Welcome to the forum!
If it helps at all, I describe the settings like this:
The early EB-3s up thru late-1971 used a circuit design that would result in:
Position 1 - Neck pickup with lowpass filtering (heavy lows, not much in the way of mids or highs)
Position 2 - Bridge pickup (wide open, no filtering)
Position 3 - Bridge pickup, and neck pickup with "choke" circuit applied (thin nasal sound)
Position 4 - Neck pickup with "choke" circuit applied (thin nasal sound)
The late-1971 and up basses used a different variation of that circuit:
Position 1 - Neck pickup (wide open, no filtering)
Position 2 - Bridge pickup (wide open, no filtering)
Position 3 - Bridge pickup, and neck pickup (wide open, no filtering)
Position 4 - Neck pickup with "choke" circuit applied (thin nasal sound)
Thanks for your reply Chromium!! As you have described position 4 (thin / nasal), that is certainly consistent with what I head when I play tested the EB3 in the store.
Please clarify one thing for me though. In the description of the 1978 model by Gibson (as posted by Fly Guitars), position 4 is described as a "midrange notch". Perhaps it is just semantics, but I would expect a midrange notch to dip midrange frequencies only, and leave the highs and lows in tact.
Here is the link to Fly Guitars I was referring to: http://www.flyguitars.com/gibson/bass/EB3_controls.php
Thanks!
