The acoustic bass guitar (sometimes shortened to acoustic bass or initialized ABG) is a bass instrument with a hollow wooden body similar to, though usually larger than a steel-string acoustic guitar.
 Like the traditional electric bass guitar and the double bass, the acoustic bass guitar commonly has four strings, which are normally tuned E-A-D-G, an octave below the lowest four strings of the 6-string guitar, which is the same tuning pitch as an electric bass guitar.
heavy metal me is a DVD release by Japanese band Boris.
 It consists of various live material, video material, and "heavy metal me", a short film which is subtitled in both Japanese and English.
 The titular short film is actually a series of chapters on the disc which play in a random order every time the user hits play (though the chapters for each language remain together).
 Filmed primarily in black and white, the piece is deliberately low quality and aged, with guitarist Wata playing the lead; most chapters feature analog hiss and white noise for audio tracks, though some are totally silent, and others contain acoustic guitar plucks atop the hiss.
 The "a bao a qu" music video is based on the 7" version of the song with both sides crossfaded together into a 9-minute full length version; its video consists of extremely wide and narrow shots with low quality lighting, following several characters as they walk the streets, smoke, and reflect or contemplate.
 "the evil one which sobs" layers the titular song with its ambient counterpart "Interference Demon" from "Dronevil", but starts the former several minutes later than the coupling of the CDs would play, and fades out just at the end of the loud drone (thus removing the acoustic guitar coda of CD2); the video consists solely of shots from what appear to be underneath layers of moving webbing.
 Lastly, there are live versions of the songs "feedbacker", recorded 2003-11-1 at Shinjuku Liquid Room, and "flood", recorded 2001-5-3 at Koenji 20,000v. "staff credit" contains acoustic guitar plucks while the credits roll.
 The DVD has no "play all" option and each track must be selected individually from the main menu.
A flat top guitar is a type of guitar body model which has a flat top (as opposed to archtop).
 The term "flat top" is usually used to refer to the most popular type of steel-string acoustic guitars; however, electric guitars such as the Fender Stratocaster, the Fender Telecaster and the Gibson Les Paul Junior and Special can be described as "flat top".
BR549 (originally spelled BR5-49) was an American country music band.
 Founded in 1993, the band originally comprised Gary Bennett (lead and background vocals, acoustic guitar), Don Herron (steel guitar, Dobro, fiddle, mandolin, acoustic guitar), "Smilin'" Jay McDowell (upright bass), Chuck Mead (lead and background vocals, acoustic guitar, electric guitar), and "Hawk" Shaw Wilson (drums, background vocals).
 Bennett and McDowell left the band in 2001, with Chris Scruggs and Geoff Firebaugh respectively replacing them.
 Both Firebaugh and Scruggs later left the band as well; Mark Miller has become the band's third bassist.
 The name of the band is an homage to comedian Junior Samples.
B-Bender is a guitar accessory that enables a player to mechanically bend the B-string up a whole tone (two frets) to C-sharp.
 There are several different designs, but all use levers or pulleys inside or outside the guitar body that are activated by a pull or push of the guitar neck, body, or bridge.
 The resulting tone sounds much like a pedal steel guitar and contributes a "country" feeling.
 Originally designed for the Fender Telecaster, B-Benders are now available to fit many solid body electric guitars, and even acoustic guitars.
C.F. Martin & Company is an American guitar manufacturer established in 1833 by Christian Frederick Martin.
 Martin is highly regarded for its steel-string guitars and is a leading manufacturer of flat top guitars. Martin instruments can sell for thousands of dollars, and vintage instruments occasionally command six-figure prices.
 The company has also made mandolins as well as several models of electric guitars and electric basses, although none of these other instruments are currently in production.
The steel-string acoustic guitar is a modern form of guitar that descends from the classical guitar, but is strung with steel strings for a brighter, louder sound.
 It is often referred to simply as an acoustic guitar, though the nylon-strung classical guitar is sometimes also called an acoustic guitar.
The classical guitar (also known as concert guitar, classical acoustic, nylon-string guitar, or Spanish guitar) is the member of the guitar family used in classical music.
 It is an acoustical wooden guitar with strings made of nylon, rather than the metal strings used in acoustic and electric guitars.
 The traditional classical guitar has twelve frets clear of the body and is held on the left leg, so that the hand that plucks or strums the strings does so near the back of the soundhole (this is called the classical position).
 The modern steel string guitar, on the other hand, usually has fourteen frets clear of the body (see Dreadnought) and is commonly played off the hip.
An acoustic-electric guitar (also called an electro-acoustic guitar) is an acoustic guitar fitted with a magnetic pickup, a piezoelectric pickup or a microphone.
 In electric-acoustic nylon string guitars, piezoelectric pickups and microphones are always used because magnetic pickups are not capable of picking up vibrations of non-magnetic materials.
 The design is distinct from a semi-acoustic guitar, which is an electric guitar but with the addition of sound chambers within the guitar body.
 Usually, acoustic-electric guitars are fitted with piezoelectric pickups, and hence require a preamplifier incorporated into the guitar body to amplify the signal before it travels to the main guitar amplifier.
 These preamps may also come with tone controls of varying types, but usually equalizers with up to six frequency bands are used.
 They are also referred to as a "plug-in acoustic guitar", due to their ability to simply "plug in" to a speaker system without the need for microphones.
The "Dreadnought" is a type of acoustic guitar body developed by guitar manufacturer C.F. Martin & Company.
 The Dreadnought style, since copied by other guitar manufacturers, has become the most common of all styles of guitar bodies.

Question: The "Dreadnought" is a type of acoustic guitar body developed by a manufacturer established in this year?
