Bass guitar

• 1. Introduction

  ›

  The bass guitar sits at the bottom of the guitar family, anchoring the sound of popular music for decades with a voice no other instrument quite matches. In Seattle, Washington, during the 1930s, a musician and inventor named Paul Tutmarc built the very first electric bass in its modern form. He made it fretted and four-stringed, designed to be played horizontally like a standard guitar. Only around 100 of these instruments were ever made. Then, in October 1951, a company called Fender began mass-producing the Precision Bass, and everything changed. How did an instrument with roots in a small Seattle workshop become the backbone of rock, jazz, and popular music worldwide? What engineering choices made it so much easier to play than the instruments it replaced? And who were the players that first picked it up and proved what it could do?

• 2. Tutmarc and the First Electric Bass

  ›

  Paul Tutmarc's 1935 sales catalog for his company Audiovox listed the "Model 736 Bass Fiddle": a solid body electric bass guitar with four strings, a single pickup, and a defined scale length. Audiovox also sold a companion "Model 236" bass amplifier to go with it. Tutmarc had solved a real problem. The double bass, the instrument that had previously filled the low-end role, is what acousticians call "acoustically imperfect", much like the viola. For a double bass to achieve ideal acoustic resonance, its body would need to be twice the size of a cello, making it essentially unplayable. So the double bass was built smaller than physics demanded, and the low notes suffered for it. Tutmarc's electric design bypassed that compromise entirely. Electromagnetic pickups could amplify the low frequencies the wooden body could not produce on its own. Despite this elegant solution, the instrument remained a curiosity during Tutmarc's lifetime. It would take Leo Fender to bring the electric bass to the world.

• 3. Fender Changes Everything

  ›

  Leo Fender and George Fullerton developed the first mass-produced electric bass guitar in the 1950s, and the Precision Bass that resulted transformed how working musicians operated. The earliest version featured a simple, uncontoured slab body and a single coil pickup, closely resembling the Fender Telecaster guitar. By 1957, the design had evolved: the body edges were beveled for comfort, and the pickup was changed to a split coil design with two separate halves, giving it a look closer to the Fender Stratocaster. The practical advantages over the upright bass were significant. The electric bass was far lighter, far smaller, and much easier to transport. When amplified, it resisted audio feedback far better than an acoustic instrument. The frets, which the Precision name directly referenced, allowed players to hit pitches accurately without the trained ear an upright bass demands. Guitarist-trained musicians found the transition much more natural. In 1953, Monk Montgomery became the first bassist to tour with the Fender bass, playing in Lionel Hampton's postwar big band. Montgomery may also have been the first to record with it, at a session on the 2nd of July, 1953, with the Art Farmer Septet. Bill Black, who played with Elvis Presley, and James Jamerson both switched from upright bass to the Fender Precision Bass around 1957. Among the early pioneers who came to the instrument from guitar were Joe Osborn and Paul McCartney.

• 4. Gibson, Höfner, and the Competition

  ›

  Gibson released the first short-scale violin-shaped electric bass, the EB-1, in 1953. It included an extendable end pin so a player could perform either upright or horizontally. In 1958, Gibson followed with the maple arched-top EB-2, described in its own catalog as a "hollow-body electric bass that features a Bass/Baritone pushbutton for two different tonal characteristics". The EB-0 arrived in 1959, resembling a Gibson SG in outline, though the earliest versions had a body shape closer to the double-cutaway Les Paul Special. Gibson did not produce a bass with a standard 34-inch scale until 1963, when it released the Thunderbird. The company's short-scale instruments typically ran 30.5 inches, a noticeably different feel from the Fender approach. Meanwhile, at the German trade fair Musikmesse Frankfurt in 1956, luthier Walter Höfner, a second-generation violin maker, debuted the Höfner 500/1. Built using violin construction techniques, its distinctive viola shape would become one of the most recognized silhouettes in music history, specifically because Paul McCartney adopted it. The instrument became known simply as the "Beatle bass". In 1957, Rickenbacker introduced the model 4000, the first bass built with a neck-through-body design, meaning the neck wood ran continuously through the entire body.

