Well, I received the replacement Aerodyne for the noisy one and it's the same. It's a little less noisy and a little less noise when letting go of the strings but I'll just say this, I have 8 other basses, old 80s passives, actives, newer passives and actives, one with an active pup and active pre, and none of them are noisy like these 2 new Aerodynes. A matter of fact, my others are dead quiet and the Kramer with an active pup and pre having a slight hiss, is about 1/3 the noise of the Aerodynes. Both P and J pups are equally as noisy, maybe the J just a little more. I'm being picky and very critical here. I don't see the noise being a problem in a playing or even a recording environment. I believe it's a shielding problem since it's worse closer to the amp. The further away from the amp and the noise is almost non existent. Again, my other basses are quiet right in front of the amp. Others have said their shielding job fixed it. OK, enough complaining, the first thing I noticed right off was the incredible sustain this bass has. They both have really good sustain so it's safe to say, the new ones are built this way. I wish I had an older one to compare to see the post 2015 differences. Anyway, I like the way the new Aerodyne feels, plays, sounds and looks. I can see this bass becoming one of my favorites. I'm keeping it.
