A wide range of instrument amplifiers is now available, some for general purposes and some designed for specific instruments and even for particular sounds. Traditional guitar amplifiers come up with a clean, warm sound, a sharp treble roll off at 5 kHz or less and bass roll off at 60 to100 Hz, often with built in reverb and tremolo units. Bass amplifiers have extended bass response and tone controls optimized for bass guitars (or more rarely, for upright bass).
Higher end bass amplifiers sometimes include compressor or limited features, which help to keep the amplifier from distorting at high volume levels. Keyboard amplifiers have a very low distortion and extended flat frequency response in both directions. Keyboard amplifiers often have a simple onboard mixer, so that keyboardists can control the tone and level of several keyboards. Acoustic amplifiers are designed specifically to produce a clean, transparent, acoustic sound when used with acoustic instruments with built in transducer pickups and microphones.
Some well known brands of guitar amplifiers
While there are almost innumerable manufacturers of guitar amplifiers, we will be discussing the most important brands that have created history in guitar amplification.
Carvin Corporation
The Carvin Corporation is a musical instrument and equipment manufacturer, located in San Diego, California, well known among guitar players for their guitars. Carvin was founded in 1946 by Lowell Kiesel, and originally manufactured guitar pickups. Carvin Corporation manufactures acoustic and electric guitars, bass guitars and accessories, amplifiers, live studio sound equipments, microphones and lighting gears.
Korg Corporation
Korg Corporation is a Japanese multinational corporation that manufactures electronic musical instruments and guitar tuners. The company is one of the most widely used and respected names in the electronic music world. Founded in 1962 in Japan by Tsutomu Kato and Tadashi Osanai, Korg was originally known as Keio Electronic Laboratories because its fledgling offices were located near the Keio train line in Tokyo and Keio can be formed by combining the first letters of Kato and Osanai. Yamaha Corporation has always been a major partner of Korg, supplying them with circuitry and mechanical parts.
Marshall Amplification
Marshall Amplification is a British company which designs and manufactures electric guitar amplifiers. Marshall Amplifiers are well known and highly popular among guitarists. Marshall Amplifiers were originally built as direct copies of Fender amplifiers, but soon incorporated certain traits which made them more favorable to guitarists seeking a heavier sound. Like most professional level amplifiers, Marshall amplifiers still use valve preamp and power amplifier stages instead of solid state devices. Marshall also manufactures cheaper solid-state or hybrid devices.
Vox
Vox is a musical equipment manufacturer, which is most famous for making the AC30 guitar amplifier and the Vox electric organ. Founded in Great Britain, Vox is now owned by the Japanese electronics firm Korg. In 1959, with sales under pressure from the more powerful Fender Twin and from The Shadows, who requested amplifiers with more power, Vox produced what was essentially a double powered AC15 and named it the AC30.
Roland Corporation
Roland Corporation is a Japanese manufacturer of electronic musical instruments, electronic equipment and software. It was founded by Ikutaro Kakehashi in Osaka on April 18, 1972 with 33 million yen in capital. Some of the recent amplifiers from Roland Corporation are Roland SH 201, Roland Juno G, Roland MV 8800 and Roland V Synth GT.

When you are on the look out for car audio amplifiers, first you got to know how it functions and what is it used for. The purpose of a car audio amplifier is to convert a low level signal from the source unit to a high level signal for driving the loudspeakers. Amplifiers can range in power from 20 watts to over a thousand watts per channel. And their prices too differ from one amplifier to another depending on their features, quality and power. The most popular type of amplifier is the one with 2 to 4 channels model.
If needed, you can even add extra built-in features to car audio amplifiers whenever required. Some of these extra built-in features may include, crossovers, speaker level units, equalizers, and signal processing. While purchasing an amplifier for your car stereo system, there is one thing you need to take into consideration when it comes to dealing with amplifier power ratings. You should see that all power ratings are not created equal. The true measurement for an amplifier power is the RMS rating or the continuous power ratings.
Quality of the car audio amplifier is very important to take into account when buying the amplifier. But the question is how do you know if it is a high quality amplifier? The good indicator of a quality amplifier will be determined by the weight and the size of the amplifier. The heavier the amplifier the better the quality it will produce. But size is not all that matters
Another indication that you can consider is the quality of the car audio amplifier by the size of the fuse used. There are different classes of amplifier, and a quick and easy way to check the true power output is to take the fuse value of the amplifier or the sum of the multiple fuses and multiply it by 6, if it is an A or B class amps, or 10 for class D amps where the efficiency is higher. Though this will not give you an accurate result, but it will be able to indicate if your car audio amplifier is close to the specifications.
If you have a tight budget or lack of space, the most economical thing to do is to opt for a multi-channel amplifier with the required built-in processor and features that you need. This will save you a lot of money and space, which will in turn allow you to add any extra feature to your car audio amplifier. Though there will be difference in quality compared to the outboard processors but this will not be noticeable. Sometime adding too many components can lessen the chance of noise entering into the system.
To sum out in brief, the key features you need to look into before purchasing a car audio amplifier includes, bridgeable, channels, connectors, class, crossovers, distortion, filters, power output, efficiency, speaker level input, stability, separate gain controls, tube amplifier, tri-mode out put, power supply, pre-amp inputs and outputs. But make sure that you always opt for genuine brands through genuine dealers.

