*** whoops!  Posted in wrong section!  Mods please feel free to move.  Apologies :(

...there's only 1 x mn3205 in there.  Are these pedals using a .2 second chip and just extending it beyond its delay time?  I haven't used this pedal since I was 15, I cant remember the delay time you can get out of it, but I could swear it was longer then 200-300ms...

aah....ok!  Looking forward to messing around with it tonight.  Might make a good test pedal as the bbd has a socket and trimpots as well.

He adjusts and compares the ibanez and maxon versions.  It gets more interesting on page 2.

That's interesting, ill have to read through the whole thing.  One difference between my pedal and the 2 in the review is mines from the 80's :D Its old school. 

I was comparing it last night to my aquaboy, and I think either the calibration has drifted, or it was never set up properly to start off with.  Its ridiculous short (slap on max).  200ms as measure by my sound recorder, isn't slap.  You should be able to hear the first delay signal with a very slight pause following your original signal.  Anyway, its got trimpots so I might mess around with it and see what happens  :o
