DOD r-880 analog delay
Digitech 1002 stompbox delay
Ibanez DE-7 stompbox echo/delay
As soon as I face up to the reality of committing my lovely analog noise to digital, I'm going to make some mp3's and an article on cassette looping techniques...I'm still finding new possibilities. plus it's cheap! my (all used) entire setup above cost less then $250...
