Got a 1979 Pro1e recently.. was fitted with a Wal custom neck at some point, very nice.
The serial number is not listed in the Wal notebook along with 3 others of the same period... some kind of custom order or something
Apparently Pete Stevens wanted to buy it back from the previous owner...!
Anyway, mine goes up to 11... do all the Pro1's do this?
Edit: Pardon my ignorance!
