3 PCM 41 units in for repairs.  These are some of my favourite delays, many fond memories playing with these in feedback.  

I just acquired one, and before this weekend have never used one. I have a few questions about this unit...

1.. If I mix the the signal totally 'wet' it sounds like there is nothing past 5000 hz coming out. If it is mixed 'dry' the signal sonds fine. Does this sound right?
