The demonator shape was a signature model for David Vincent from Morbid Angel.
The MM series (of which this is one) were cheaper versions of the original.
the mm 1 pickup model retailed around £200, and the 2 pup active version around £300.
When I endorsed Dean I had a single pup version and the Thru neck version.
The shape -to me - was thunderbird meets moosrite, and I still love my neck thru.
£130 is about all they go for these days, certainly in this configuration
