I got this pickup I trhink it is called the bass max. Fits in the wing. Well for about a year now it has been on the bass side of the bridge with a shim in there to hold it in place. Well I have always had trouble with bad tone and feedback with it? Well a couple of weeks ago I just decided to try it in the treble side of the bridge wing without a shim. OH my it is the best tone I have ever heard? Is it supposed to be on the treble side?
