First of all, I love it, but not intuitive. The Freeway switches make more sense. I bought it at 920d Sigler before they sold out and now only use Chinese parts.
Now I only go to their website to get ideas, not to buy anything.
The pro is having all those options and the ability to kick on the series option. The only con is its hard to remember which option does what. Thats why I like the Freeway switch, they make sense. The minihumbucker is awesome and the Bridge pup Excellent. I would go with a hotter middle pup if I were doing it again, but it's nice enough as it is so I don't have a reason to change.
10 year's ago you call the Sigler people and they'd change things for you, the only time I'd buy from them now would be if they Custom made something for me. You could tell them what you want, like dimarzio PUPS, cts pots, Freeway switch and see if they'd make it for you, but don't buy anything stock. The parts are too cheapy.
The money is when the series option is kicked in.
