Bartolini 59j4 custom wound #4 winding ????

[johnnybass01]

I found a new set of these pickups and they are a long/ short set that will fit my bass , and they are brand new at a great price , the only info I can find is that this is the same neck pickup in the modulus flea 5 string i can't find anything out anything else about them. any help would be great.

The difference between #1 and #3 voicing is brightness. One might assume that a #4 would be even brighter than the #3, but there is no official reference to them (that I found) in the Bartolini catalog.
