Hello everyone. I am currently having built a 7 string guitar with scales ranging between 27 and 25 ''. I have noticed that the positioning of the monorails at the bridge does not follow a straight line. http://www.sweetwater.com/images/items/750/RGIF7BKS-large.jpg As you can see, the forth and fifth's string monorail position seems to be slightly different than the line of the rest strings' monorails.. I hope I made my self understood. Does anyone have any knowledge on this matter. Thanks and cheers!!! Syd.
