I may. What I have is 5-strings - a Sadowsky MV5 and a Lakland DJ5 - and the problem is they are of different size. So that I cannot try Nordstrands on Lakland and/or Aeros in Sadowsky. Also to be fair I'll need fresh strings. But perhaps I can fit shorter Nordstrands in longer Fender-size covers. This weekend I'll look into it.
I recently did a lot of research on replacement pickups for my jazz bass and wound up with Aero Series 1 pickups. I was going for a retro sound with lots of bottom and was strongly advised by some TB "experts" that Aeros were the way to go. Without having heard the Nordstrands, I'm thinking the Aeros may have a thicker bottom end.
IMHO Aeros are a bit "flat" to my experience (no real pronounced frequency in the mids or highs) even though the bass is big and huge (bass is needed but mids are the added trick of the trade for me)
There is an element of 'RAW' that the Aero Type 1 has that most other J pickups do not. It's a great pickup IMO! Another to consider is the JBX4 from www.vintagevibeguitars.com similar character but with a very good shielding system that cut's noise down a lot. Nicely priced as well ...
I had a set of Aeros in my DJ 4 and they felt boomy to me, flat midrange, with a nice raw top end. I would certainly go for the Nordies. I'll be waiting anxiously for the comparison clips hinted at above!
