Since 2011 German bass luthier Warwick built several fretless Thumb NT 7 basses for Jeroen Paul Thesseling, featuring a 34-inch (864 mm) scale with subcontra tuning F♯–B–E–A–D–G–C . Yves Carbonne developed ten- and twelve-string fretless subbass guitars. In 2017 a 13 string bass tuned Ab00–Gb–Db–B–E–A–D–G–C–F–Bb–Eb–Ab4 was built by Prometeus guitars giving the fullest range to a string instrument allowable by current string technology.
In the 1930s, musician and inventor Paul Tutmarc of Seattle, Washington, 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 1⁄2-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.
Yet another form is the portable digital piano which is what appear to be combining the capabilities of stage pianos, but with additional features similar to a conventional digital keyboard. These digital pianos are mostly designed for various purposes such as home, studio, classroom, stage or personal use. It is similar in form to a stage piano, but much lighter in weight, and having a more compact size. Unlike stage pianos, portable digital pianos were commonly equipped with built-in amplification and loudspeakers, usually has lower cost than other types, and its sound quality were often comparable or similar to that of a regular digital keyboards due to a simpler sound synthesis system, though some models, still utilize a similar sound engine as the more advanced model lineups of the same manufacturer.
The long scale necks on Leo Fender's basses—with a scale length (distance between nut and bridge) of 34 inches (864 mm) — set the standard for electric basses, although 30-inch (762 mm) "short scale" instruments, such as the Höfner 500/1 "violin bass" played by Paul McCartney, and the Fender Mustang Bass are also common. Short scale instruments use the same E-A-D-G tuning as a regular long scale instrument. Short scale instruments are good choices for bassists with smaller hands, such as children or young teens who are just starting the instrument. While 35-inch (889 mm), 35 1⁄2-inch (902 mm), and 36-inch (914 mm) scale lengths were once only available in "boutique" instruments, in the 2000s (decade), many manufacturers began offering these "extra long" scale lengths. This extra long scale provides a higher string tension, which may yield a more defined, deep tone on the low "B" string of five- and six-stringed instruments (or detuned four-string basses).
