Definitions

  • This invention relates to an improved electric guitar and is more especially directed at providing an electric guitar which can optionally be used as an acoustic or amplified acoustic guitar.
  • the electric guitar has been constructed with a solid body to which electromagnetic pickups have been mounted for sensing vibrations of the strings to produce a signal which can be amplified as the instrument output. While very popular and of considerable use for certain of the more popular types of modern music, such guitars cannot produce any substantial degree of audible sound if used without the electrical pickup and amplification and also do not provide the tone and musical qualities required of a conventional acoustic guitar which is used for playing more traditional and classical types of guitar music. Attempts have been made to amplify the music obtained from acoustic guitars, which have a thin-walled hollow body, by mounting.
  • the present invention is directed at providing a guitar which has the more beneficial characteristics of both the amplified acoustic and conventional electric guitars and yet which can also be used without any electrical amplification whatsoever to produce a direct sound of good quality when the player requires, as for example when playing in a confined space or when practising.
  • an electric guitar comprising a hollow body with a neck rigidly attached thereto for tensioning strings attached to a bridge carried on the front face of the body, said body comprising a rigid back and sides defining the rear and sides of an internal cavity and a flexible front table covering the cavity and to which the bridge is secured, an aperture being provided through said table with an electric pickup securely mounted to the rigid back of the body within the cavity projecting through the aperture to a location for cooperation with the guitar strings.
  • one pickup, the lead pickup is provided closely adjacent the bridge with a second, rhythm, pickup being provided between the first pickup and the neck.
  • the second pickup can be provided projecting from a portion of the table rigidly secured to the metal of the body so that the vibrating part of the table which is used when the guitar is in its acoustic mode is that portion of the table which covers a cavity through which is rigidly secured the first, lead, pickup to project through the aperture in the table.
  • a transducer for allowing the guitar to be used to provide an output similar to that of an amplified acoustic guitar can be secured to the undersurface of the flexible table within the cavity in the body.
  • an additional switch may be provided on the front of the guitar for controlling whether the guitar is being used in its electric or amplified acoustic mode.
  • the cover be made of a fairly resilient material, for example spruce, and also be provided with suitable stiffening on its rear side by a system of spaced bracing.
  • the bridge can then be relatively massive, being secured through the table to the bracing, with the result that the strings of the instrument are adequately supported for use in electric mode and provide a good quality sound vibration to the vibrating table in the acoustic mode of the guitar,
  • a guitar having a body from which projects a neck 11 provided with the usual peg head 10. Strings are tensioned from the peg head over a fret board on the neck 11 to a bridge 16 mounted on the front table 23 of the guitar body. Projecting from the guitar body are a rhythm pickup 12 and a lead pickup 13 for sensing vibrations of the strings when the guitar is being used in its electric mode. Also mounted on the front table 23 of the guitar are the various controls illustrated as a three position pickup selector switch 17 for use when the guitar is in its electric mode, the switch being movable between three positions in which either the lead pickup 13 only, both pickups or the rhythm pickup 12 only are in operation. A second switch 14 is actuatable between positions to control whether the guitar is in its electric or its amplified acoustic mode.
  • Knobs 19 and 21 are volume control knobs operable respectively when the guitar is in its amplified acoustic and electric modes.
  • the knob 18 is a tone control for the rhythm pickup and it also has a push-pull switch to control a conventional variable coil tap arrangement for the rhythm pickup.
  • the knob 20 serves a similar function for controlling operation of the lead pickup.
  • the body of the guitar has a substantially rigid and massive back and sides 32 surrounding an internal cavity 24. These portions of the body are sufficiently solid and rigid to act in a similar manner to the rigid body of a conventional electric guitar.
  • a mounting block 25 is shown rigidly attached to the back of the guitar while the body is also shown as comprising a recess 33 for receipt of the rhythm pickup.
  • An acoustic pre-amplifier 31 is shown mounted in the cavity secured to the rigid side wall thereof.
  • the general internal arrangement of the guitar body can be appreciated from Fig. 3, where the cavity 24 with the mounting block 25 is visible with the lead pickup 13 projecting through an aperture 15 in the table 23.
  • the rhythm pickup 12 is mounted in the aperture 33 in the body to project through an aperture 28 in the front or table 23. It will thus be appreciated that the rhythm pickup 12 projects from a rigidly supported, non-vibrating, portion of the table 23.
  • a preferred material for the table is spruce.
  • the bridge 16 In order to obtain good acoustic properties it is preferred for the bridge 16 to be made fairly massively of solid metal and secured in position by bolts 28 which pass through the table 23 and engage a main piece 27 of bracing secured to the underneath of the table 23 within the cavity 24 as shown in Fig. 4. Radiating outwardly from the main piece 27 of the bracing towards the side wall 32 of the body are arms 26. Also secured to the underside of the table 23 is a transducer 30 which is activated when the guitar is used in its amplified acoustic mode.
  • the electric guitar is of sufficiently rigid construction to operate successfully as a conventional electric guitar and yet it can be simply switched so as to deactivate both the pickups and activate the transducer 30 and then be used to provide an output at least comparable with that obtained from an amplified acoustic guitar. With no electric amplification at all a substantial and adequate volume output can still be obtained simply in a normal acoustic mode using the cavity 24 as a sound box with the vibrating carefully braced table 23 of flexible wood thereabove.
