I've got an old Washburn hb-35 that I found in a dusty old shop. Nicest fretboard I've seen in quite some time. Beautiful instrument, well made, beautiful fretwork, grover tuners etc. But everything else is wrong with it. Only one position on the selector switch works. bridge pick-up cuts in and out. All the pots either crackle or cause the most ungodly hum in my amp. My thought is to suck it up and replace all the wiring and pickups, switch, pots. But good grief, seems like a bear of a job. Tying dental floss to the selector switch so I can pull the new one back into position, etc. So... anyone done a job like this? Any tips? Thanks in advance!
