Some buildings have been aerodynamically designed so that convection via ducts and interior spaces eliminates any need for electric fans.

Some contemporary bluegrass bands favor the electric bass, because it is easier to transport than the large and somewhat fragile upright bass.

Some popular bands decided to anchor their sound with an upright bass instead of an electric bass.

Some of the earliest electric guitars adapted hollow bodied acoustic instruments and used tungsten pickups.

Some electric guitar and electric bass guitar models feature piezoelectric pickups, which function as transducers to provide a sound closer to that of an acoustic guitar with the flip of a switch or knob, rather than switching guitars.

Some contemporary players of these modern electric harps, especially solid body and minimalist design instruments, have been able to add the advantage of movement on stage into their musical performance.

Some types of brushless DC electric motors use Hall effect sensors to detect the position of the rotor and feed that information to the motor controller.

Some electric locomotives can also operate off battery power to enable short journeys or shunting on non-electrified lines or yards.

Some musicians play electric mandolins through amplifiers.

Some switches are used to isolate electric power from a system, providing a visible point of isolation that can be padlocked if necessary to prevent accidental operation of a machine during maintenance, or to prevent electric shock.

Some vehicles can also be equipped with hydraulic or electric retarders which have an advantage of near silent operation.

Some of these early bulbs had such flaws as an extremely short life, high expense to produce, and high electric current drawn, making them difficult to apply on a large scale commercially.

Some variable nozzle turbochargers use a rotary electric actuator, which uses a direct stepper motor to open and close the vanes, rather than pneumatic controllers that operate based on air pressure.

Some electric power systems use the free-wheeling drive propeller to generate charge through the drive motor when sailing, but this system, including the design of the propeller and any gearing, cannot be optimised for both functions.

Some pollution and use of other energy sources are inevitable during these stages of the boat's life and electric boats are no exception.

Some regulators regard electric transmission to be a natural monopoly and there are moves in many countries to separately regulate transmission ( see electricity market ).

Some common instruments in the string family are guitar, sitar, rabab, electric bass, violin, viola, cello, double bass, banjo, mandolin, ukulele, bouzouki, and harp.

* Electric motors and generators: Some electric motors rely upon a combination of an electromagnet and a permanent magnet, and, much like loudspeakers, they convert electric energy into mechanical energy.

Some drafting tables incorporate electric motors to provide the up and down and angle adjustment of the drafting table surface.

Some manufacturers of residential cooking appliances now offer indoor grills for home use, either incorporated into a stovetop or as standalone electric devices.

Some fusion jazz groups use a lightweight, stripped-down electric upright bass rather than a double bass.

Some luthiers have increasingly focused their attention on the needs of fingerstylists and have developed unique guitars for this style of playing.

Some modern guitars are made of polycarbonate materials.

Some harp guitars also feature much higher pitch strings strung below the traditional guitar strings.

Some piezo-equipped guitars use what is known as a hexaphonic pickup.

Some acoustic and classical guitars only have a single strap button at the bottom of the body — the other end must be tied onto the headstock, above the nut and below the machine heads.

Some acoustic and classical guitars come with no strap buttons at all.

* Some notes on Resonator guitars,

Some songs on Die Kleinen und die Bösen ( The Small Ones and the Evil Ones ), featured thrashed guitars, electronic screeching, and hammered drums while Gabi screamed and ululated.

Some of his Stratocaster guitars feature a Fishman PowerBridge piezo pick-up system to simulate acoustic guitar tones.

( Some special edition guitars used these trems prior to their reintroduction, however the vibratos used were NOS, rather than production runs ) These two vibratos, whether old or new, bear a mark of Floyd Rose Licensing, as they are produced using the same tooling, by Japanese guitar parts manufacturer Gotoh.

Some time in the 1970s, Martin bought LEVIN guitars, and around 200 D-18's were apparently built in Sweden ; they are stamped LD-18.

Some luthiers and repairmen attribute this to a gradual trend of misplacing the bridge on these guitars: the same jigs for bridge placement were used throughout the history of each model's production.

Some guitars which have humbucking pickups feature " coil splits ", which allow the pickups to act as " pseudo-single " coils by either short-circuiting or bypassing one coil.

Some guitars ( e. g. the Peavey T-60 and the Fender Classic Player Jaguar HH ) make use of a variable coil split circuit that allows the guitarist to dial a variable amount of signal from the second coil, from pure single-coil to full humbucker and everything in-between.

Some examples of this are the Fender Jazz Bass, introduced in 1960, which has used a pair of single coil pickups, one near the bridge and another one about half way between the bridge and the neck, and many Stratocaster style guitars, which often have 3 pickups with the middle one reversed electrically and magnetically.

Some modern Roma musicians, like Ando Drom, Romani Rota and Kalyi Jag have added modern instruments like guitars to the Roma style, while Gyula Babos ' Project Romani has used elements of avant-garde jazz.

Some twelve-string guitars have non-traditional structural supports to prevent or postpone such a fate, at the expense of appearance and tone.

Some hard rock and progressive rock musicians use double-necked guitars, which have both six-string and twelve-string components, allowing the guitarist easy transition between different sounds.

Some of the Gibson employees who did not want to move their homes and families to Tennessee started production of guitars under a new name, " Heritage ," which was likely meant to stake a claim to their guitar-making tradition.

* Some guitars of Lacote show Sor's signature: Fernando Sor, the Catalan guitarist living in Paris has signed a number of guitars by René Lacôte – examples now survive in the Edinburgh University Collection of Historic Musical Instruments, Cat.

Some lap steel guitars can be converted between lap and fretted playing, or are modified versions of conventional guitars — the only difference is usually string height.
