The electric upright bass (abbreviated EUB and sometimes also called stick bass) is an electronically amplified version of the double bass that has a minimal or 'skeleton' body. These features greatly reduce the size, weight and in some cases, the cost of the instrument whilst retaining some of the features of a double bass.
In comparison with other electronically-amplified string instruments, eg electric violin/viola/cello, the EUB has been taken up by a wider range of players. The EUB may have become more widely used than the other electonically-amplified string instruments because the double bass is large and hard to transport.
The scale length of EUBs varies: some scales are 42", similar to most double basses, whilst some models have scale lengths of only 35" similar to the bass guitar. The shorter scale can make it easier for bass guitarists to convert to the EUB. Some scales lie between these two extremes. The fingerboard extends over two octaves and usually has side dots for the players reference. Regardless of scale length, the strings are tuned to E0, A1, D1, G1 at the same pitch as the double bass or bass guitar.
As with the double bass, the necks on some EUBs get considerably thicker about half way down from the nut to the bridge. This point is sometimes called the 'heel' of the bass and is where the neck starts to enter the body on an acoustic double bass. Double bass players use this feature as a tactile reference for left hand position.
Most EUBs produce little sound on their own and the string vibrations are amplified usually using piezoelectric pickups located in the bridge. Some EUBs do have a small resonant chamber which changes the tone and response of the instrument. Some models are fitted with magnetic pickups like the bass guitar.
Features of the Ned Steinberger electric upright bass:
The optimum height for most players will be when the (index) finger in the first position (first fret on a fretted instrument) is at the same level as the player's eye. If the bass is higher than this, discomfort may be experienced when playing long passages in the first position. If the bass is too low, the player may need to bend or stretch when attempting to play notes at the higher end of the fingerboard (although not as much as on a double bass).
The strings are plucked with the sides (not the tips or nails as in guitar playing) of the top joints of the index and middle fingers whilst the thumb of the right hand rests against the side of the fingerboard. The strings are plucked usually just below the fingerboard.
In the extreme high positions, where the neck on an EUB gets considerably thicker, the left hand usage can be modified with the whole hand being brought round to the front of the instrument and the thumb taking the place of the index finger. These positions are called the 'thumb positions' in double bass parlance. In these positions, it is necessary to rest the neck of the bass against the players left shoulder in order to support the neck against the pressure of fingers on the strings.
On the shorter scale EUBs, bass guitar fingering can be used over a large portion of the fingerboard and thumb positions may not be necessary. On the longer scale models, due to the larger distances between notes, the double bass (Simandl) fingering method usually has to be used unless the player has unusually large hands.
Higher pitches can be produced on all strings on the EUB before having to employ the 'thumb positions' because there is no body to obstruct acesss. As the scale lengths are sometimes smaller than the double bass, it can be easier to convert from a bass guitar to an EUB than to a double bass because the bass guitar fingerings can be used in most left hand positions. Since the EUB typically does not have a hollow sound chamber, or only includes a small sound chamber, the EUB is less prone to feedback when amplified than the double bass. In order to use a bow with an EUB, the bridge has to be curved like the bridge on a double bass; if not, the strings may not be accessible to the bow.
