Is it the flat top or the carved top version? I can't tell from the photo.
The carved top version is sonically a Les Paul. The Cadillac I had was an import but it had a real 3/4" maple top and a fairly chunky neck and the big Les Paul neck heel. I wish I still had it. I tried a lot of pickup combos in it. It was killer with either a Super Distortion/PAF combo (any of the PAF-style pickups would be great... Virtual PAF, 36th, or Air Classic), or for a more modern sound, a Crunch Lab/Breed Neck combo.
Oh never mind, I can tell from the photo it's the bolt-on version. It's probably basswood and hit-or-miss on how solid the neck joint is. I say go nuts with it, go for the X2N, D-Activator X, or D-Activator. If you go the X2N route, try a Tone Zone in the neck.
Oh, and I just realized the OP is from 2.5 years ago. Bwahahaha. This is the kind of day I'm gonna have today.
