Didn't find too much on a search, but I hope this isn't wasting bandwidth. Just picked up a used Blade 4 string J type (it was the one with the rounder crowns, for those that responded to my "fret crown" thread). Anyway, i used it on a gig, and it played and sounded great. The preamp (I prefer passive, but this sounded good) had a nice mid-bump switch on the front that was nice for solos. Emailed Blade and they sent me a diagram for the preamp in 12 hours. Pretty flexible, and very solid bass...I was quite impressed. Anybody else tried these basses?
