hello everyone!
strange situation after picking up my guitar from the repair shop (set up + fret levelling).
First it's a Fender Jazzmaster Custom Shop (Japan) The Ventures limited edition and I believe it carries Seymour Duncans JM1 (B and N)
The tech tells me over the phone that the neck pickup is demagnetized to which I ask what are my options and get as a reply that there's a tech who could re-work the magnets
So, I think... maybe it was like that forever and I did not notice before, or just like it the way it is.
I pick up the guitar and bring it home and there is something going on with the neck pick up. It sounds quieter than the bridge's and it's kind of uneven with less gain on the 3rd and 4th strings.
I poked the poles with a small allen key and get a sound from all 6, however when i do the same on the neck pickup i notice that the magnets attraction force is bigger.
As I have recorded something with that same guitar earlier this week I decided to compare wave files (fortunately I recorded rhythm guitars straight to the board using the Neck pickup on the left channel and the Bridge on the right one).
I set up the levels so that the neck pickup matches the level from the old recording and when i try the bridge pickup i se it's noticeably quieter. about 10 dB RMS (an 3 dB quieter peaks)
I'm a little bit confused as the guy says he double checked the wiring.
Summarizing:
- sudden drop in gain on 1 pickup in the course of 3 days (-10 dB RMS, -3 dB peaks). maybe the pick up was much closer to the strings before? (in any case the difference now with the bridge pickup is of about 9 dB RMS)
- magnet attraction force noticeably different and smaller on neck pickup (maybe they are supposed to be like that by design? the strings vibrate less closer to the bridge and the PU needs to seat higher and maybe the magnets to be stronger as well?)
- the PU selector works good, no strange noises when switching PUs (I deoxited it myself a few days ago along with the tone and volume pots)
i'm thinking about strange magnetic fields the guitar could have been exposed too and my car is hybrid, the battery is in the back and the guitar was in the trunk... but it's not the first time.
any ideas?
thanks!
