Question: when was the first electric instrument that Mashasha played made?

full_context: Document 1: Mandolin: The instrument was primarily used in an ensemble setting well into the 1930s, and although the fad died out at the beginning of the 1930s, the instruments that were developed for the orchestra found a new home in bluegrass. The famous Lloyd Loar Master Model from Gibson (1923) was designed to boost the flagging interest in mandolin ensembles, with little success. However, The "Loar" became the defining instrument of bluegrass music when Bill Monroe purchased F-5 S/N 73987 in a Florida barbershop in 1943 and popularized it as his main instrument.
Document 2: Höfner 500/1: The Höfner 500/1 violin bass (nicknamed the "Beatle bass" or "Cavern bass") is a hollow-bodied bass guitar manufactured by Höfner under several varieties. It was introduced in the mid-1950s and gained celebrity status during the 1960s as one of the primary basses used by Paul McCartney of The Beatles.
Document 3: Solid body: The origins of the solid body electric guitar are confusing. The first commercially available solid body electric Spanish guitar was produced by the Rickenbacker company in 1931. Les Paul, a guitarist, is often erroneously credited with inventing the first solid body, but Fender is often incorrectly credited as the first to commercially market a solid body electric guitar, which itself was based on a design by Merle Travis. Also it is reported that around the same time (1940) a solid body was created by Jamaican musician and inventor, Hedley Jones. In the 1940s, Les Paul created a guitar called the ``Log, ''which came`` from the 4'' by 4 ''solid block of pine which the guitarist had inserted between the sawed halves of the body that he'd just dismembered. He then carefully re-joined the neck to the pine log, using some metal brackets.'' He then put some pickups that he designed on it. He soon went to companies asking if they would buy his guitar. They turned him down. However, after the Fender Telecaster electric guitar became popular, the Gibson company contacted him and had him endorse a model named after him, The Les Paul guitar. It came out in 1952.

Document 5: Bass guitar: In the 1930s, musician and inventor Paul Tutmarc from Seattle, Washington, who was manufacturing lap steel guitars, developed the first electric string bass in its modern form, a fretted instrument designed to be played horizontally. The 1935 sales catalog for Tutmarc's electronic musical instrument company, Audiovox, featured his ``Model 736 Bass Fiddle '', a four - stringed, solid - bodied, fretted electric bass instrument with a 30 ⁄ - inch (775 - millimetre) scale length. The adoption of a guitar's body shape made the instrument easier to hold and transport than any of the existing stringed bass instruments. The addition of frets enabled bassists to play in tune more easily than on fretless acoustic or electric upright basses. Around 100 of these instruments were made during this period.
Document 6: Music Man Bongo: The Bongo is a model of bass guitar manufactured by Music Man, a division of Ernie Ball. It was first introduced at the NAMM Show on March 21, 2003.

It is equipped with an 18-volt 4-band preamp (except on the single-pickup model, which has a 3-band preamp; single-pickup models with piezo bridges have a 4-band preamp) designed by Dudley Gimpel with help from Cliff Hugo and other Music Man artists. It also sports a sleek, carved basswood body with high-gloss polyester finish and a satin-finish painted 34" scale maple neck with rosewood fingerboard (pau ferro on lined or unlined fretless, ebony on both fretted and fretless "stealth" basses) featuring 24 high-profile wide frets and crescent moon-shaped position inlays. These basses are generally known for their dual humbucking pickup configuration, as they are the first twin humbucker-equipped models released by Music Man since the introduction of their Sabre and Cutlass bass guitars in the late 1970s.

They are shorter and wider than the standard Neapolitan mandolin, with a shallow back. The instruments have 6 strings, 3 wire treble-strings and 3 gut or wire-wrapped-silk bass-strings.
