Construction Chapman Sticks have been made from many materials. The first were made from hardwoods, most from
ironwood, but some from
ebony and other exotic woods, until the early 1980s. The next group was made from an injection-molded
polycarbonate resin through 1989. These were followed by one-piece hardwood structures with an adjustable truss rod, and for a time from 2001 to the mid-to-late 2000s (although not currently available), the "Stick XG" (Extended Graphite) was made of structural graphite, continuous strand carbon fiber. Today, they are made from laminated hardwoods (including
padauk,
Indian rosewood, tarara,
maple,
wenge, and
mahogany), and laminated
bamboo, as well as
graphite. In contrast to the guitar or bass, the Stick is set up with very little
relief in the fretboard. It is very flat compared to a guitar, which has a slight bow. Combined with a long scale length, stainless steel pyramidal fret rails, very low string action, and very sensitive pickups, this setup is advantageous to the tapping style of play. The rear surface of the instrument is not curved like a guitar neck, but has deep-beveled edges (also a design trademark of the Stick).
Tuning The original tuning, now called "Classic" by the instrument's players, consists of five bass strings (six on the Grand Sticks), tuned upwards in
all-fifths tuning, with the low string in the middle of the fretboard, and five melody strings (6 on Grand Stick), tuned upwards (this means from lowest-pitched string to highest-pitched string) in
all-fourths tuning, again with the low string in the middle of the fretboard. However, the hardware is fully adjustable to accommodate any gauge string at any position, allowing many possible tunings or string configurations. On the 36"-scale instrument, notes can range from low C (above B on a 5-string bass) to high D (a whole step below the high E string on guitar). On the two guitar-scale models (Alto Stick and Stick Guitar), the notes range from F below guitar low E to F# above guitar high E. Tuning configurations may change depending on the player's style: a player playing as a lead instrument will choose an overall higher pitch tuning, with more separation or overlap between the melody and bass courses. The stringing/tuning configuration of the Chapman Stick is advantageous to the player who wishes to play large, fully voiced chords with close inner-note relationships. In contrast to a standard guitar, where one tends to "run out of options" within a particular fingering, the Stick tuning results in up to four or even five octaves of note choices under each hand's fretting position. The classic tuning shows another advantage as well: The
regular tunings in
fourths and
fifths remain consistent in each of the two parts of the instrument; regular tunings facilitate learning by beginners, as well as transposition and improvisation by advanced players. Also, the bass/melody division allows
microtonal tunings. The manufacturer's website has more detailed information on tunings.
Electronics The Stick is available with passive or active
pickup modules. Customized
Roland GK-3 pickups are available for the treble or bass side of the instrument, allowing the instrument to trigger or control one or two guitar
synthesizers such as the
Roland GR-20 or
Axon AX-100, and also to drive other
MIDI instruments or
sequencers chained to the guitar synthesizer. The hammer-on style of playing produces a rising waveform transient that is easily tracked by this type of device. Standard output is two-channel, through a
TRS 1/4" phone connector, with bass and melody courses output separately. There are separate volume controls for bass and melody. The ACTV-2 and PASV-4 pickup modules also have mono operation modes. The Stick can be plugged into any standard
guitar amp or
bass amplifier, to good effect. However, because of the very high impedance of the passive pickups, an instrument
preamp is often employed, especially for full-range amplification systems (
PA system,
keyboard amps, etc.). British musician
Nick Beggs uses a Grand Stick, fully MIDI-capable of triggering from both bass and melody strings. He has named this modified instrument the "Virtual Stick".
Models There are eight models of the Chapman Stick. Some string configurations are mentioned below, but current production models offer any tuning within physical limitations of stringing: • The Stick (10 strings, 5 melody & 5 bass/6 melody & 4 bass, other custom tunings and set-ups, 36" scale length) • The Railboard (10 strings, a 1-piece CNC-cut thru-neck aluminum beam with 9 pieces bolted-on including headstock, bridge, new R-Block pickup module, 34" scale) • Grand Stick (12 strings, 6 melody & 6 bass/7 melody & 5 bass, other custom tunings and set-ups, 36" scale length) • 10-String Grand Stick (10 strings installed on a wooden or laminated bamboo "blanks" for the Grand Stick 12-string model, thus creating a wider fretboard & string spacing for a 10-string Stick. Center-to-center string spacing is 0.350" as opposed to 0.315" on standard 10-string Sticks. The space between the "melody" & "bass" groups of strings is also wider, at 0.500" instead of the standard 0.430". Same 5 melody & 5 bass/6 melody & 4 bass, custom tunings and set-ups & 36" scale length as the standard 10-string Stick) • Stick Bass (SB8) (8 strings, undivided "straight 4ths" B-Bb
bass guitar or B-A
electric guitar intervals tuning, standard Stick 4 melody & 4 bass, other custom tunings and set-ups, 36" scale length) •
NS/Stick (8 strings set up for plucking, strumming, or tapping in standard bass or guitar intervals, standard Stick 5 melody & 5 bass, other custom tunings and set-ups; co-invented by Chapman &
Ned Steinberger, 34" scale length) • Alto Stick (10 strings, 5 melody + 5 accompaniment, with shorter scale length for a more
guitar-like range, 26.5" scale length) • Stick Guitar (12 strings, 2 groups of 6, with shorter scale length for a more
guitar-like range, 26.5" scale length) The Stick, Grand Stick, and Stick Bass are 36"-scale, but the older production models were 34" scale. Stick Enterprises has also manufactured some custom and limited-run instruments: • SB7 Stick Bass – Original "Stick Bass" model with string-spacing close to the current 10-string Chapman Stick, which is narrower than the SB8 8-string Stick Bass. 2 Bartolini bass pickups (1 "Soapbar" & 1 "Single Coil"-sized: only 1 selectable at a time) with mono-only output as opposed to virtually all the previously built and current to the original & upgraded over time passive "Stickup", newer active EMG "ACTV-2" Block, passive Villex "PASV-4" and "R-Block" railboard pickup modules, all of which have stereo-or-mono output. Only one production run completed in 1996–97 until replaced by the more Stick-like SB8 in March 1998. Only one Production Run of this particular Stick model was built before being replaced by the SB8 Stick Bass. • The Acoustick – an acoustic version of the Chapman Stick made for Bob Culbertson. • StickXBL – A prototype Stick with body construction by
BassLab using a hollow "tunable composite" material. Only a small number of these prototypes exist. ==List of notable players and ensembles==
