I have a few problems with this Bass Guitar which I bought from England's GAK music store under 1 year ago.

Problem 1:
When I first used the Bass, there was a terrible electrical buzz in the signal when the strings were not touched with my hand. I did a simple continuity check and found the strings and bridge plate were not earthed to the main earth point at all. When I removed the strings, bridge plate, and pickgaurd to inspect, I found that the earth wire that is supposed to sit under the bridge was receeded into its little channel and this hole was also full of green coloured corrosion. I am kicking myself now since I didn't take a photo, instead I cleaned it all up, re-exposed a decent amount of wire at the end of the cable and replaced it under the bridge plate to get a good connection to the bridge and strings. Worked a treat - strings now earthed correctly - clean signal. Fine for now.


Problem 2:
I am using this bass for home recording. I use an Apogee Duet, iMAC and Logic Pro 8.
NOw after about 8 months I am getting this problem. After approx 20 minutes of slapping (which is what this Bass is good for) the signal becomes noisey and contains some distortion - yukk. If I then unplug the cable (Fender Platinum by the way), turn the pots, flick the pickup selector switch a few times - replug the Bass into the system, the noise and distortion is gone and the signal is back to its clean normal self.

My thinking is some sort of static build up in the active electronics?? Again perhaps an earth problem...but where? Dirty pots??


Problem 3:
The pickup blend dial seems to only have any tonal effect in the first 2-3 degrees of movement from its central rest position. Further movements to either endstop(s) yields practically no tone differential at all. This 'observation' I have noticed from the start. Perhaps just a feature.


Problem 4:
I bought this from an English music store, and I live in Germany. I really dont want to have to post it back there (probably at my expense), get them to check it, and post it back saying theres nothing wrong..


So, does anyone have some useful tipps or thoughts. There is an ellectrical wiring diagram for this Bass on this Fender website, so if your wanting to give some advice here, check it out and leave a note

Thanks a lot
Julian
