A fun unit from Befaco, their Crush delay version 3.
A good digital delay, and of course since it's from Befaco it's not a one trick pony, also has the CRUSH side of things which gives you some serious crunchiness if you want it With a feedback circuit that goes on for days.
Not a hard build, but LOTS of parts so will keep you busy for a while.
And one small issue with the power connector interfering with some jack legs, but workable.
