I've certainly had necks that are deeper... I could happily go a touch deeper on the neck as i'm finding I prefer a more chunky neck these days for whatever reason...
Here's a quote from Bernie regarding the neck:
"It's a pretty thick, chunky neck. It's based on a guitar I used to use called 'The Beast' which many of you will be familiar with. So it's quite deep... It isn't super deep, but you know you've got your hand around it once you get used to it."
Probably one of the most comfortable necks i've played on... Maybe would have liked the frets to be a bit taller. Bending and vibrato are a dream on it though!
