I think you are right man. The extra weight probably adds a bit of that girth that benefits the overall tone.Hey Roman.
I have that skulls demartini. I also have a snake demartini. The skulls San dimas body and the snake is the smaller/lighter soloist. I believe the extra weight really adds to the tone. Either way the rtm pickup is a little hotter than a jb. Not much but does help it separate from the normal jb. I like it. Both guitars are awesome but the skulls wins out.
God,I want one of those snakeskins so badly.I've had 2 snakeskin loved both of them great necks. That pick up is very hot!
