An instrument amplifier is used with musical instruments such as an electric guitaran electric basselectric organsynthesizers and drum machine to convert the signal from the pickup with guitars and other string instruments and some keyboards or other sound source e.
Combination "combo" amplifiers include a preamplifiera power amplifier, tone controls, and one or more speakers in a cabineta housing or box usually made of hardwood, plywood or particleboard or, less commonly, moulded plastic. Instrument amplifiers for some instruments are also available without an internal speaker; these amplifiers, called headsmust plug into one or more external speaker cabinets.
Some amplifiers are designed for specific styles of music, such as the "traditional"-style "tweed" guitar amplifiers, such as MP3) Fender Bassman used by blues and country music musicians, and the Marshall amplifiers used by hard rock and heavy metal bands.
Unlike home "hi-fi" amplifiers or public address systemswhich are designed to accurately reproduce the source sound signals with as little harmonic distortion as possible and without changing the tone or equalization at least not unless the hi-fi owner adjusts it themselves with a graphic equalizerinstrument amplifiers are often designed to add additional tonal coloration to the original signal, emphasize or de-emphasize certain frequencies most electric guitar amps roll off the very high frequenciesand, in the case of guitar amplifiers designed for electric guitar or Hammond organoffer the capability to intentionally add some degree of " overdrive " or distortion to the tone.
The two exceptions are keyboard amplifiers designed for use with digital pianos and synthesizers and "acoustic" instrument amplifiers for use with acoustic guitar or fiddle in a folk music setting, which typically aim for a relatively flat frequency response i. A guitar amplifier amplifies the electrical signal of an electric guitar or, less commonly, with acoustic amplifiers, an acoustic guitar so that it can drive a loudspeaker at sufficient volume for the performer and audience to hear.
Most guitar amplifiers can also modify the instrument's with controls that emphasize or de-emphasize certain frequencies and add electronic effects. String vibrations are sensed by a suitable microphone or pickupdepending on the type of guitar. For electric guitars, strings are almost always made of metal, and the pickup works by electro-magnetic induction these are called magnetic pickups; they are the most widely used type of pickup on electric guitars.
Acoustic guitars do not usually have a built-in pickup or microphone, at least with entry-level and beginner instruments. Some acoustic guitars have a small condenser microphone mounted inside the body, which designed Amplified Resophonic Guitar - Richard Kamerman - Trace Being (File convert acoustic vibrations into an electrical signal, but usually they do so from direct contact with the strings replacing the guitar's bridge or with the guitar's body, rather than having a membrane like general-purpose microphones.
Acoustic guitars may also use a piezoelectric pickup, which converts the vibrations of the instrument into an electronic signal. More rarely, a magnetic pickup may be mounted in the sound hole of an acoustic guitar; while magnetic pickups do not have the same acoustic tone that microphones and piezo pickups can produce, magnetic pickups are more resistant to acoustic feedback. Standard amplifiers, such as the Fender "tweed"-style amps e.
They are used by electric guitarists, pedal steel guitar players, and blues harmonica "harp" players. Combo amplifiers such as the Fender Super Reverb have powerful, loud tube amplifiersfour 10" speakers, and they often have built-in reverb and " vibrato " effects units.
Smaller guitar amps are also available, which have fewer speakers some have only one speaker and lighter, less powerful amplifier units. Smaller guitar amps are easier to transport to gigs and sound recording sessions.
Smaller amps are widely used in small venue shows nightclubs and in recordings, because players can obtain the tone they want without having to have an excessively loud volume. One of the challenge with the large, powerful 4x10 Fender Bassman-type amps is that to get the tone a player wants, they have to turn up the amp to a loud volume, Amplified Resophonic Guitar - Richard Kamerman - Trace Being (File. These amps are designed to produce a variety of sounds ranging from a clean, warm sound when used in country and soft rock to a growling, natural overdrive, when the volume is set near its maximum, when used for bluesrockabillypsychobillyand roots rock.
The nickname "tweed" refers to the lacquered beige-light brown fabric covering used on these amplifiers. The smallest "combo" amplifiers, which are mainly used for individual practice and warm-up purposes, may have only a single 8" or 10" speaker. Some harmonica players use these small combo amplifiers for concert performances, though, because it is easier to create natural overdrive with these lower-powered amplifiers.
Larger combo amplifiers, with one 12 inch speaker or two or four 10 or 12 inch speakers are used for club performances and larger venues. For large concert venues such as stadiums, performers may also use an amplifier "head" with several separate speaker cabinets which usually contain two or four 12" speakers. Electric guitar amplifiers designed for heavy metal are used to add an aggressive "drive", intensity, and "edge" to the guitar sound with distortion effects, preamplification boost controls sometimes with multiple stages of preampsand tone filters.
While many of the most expensive, high-end models use s-style tube amplifiers even in the sthere are also many models that use transistor amplifiers, or a mixture of the two technologies i. Amplifiers of this type, such as Marshall amplifiersare used in a range of the louder, heavier genres of rock, including hard rock, heavy metaland hardcore punk.
This type of amplifier is available in a range of formats, ranging from small, self contained combo amplifiers for rehearsal and warm-ups to heavy "heads" that are used with separate speaker cabinets—colloquially referred to as a "stack. In the late s and early s, public address systems at rock concerts were used mainly for the vocals. As a result, to get a loud electric guitar sound, early heavy metal and rock-blues bands often used "stacks" of 4x12" Marshall speaker cabinets on the stage.
