I just rechecked and it's the same; positions 1-3 select bridge + single, pos 4 selects all, pos 5 neck only.. Once I get the schematic from A.J I'll try to find a licensed EBMM place in Budapest and take it to them.
Resurrecting this thread to give you all an update. Went to this place in Budapest Vintage'52 Hangszerviz who are a luthier shop and and were recommended by the local Hungarian EBMM wholesale dealer Sicamber Trade - hangszer kiegszitok - Joyo - Artec - SnapJack I highly recommend this place for anyone in the area, they know what they're doing. Thanks again to EBMM CS for hooking me up.
