I have recently purchased an export aerodyne J and I am quite happy.
I changed the stock bridge for a Hipshot A "Fender edition" and all the hardware to golden, now I am on a particular crusade against noise and hum.
The stock pickups are ok, the P sounds like you would expect and the J bridge sound is also good, I am now considering different options to get rid of the single coil hum and the electrical noises that this bass will pick in some locations, but the sound is solid. If this bass was quiet enough with the stock pickups I wouldn't care changing them.
That sounds like a pretty sweet bass as it is (feedback isn't an issue to me). Would you be willing to trade it? Possibly for my pride and joy, my 1994 Fender "Cowpoke" P-Bass Deluxe?
The only thing wrong with it is the pickguard. Apparently the guy that sold it to me left it in a hot car, and as such the pickguard is warped somewhat and cracked in one place. Also, the active electronics sound great, but the battery life is a tad shorter than i'm used to. Think about it, and let me know. (good review by the way)
