The original Little Sister concept is based on a chambered body design.
The mahogany plank is shaped in the outline of the body and then routed from the top with a drill press, removing the wood to create the tonal chamber.
Once the chamber is routed and sanded, the maple top is then glued onto the body.
The Step Sister employs the exact same building and chambering technique, with the only difference being the slightly shorter body design, joining the neck at the 16th fret.
Quite obviously, a chambered bodied guitar will be more resonant than a solid body one, and will influence the electric tone with an added amount of vibrations transduced by the pickups. The fundamental tones will be less ‘forward,' and the lower order harmonics will be more pronounced. A chambered body guitar will also offer a subtle but very musical dynamic compression, with a softer, rounded attack of the notes. The overall sound will be more complex, almost 3D-like.
A solid-body Step Sister will deliver a firmer, bolder tone, with stronger fundamental notes, and a more focused timbre that will cut through the mix. The dynamic response will also be faster, with a more evident attack, compared to the original chambered body Step Sister. A solid-body guitar will also have a slightly higher threshold of ‘stage volume before feedback,' and therefore will be easier to manage in loud playing environments.
To sum up, a chambered body guitar will have a richer, softer and more complex sound quality, and a solid body will have more punch, attack, and focus. A chambered body will enrich your fingerstyle playing, your clean, jazzy, bluesy chords and lead lines, up to some seriously driving classic rock.
A solid body will be dryer and more ‘in your face,' thus very much at home on bigger, louder stages, when you need higher gain sounds, and in harder rock applications.
