on the specs, SRFF low B is said to have 35.5" scale. But when I measured my SRFF806, the low B actually had scale length which longer than that. I forgot the exact number, IIRC it almost reached 36".
Did you measure from the nut to the 12th fret and double the result or from the nut to the bridge? The industry standard is twice the nut-to-12th-fret distance.
