Hi guys.... A quick question (i think) for any of you who have experience of Charvel and Jackson neck profiles.

Take for example the Charvel Custom Shop San Dimas and the Jackson Dinky DK1 (USA Select Series) :

Both have a bolt on quarter sawn maple neck... But what is the difference in neck profiles?
Is the Jackson a thinner profile or are both very similar?

Thanks in advance.
