I love the look of those but I can't get along with how they sound (Why for example does the bridge pickup have only half the output of the neck pickup?) and the 4001 body shape looks overweight with a guitar neck. I have this Metallica T-shirt with a Rickenbacker bass picture and I was going "Smaller scale than an actual one, I could work with this." So I traced that picture and now I'm in the process of creating a routing template. My plan is, normal start style neck (with a modified Headstock), mahogany body, P-90's and a wrap around tail. I'll keep you guys informed on how this comes along.
