i wouldnt say the V is the perfect shape... its very gimmicky, and good if you wanna show off. but its not exactly practical.
in terms of tone, it really lacks; compare it to a les paul standard, or a PRS custom, and it really sounds flat, and boring. theres no shift in the tone, and because of the body size, it sounds very tinny, with a quick falloff.
they do play pretty well, and they are usually pretty light. i know they are the favorite of a lot of lead players because of that. but i think the soloist does a much better job in terms of practicality and tone.
just my 2 cents.
though i think if i buy a jackson, ill be getting a custom shop model with the soloist style body... and it wont cost less than 4000 sterling.
