It seems there is nothing new inside. It's a standard Boss DM-2 clone with top quality parts! Still a great project to get involved in though. Check the thread out here: http://freestompboxes.org/viewtopic.php?f=7&t=4216
For a schematic, PCB and layout (Much thanks to Bajaman :-) check out his little project folder: http://freestompboxes.org/members/bajaman/Baja/Baja%20Wet%20Cat%20Analog%20Delay/
He calls his version the "Wet Cat" - build it, if you can find the ultra rare MN3005!
P.S On FSB right now there is a buy in of MN3005 chips so if you want one get down the freestompboxes forum and post up :-)
