I have this deluxe memory man in the old enclosure that won’t make any effect sound at all. It powers on and the pre-amp is still working along with all the leds but it wont make any echo/vibrato/chorus noise. I’m not exactly sure how to tell what year it is but I bought it new in 2004. Anyone have any ideas on this?
Thanks

Could be a couple of things.  Bad delay IC, bad clock IC, bad solder joints, etc.  Best to get it to a tech.
