i didn't think of that, thanks. to get the same input level the
oberheim is at 9:00 and the gibson at 12:00, pretty drastic.

when the levels are adjusted well, both units sound identical. but it
takes some time to re-adjust the knobs to the 'sweet' spot, so i guess
the taper of the pots affects how the limiter is going to interact.
kim, how are the new blackface EDPs? do they retain the same A/D-D/A
converters and same preamps? or are they improved versions of the
whiteface EDPs?
