Finally achieved the dream of owning a Zon fretless thanks to fellow BC'er Skinner. Top bass and top chap - it now takes pride of place along with my Sei fretless.
Just wanted to post my appreciation for the effort and care shown by Skinner in the sale of his fab Zon Sonus fretless to me today. Went above and beyond in getting the bass to me and sent video on request of the bass in action prior to the sale. Top bass and top chap!
Worth a look - thanks! I suspect not as I didn’t have this problem in the previous bass these pickups/electronics were in, but that was some years ago so I may be mis remembering!
Interestingly, swapping the pickups around on the blend pot reversed the issue - the pronounced hum is now on the opposite side, indicating that the issue follows the pickup.
Thanks everyone- really good advice all round! I’ll probably try to swap the pickups on the blend to confirm whether it’s a blend or pup issue, but sounding like a new blend pot may be required.
No. The hum is not present when 100% bridge. Turning the pot back then gradually introduces the hum, through 50% blend increasing hum as you get to 100% neck
No problem -pic of the blend pot before I disconnected the neck pickup - hot wire goes to centre lug and the ground braid is soldered to the same lug as the bridge ground.
