I got the pup yesterday. Fast shipping and great service
First impressions are good. I have only tried it on my practiceamp and in Amplitube (yea I know, it stinks

) Compared to the JB it seems more smooth and balanced. Cant wait to try it out on a real amplifier. I'm gonna do some recordings this evening. I'll report back when I've tested it some more.
Off topic. I found out that my guitar is roted for mulitple pup configurations. It's just one big hole under the pickguard.

The guitar is a US Lonestar Strat. I wonder how this affects sound.