• 5. The 1960s Expansion

  ›

  Rock music's explosion in the 1960s pulled many more manufacturers into the bass market, including Yamaha, Teisco, and Guyatone. Fender introduced the Jazz Bass in 1960, initially marketed as the "Deluxe Bass". Its body used an offset waist design first seen on the Jazzmaster guitar, intended to improve comfort when playing seated. Unlike the Precision's single pickup, the Jazz Bass carried two single-coil pickups. Fender also produced the Mustang Bass, a 30-inch scale-length instrument aimed at players who found the 34-inch Jazz and Precision necks too long. The Fender VI, a 6-string bass tuned one octave below standard guitar tuning, arrived in 1961 and was briefly favored by Jack Bruce of Cream. Gibson introduced its short-scale EB-3 in 1961 as well, also used by Bruce. The EB-3 included a "mini-humbucker" at the bridge position. On the experimental end of the decade, the first commercial fretless bass guitar appeared in 1966: the Ampeg AUB-1. By the late 1960s, eight-string basses with four octave-paired courses had arrived, such as the Hagström H8, a configuration similar in concept to a 12-string guitar. The Ampeg AUB-1's fretless design would quietly influence players who wanted the expressive, sliding quality of a double bass without its size.

• 6. Boutique Basses and Active Electronics

  ›

  In 1972, a company called Alembic established what became known as the "boutique" or "high-end" category of electric bass guitars. Players such as Phil Lesh, Jack Casady, and Stanley Clarke were among those associated with these expensive, custom-built instruments. Alembic incorporated premium hand-finished wood bodies, multi-laminate neck-through-body construction, and graphite necks. The company also pioneered onboard electronics for pre-amplification and equalization. Active electronics work by boosting the instrument's output and giving the player control over specific frequency ranges, both amplifying and cutting high and low registers for a more flexible tonal response. Music Man Instruments, founded by Tom Walker, Forrest White, and Leo Fender, introduced the StingRay in 1974. It was the first widely produced bass to include active powered electronics built directly into the instrument. Basses with active systems typically include a preamplifier and separate knobs for adjusting low and high frequencies. The UK company Wal began producing its own line of active basses in 1976. In the mid-1970s, five-string basses with a very low B string began appearing. In 1975, bassist Anthony Jackson commissioned luthier Carl Thompson to build a six-string bass tuned, from low to high, B0, E1, A1, D2, G2, C3, adding both a low B and a high C string to the standard four-string arrangement.

• 7. Strings, Pickups, and Scale

  ›

  Bass guitar strings are built from two components: a central wire core made of steel, nickel, or an alloy, and a winding wire wrapped around it. The winding material and its cross-sectional shape determine a great deal about how a bass sounds. Roundwound strings use a circular cross-section winding; flatwound strings use a rounded-square cross-section. Halfwound strings, sometimes called groundwound, sit between the two. Coated strings add a synthetic layer over the surface. Tapewound strings replace the metal winding with a plastic one over a metal core. Taperwound strings take a different approach: the end of the string narrows so the exposed core rests directly on the bridge saddle with no winding at the contact point. The choice of winding style can push a bass toward or away from certain musical genres. Pickups sit on the body beneath the strings and convert string vibrations into interference within a magnetic field, which is then translated into an electrical signal sent to an amplifier. On a modern four-string electric bass, scale length, meaning the vibrating string length between the nut and the bridge saddle, falls into defined categories: 30 inches or less is short scale, 32 inches is medium scale, 34 inches is the standard, and 35 inches is long scale. The longer 35-inch scale is more common on five-string and larger basses, where it helps the low B string produce better resonance. That low B is tuned to B0, a pitch the four-string layout at standard tuning simply cannot reach.
