One of the Customer bought a straight Edwards Tenor and want to add a O.E.Thayer on the body.
So I take out the original neckpipe and separtate all the connection joints. Then the most difficult thing is put all the new parts and valve together. It takes me 4 to 5 hours to set up and put the valve on the body.
After set up, I need to solder all the new valve connections. make all the tunning slide and valve trigger smooth like factory setting.
