It’s 4 ping pong delays on clean feeding into each other at different time ratios(1:1, 2:3, etc). The 1st one is always on and you can turn the other 3 on with the foot switches. There is a master tap tempo on the 1st delay then there are individual tap tempos if you want to adjust a specific delay. There is also a master mix button and master feedback button.
Not sure what to add next but I’ll be messing with it for sure!

(1st row = output w/ gain, master feedback and master mix
2nd-5th row = pingpong delay, the white buttons show what rows are active and the red buttons are the tap tempos)
