Should I get a Dean V guitar or a Jackson Rhoads guitar?

I would personally prefer the Jackson but it’s really an individual thing. Try them both out and see which feels best to you.

I’m not a big dean fan, so personally I’d take the Jackson. I’m also more partial to the king V instead of the rhoads… But that’s just me.

If I were forced to choose I would go for the Jackson, it’s exactly like the V except it’s like a more extreme, sexy version. Try and think how comfy it would be to play too. Jackson’s can be heavier than Vs.
