the last one looks way cool but the hands on your watch might pull downward !

(that is if you even wear a watch on your right arm or even wear on in the first place !) i'm sure a rotary switch would take care of all those switchcraft toggles !
the first idea was like the one i had back in the late '70's but in a fretless so as just to emulate an upright sound which i feel the 4000 series naturally has with a higain or toaster. was to be with or without pickguard depending on if i wanted to mount the pickup top side like some rick guitars do and if, back then, i could have special ordered something like that from RICKENBACKER inc.
cool ideas you got there. wish i had the gray matter to do photoshop like jeff and mario, but i can barely type (as "blue man" knows) and i have a lightbulb shaped callus on my index finger from responding to this forum !
