Did a lot of drawing and calculating last night. With this body type a sliding pickup is impossible with a 24 fret neck.
Best I can do is a 20 position neck. The sliding plate where the pickup is attached to takes a lot of space and has to be able to obcsure the gap in any position.
I personally don't really like the pickguard.
I would skip the sliding pickup.
And go for this one:
- Artec Mudbucker pickups on the shortie
- EY Guitars 60 repro Humbucker on the fretless
- Ebony fretboard on both necks
- Gotoh Res-o-lite bass tuners. And Gotoh CBX-01 carbon plate tuners for the two octave strings
- Custom Brooks Duo Rail bridge system for the shortie
- Babicz Solo Rails for the 5-string 35" fretless
- Mahogany body
- Maple neck for the shortie
- Mahogany three piece neck for the 5-string 35" fretless
- Volume Artec Neck, Volume Artec brigde, Volume EY, Master Tone
- Two outputs. One of them switched to allow for one output for all pickups
- Three way toggle to choose upper, both or lower bass
- Wine red high gloss finish.
