Installed in a Japanese Les Paul (neck position), the pickup has that typical Gibson bluesy/jazzy warmth as hoped for, and with a nice top end. Plenty of output, I set the height lower to balance with a 498T in the bridge. I have a 90's Gibson LP studio and compared the two neck sounds - very similar with just a little more top end clarity on the new pickup. The 4 conductor wiring with a push pull pot switches to single coil for chords or picked stuff, or even just for reducing level while keeping the clarity - you could do series/parallel or out of phase too if you like. I installed a cover, (49mm pole spacing) , which was easy and still has the output and treble. To summarise, a great juicy vintage sounding neck pickup with all the wiring options, thanks.
