I have one of the old chrome (big one, looks kinda like a toaster) Morley flangers with the integrated expression pedal, and I've been trying to figure out exactly what the five internal trim pots control. The three external knobs as well, for that matter. The guy I bought it from had spray painted it black at some point, realized his stupidity, and stripped all of the paint off, causing the lettering on the outside to go with it. I've been stuck with this thing for quite awhile, and I've yet to find a setting for all eight knobs that allows for useful sounds. I was wondering if anyone has had experience with this beast, and if they could help me out identifying some of the controls.
