Wow, that's a gorgeous guitar. I :wub: the S-series.
I've got a Dimarzio ToneZone - Air Norton combo in my S540LTD, and especially the Air Norton in the neck position is great in that guitar. Together with the middle singlecoil it gets some awesome cleans, and the smooth lead tones are great in the neck position. Some people think the ToneZone is too dark for a mahogany guitar, but I quite like it.
