Hi Alberto, is it possible to get the adjustable stringspacing near to 17 mm (max. 18 mm) ?? 
with the distance of the G string i mean - the distance from body to string - not from neck to string !! It only can be between 7 to 10 mm --and not 0,9 mm !! 
This is important for me - cause - if the distance is too big, I get stuck with my forefinger during slapping ! 
Do you ship to Germany - and do you are interested in trade ( + cash ) with : 
1. Cliff Bordwell 5-string fretless   - 3 Band EQ with frequenz switch, activ + passiv ( www.cbbasses.com ) or 
2. Spector 5-string fretted Euro LX-Custom -neck through - Poplar Burl, activ, tone pump 
 
both instruments in very very mint conditions
