Yeah don't buy in too much to the PAF thing about the Custom. There are some notes or undertones that may remind you of some older PAF type tones and the overall tone is a bit more timeless than say the DD. But the pick up is a MONSTER, especially for tight metal/thrash chugging on those low strings. It does not have the output of the DD so you might need to use more distortion on your amp or use a pedal. But it does down tuned C# very well for me. Other than that, the DD is probably the route to go. The JB may be a bit too loose for what you want.
