I think it's happening to me, i had my lacs neck based on an old jem neck, and love the way they play, and then am obsessed by old universes to the point where I am not playing any of my other 7strings...
Maybe it's familiarity?
i always play my LP more than my other guitars (except when it took a dive and broke a tuner, then i played my C7 all the time) because the neck just feels like home. i remember the grin i had when my buddy replaced my shot toggle on her and handed it back, and i was just playing and grinning haha.
just get that neck on alll your guitars
