enclosure, nice design, cool theme, and the burnt knobs gives it a unique look. Just because there’s no spaghetti monster of wires to show off, a gut shot is still helpful for others to see component choices, inner layout spacing, jacks, and overall build quality with everything put together.
Regarding the Delay runaway repeats simply dial back the Repeats to 8:00 where there is only a single repeat and start with that. It only takes a few tweaks from there to get it to three repeats and then you can start harmonizing with yourself while moving through a scale. I rarely have my Repeats past 11:00 unless I am using it for a runaway noises by turning it up and then playing with the Time knob for Spaceship fun.
