Re: cort-m-custom-m900
It doesn't sound that much like a Paul - IMO it sounds better. The bridge JB isn't much like a Gibson PAF, but the neck pup is. The hollowness really adds to the sound, IMO - as long as you don't play loud with lots of gain - then it'll REALLY add to the sound ;-). This is a full hollow guitar; it has no center block. I have two of the earlier Korean made M800 ones (no piezo) and an Indonesian M Custom. I put a Stetsbar trem, Sperzels, and steel frets on the Custom - that's how much I like it. Fit and finish are slightly better on the Korean ones, but they're all well made.
The older M800 and some M900s had Mighty mite pickups instead of Duncans. They have a more traditional sound and are IMO good pickups. The non-piezo M800 bridges have a different stud spacing than a Paul, so you can't easily put an FRX or Stetsbar on one. The Piezo-equipped M900 and M Custom work fine. The headstock design isn't great for holding tuning with a trem, though.
