So these are some renderings of a bass I'm designing using Art of Illusion, its a 35.25" scale 19mm string spacing five string, based on a Carvin NT5 neck, with aluminum body wings It is not a fretless I just haven't taken the time to put frets in. I am planning on winding the pickups my self, they are Double J type humbuckers with 1/4" magnets in a standard arrangement on the South coil, and 5/16" individual magnets on the North coil. With the controls I am essentially wiring 3 telecasters with 4 way switches, they are then individually buffered and sent to a pickup selector switch. So it goes Pickup-> 4 way rotary switch -> Volume/ Tone -> Buffer-> Summing Resitors -> 8 way rotary Selector Switch -> Output. 4 way switches 1 South Coil 2 Humbucking Series 3 Humbucking Parallel 4 North Coil 8 way switch 1 Bridge 2 Bridge + Middle 3 Middle 4 Middle + Neck 5 Neck 6 Neck + Bridge 7 All on 8 Muted
