antiquity P90 problem...

[lizhard]

HI I've just put a set of antiquity P90 pick on my Epiphone '56 gold top reissue but I have a problem in difference of the two P.U. .
The bridge position sound really thin and low outpout ,but really big difference.At the same volume on the amplifier the neck position crunch the sound while the bridge sounde really clean and thin.
I try to raise the pole a lot but I didn't get a substantial difference.

Could be a problem of the potentiometer or could be a problem of the pick up?

:yell:

Hmmm... I thought I just answered this question a few hours ago.

If you have a DMM (digital multimeter) check the ohms on a cable plugged into the output jack with the controls all set to 10. Either pickup alone should measure somewhere between 8K and 10k. Both pickups together should measure half of that (4-5k).

If the readings for the bridge pickup are a lot different than that you might have a bad solder joint at one of the pots or in the cable or at the pickup.

If the ohms look okay then there is the possibility that one of the magnets in the P-90 got "flipped". Is this pickup new or used? Normally like poles will repel each other but in a P-90 there is usually a keeper between the two magnets which will acquire the opposite polarity so that the two like poles can face each other. You can check magnetic polarity with a compass (but you would need to take the pickup apart).

Re: antiquity P90 problem...

I've noticed that the Antiquity P-90 in the bridghe postion is really sensitive to it's height. Stick some foam or something under there and get it as close to the strings as possible. It really fattens up once you get it up about 1/4 to 1/8 of an inch away. Then you can fool around with the poles.

Note: the covers are kind of chopped really short for the antiquities. Duncan base plates stick out more than gibbies for some reason. For me to get the pup high and not have the edge of the cover show I had to take some other covers and file down the inside walls so it would fit over the edge of the base plate... kind of hard to explain.