In the s, metal bands such as Slayer and Yngwie Malmsteen also used "walls" of over 20 Marshall cabinets. However, by the s and s, most of the sound at live Amplified Resophonic Guitar - Richard Kamerman - Trace Being (File was produced by the sound reinforcement system rather than the onstage guitar amplifiers, so most of these cabinets were not connected to an amplifier.
Instead, walls of speaker cabinets were used for aesthetic reasons. Amplifiers for harder, heavier genres often use valve amplifiers known as "tube amplifiers" in North America also. Valve amplifiers are perceived by musicians and fans to have a "warmer" tone than those of transistor amps, particularly when overdriven turned up to the level that the amplifier starts to clip or shear off the wave forms.
Instead of abruptly clipping off the signal at cut-off and saturation levels, the signal is rounded off more smoothly.
Vacuum tubes also exhibit different harmonic effects than transistors. In contrast to the "tweed"-style amplifiers, which use speakers in an open-backed cabinet, companies such as Marshall tend to use 12" speakers in a closed-back cabinet.
These amplifiers usually allow users to switch between "clean" and distorted tones or a rhythm guitar -style "crunch" tone and a sustained "lead" tone with a foot-operated switch. Bass amplifiers are designed for bass guitars or more rarely, for upright bass. They differ from amplifiers for the electric guitar in several respects, with extended low-frequency response, and tone controls optimised for the needs of bass players.
Higher-cost bass amplifiers may include built-in bass effects units, such as audio compressor or limiter features, to avoid unwanted distorting at high volume levels and potential damage to speakers; equalizers; and bass overdrive. Speaker cabinets designed for bass usually use larger loudspeakers or more loudspeakers, such as four ten-inch speakers than MP3) cabinets used for other instruments, so that they can move the larger amounts of air needed to reproduce low frequencies.
Bass players have to use more powerful amplifiers than the electric guitarists, because deep bass frequencies take more power to amplify [ citation needed ]. While the largest speakers commonly used for regular electric guitar have twelve-inch cones, electric bass speaker cabinets often use 15" speakers. Bass players who play styles of music that require an extended low-range response, such as death metalsometimes use speaker cabinets with 18" speakers or add a large subwoofer cabinet to their rig.
Speakers for bass instrument amplification tend to be heavier-duty than those for regular electric guitar, and the speaker cabinets are typically more rigidly constructed and heavily braced, to prevent unwanted buzzes and rattles. Bass cabinets often include bass reflex ports, vents or openings in the cabinet, which improve the bass response and low-end, especially at high volumes. A keyboard amplifierused for the stage pianosynthesizerclonewheel organs and similar instruments, is distinct from other types of amplification systems due to the particular challenges associated with keyboards; namely, to provide solid low-frequency sound reproduction and crisp high-frequency sound reproduction.
It is typically a combination amplifier that contains a two, three, or four-channel mixera pre-amplifier for each channel, equalization controls, a power amplifiera speakerand a hornall in a single cabinet.
Notable exceptions include keyboard amplifiers for specific keyboard types. The vintage Leslie speaker cabinet and modern recreations, which are generally used for Hammond organsuse a tube amplifier that is often turned up to add a warm, "growling" overdrive. Some electric pianos have built-in amplifiers and speakers, in addition to outputs for external amplification.
These amplifiers are intended for acoustic instruments such as violin "fiddle"mandolinand acoustic guitar —especially for the way musicians play these instruments in quieter genres such as folk and bluegrass.
There is no need to add any reverb to the mix - Our guitars have plenty of natural reverb!!! Photo by Liz Aiken - copyright Visit Liz's excellent website to see more photos of blues artist at lizaiken. There are a number of internal resonator pick-ups on the market. An internal pick-up is ideal for this application and it makes set-up much easier.
The designs come in passive and active versions. Each has advantages and disadvantages. The passive systems often need a pre-amp if plugged into a balanced input on a mixing desk although most have enough output to go direct into a guitar amp input.
The active systems place a battery inside the guitar plus electronics to balance the output, so eventually the guitar must be opened up for these to be changed. We lean towards the simplicity of the passive systems and an outboard pre-amp if required for the specific application. A surface mounted magnetic pick-up gives a very unique and recognisable tone. Many famous slide players have used this option for both the grittier tone they could achieve and the feedback resistant power to get over electric guitars and drum kits.
I have not listened to enough amplified blues harp to know what the best Tone sounds like. I would like to have a contest, providing Richard's dry WAV file so you can try to make a re-amped MP3 that sounds better than mine. But I need to set up something like an derbattmogegefilykornorolsoftcat.xyzinfo area, because my site has limited download capacity.

Updated: July Apr 21, · To produce an amplified sound that will approximate that of an acoustic guitar, you need wide-range speakers with very low distortion--just the opposite of what most electric guitarists would choose. These speakers must be more like studio monitors in that you’ll need fairly flat response, from about 50Hz on up to as high as 15 or 20kHz. A top-notch acoustic guitar amp will amplify the natural tone of your acoustic guitar without noticeably altering it. If you want a louder sound, you need one of these. Even if you typically play at home or in the studio, you'll still greatly benefit from an amp, and many offer built-in . I did consider using a stereo mm jack from the MP3, then down to a shorted (combined positives) mono mm (1/4"), jack patch lead and using it the way that you have suggested, but it has been suggested elsewhere, that just combining the 2 stereo positives, could lead to problems with the MP3 player:(The amp itself does not switch off the two internal speakers, when the supplied.
