The neck profile in the Little Sister and Step Sister comes from countless nights of playing all the vintage guitars we could put our hands on, making measurements, sanding prototypes and drinking coffee.
The Standard Neck profile features a comfortable, vintage-inspired “Soft V Shape” in the first frets, to ease the hand in reaching around the neck, for the typical blues techniques of thumb fretting the low notes on the 6th string.
Moving up the neck, the shape gradually evolves to a more rounded shape for easier access to the upper area of the fingerboard, granting a full-bodied profile that will fill most hands just right.
The taper of the Standard Neck profile has an overall thickness of 22.6mm (0.89”) at the 1st fret and grows just slightly to 24.3mm (0.96”) at the 10th fret.
The Slim Neck, optional on both the Little Sister Private Build and the Step Sister Private Build, has a slightly shallower and more rounded profile, less of a V and more of a C, with a thickness of 21.5mm (0.86”) at the 1st fret, and 23.2mm (0.91”) at the 10th fret. For how subtle the difference may seem, the feel of the Slim Neck is noticeably sleeker, for a more modern, contemporary fretting hand technique, offering more comfortable support for the thumb in extended chord positions, and faster, virtuosic solo runs.
Tonally there is no significant difference between the two, as the mass of the Slim neck is only very marginally smaller than the mass of the Standard one. Ultimately it is a matter of personal taste and habit, as both shapes offer the same stability, ruggedness, and tone.
