Don't own a King V, but here's my LTD DV8-R next to a Les Paul. Should bring some clarity as to the sheer size of these things, lol https://imgur.com/7Q2gTpm
I actually have a similar question about the size difference between the DV8 and the Dean VMNT. I've never really been able to get my hands on a VMNT, so I have no basis for size comparison. I already have a massive, unwieldy, ridiculously awesome guitar. If the VMNT is a little smaller I might be interested in one of those. Anyone who has experience with one, please feel free to chime in, haha
For what its worth I have a King V KV2F the F has different humbuckers and jumbo frets.......I LOVE THIS GUITAR! I picked it up for a £1.3k it's £3.2k new, it's had 1 dink replaired which is really hard to notice, but this guitar is the holy grail for me.......I have a hand built PRS Custom 24 which is lovely also but I'd go for the Jackson!
