It‘s a JB. I picked up my guitar just yesterday. Based on my experiences with other SD pickups and my tube amp, I figured that JB would do the job. Unfortunately, I can neither prove or disprove it cause my amp seems dead. It worked as recent as two weeks ago so I need to look inside or drive back to Thomann.
I was able to play through my Line6 prosessor but I find that the frequency response of Line6 ampsims is not very organic. They sound roughly the same with every humbucker I have.
