I have always wanted to pick up an old memory man analog delay(echo)/chorus, like the one that 'The Edge' used to use on his early stuff. I notice EH still makes them, but like most pedals the old ones are more desirable and supposed to sound better. Are the new ones any good, or are they horrible? Right now I use a Boss DD-6 for my delay and really don't like it that much. I want a more analog and warm sounding delay(echo). Also how would I tell a new vs and old memory man? What are some good alternatives instead?