Guitar amplifiers are electronic amplifiers designed to be used with electronic musical instruments, such as an electric guitar.
Guitar amplifiers are mainly made in two major forms. The combination (or combo) amplifier has the amplifier head and guitar speakers in a single unit. The amplifier head or amp head contains the electronic circuitry constituting the preamp, built in effects processing, and power amplifier.
In the second form, the amplifier head is detached from the speakers, and joined by cables. The separate amplifier is known as an amplifier head, and is normally located on top of one or more loudspeaker enclosures. This separate amplifier head when placed on top of a guitar speaker enclosure or guitar speaker cabinet forms an amplifier stack or amp stack.
Instrument amplifiers Types
An extensive range of instrument amplifiers can now be used with the electrical guitar. Some are for general purpose and some designed for specific instruments and even for a definite sound. These comprise: Traditional guitar amplifiers which generate a clean, warm sound a sharp treble roll off at 5 kHz or less and bass roll off at 60 to 100 Hz. It has presets with built in reverb and tremolo (vibrato) units.
These types are often used by traditional rock, blues, and country musicians. Chances are that when on higher volume level the sound can get distorted. So to counter higher end bass amplifiers at times include compressor or limiter features, and an XLR DI output to patch the bass signal directly into a mixing board. To keep the bass amplifiers cool they are often provided with external metal heat sinks or fans.
Keyboard amplifiers, have a low distortion rate and also to make things easy for its functioning it has a simple onboard mixer. This assists the keyboardists to control the tone and level of several keyboards.
Acoustic guitar amplifiers are intended solely to produce a clean, transparent, acoustic sound when being used with acoustic instruments with built in transducer pickups and microphones.
In addition to a 1 by 4 inch input jack, some instrument amplifiers bear an additional input jack for inserting microphone. This is known easily as it will use a three pin XLR connector. Conversely, phantom power, which is not a necessary for lower end amplifiers, is often provided with the high end versions, so that musicians can use condenser microphones.
Vacuum tube guitar amplifier circuit is rather uncomplicated. Two triodes are used in the preamplifier section for obtaining a high signal level to implement any tone controls and drive the following sections. Two more triodes split the phase of the signal and drive the final pentode or beam tetrode (kinkless tetrodes) tubes of the push pull power amplifier stage.
Solid state guitar amplifiers commonly have the quickest response time, even more so than modeling amps. Tubes tend to create warm overdrive sounds instead of cutting the peaked signal off. They more or less pull the peaked audio information back (like natural compression) which creates a fuzzy overdrive sound.
Modeling guitar amplifiers are used to simulate sounds of well known cabinets, guitar amps, and effects. Digital processing is done to obtain this, although there are prevalence analog modeling amps as well, like the Tech 21 Sansamp. Modeling amps characteristically output a wide range of tones and effects, and offers cabinet simulation, which aids the recording without a microphone.

An amplifier is a gadget that transfers an increasing sound of an instrument. Amplifiers are widely used in radios, television sets, microcomputers, guitars and other instruments of music. There are different kinds of amplifiers.
An amplifier is a gadget that transfers the increasing sound of an instrument. Amplifiers are widely used in radios, television sets, microcomputers, guitars and other instruments of music. There are many types of amplifiers which include the following: electronic, power vacuum or valve tube, video, music and many more.
Moreover, amplifiers have certain features that are important to consider. These features are gain, bandwidth, efficiency, linearity, noise, output dynamic range, slew rate, rise time, settling time and ringing, overshoot and lastly the stability factor. Nowadays, amplifiers normally refer to an ‘electronic amplifier’ that has an audio. Amplifiers also have an input frequency known as the ‘transfer function’. Amplifiers also have magnitudes of the transfer function that are called ‘gain’. An amplifier is a device that highlights the sound of any instrument.
Listed below are the features of an amplifier:
? Gain: The gain of an amplifier is the ratio of the output to the input power and is basically measured by the volume.
? Bandwidth: Bandwidths give the amplifier a ’satisfactory performance’. This feature can also be defined as “the dissimilarity between the lower and upper half power points”. The half power points are located where the power goes down by half its peak value.
? Efficiency: This amplifier feature is measured by how much input power is usefully applied to the amplifier. The limit of an ordinary amplifier is that the amplifier has up to 50 percent efficiency. Class A amplifiers are useless. This is because the efficiency of this kind of gadget ranges from 20 up to 30 percent with a maximum percentage of 45. Class B amplifiers have extremely high efficiency.
? Noise: The noise is measured by the amount of noise the amplifier had launched. The noise is also measured by its volume and also known as the “peak output power” that is created by the amplifier.
? Output dynamic range: The output dynamic range that is frequently specified in amplifiers is between the minimum and prime functional output levels. The lowest functional level is limited by the output noise while the prime is limited by distortion.
? Slew rate: The rate modifies the output variable. Slew rates are usually quoted in volts per second. A lot of amplifiers are only limited to its slew rate. Thus, they are typically the impedance of a drive current having to overcome the capacitive effects. The slew rate may limit the full power of the bandwidth.
? Rise time: The rise time of an amplifier is the time taken for the output to change from 20 percent up to 90 percent on its final level by driving a step input.
? Settling time and ringing: The settling time and ringing is the time taken for the output to settle to a certain percentage of the final value. This is generally precise for oscilloscope vertical amplifiers and has a high accuracy measurement system. Ringing refers to an output that cycle its final value while its final value had been delayed.
? Overshoot: It is the amount of output exceeded to its final and steady-state value.
? Stability factor: Stability factors are a main concern in RF and microwave amplifiers. The stability degree of an amplifier can be regarded by a so-called stability factor.
Listed below are several types of Amplifiers.
? Electronic amplifier: This type of amplifier is a gadget that is normally used in radios, televisions, guitars, microcomputers and other instruments. An electronic amplifier may be considered as a device used for modulating the output of a power supply.
? Power amplifier: This particular kind of amplifier is used in taking a signal from a source gadget and making it appropriate for a powerful loudspeaker. The purpose of this power amplifier is to take a weak signal and make it a strong one, which should be enough to drive a powerful speaker. The units of power amplifiers are known as watts. Power amplifiers also have a power rating. The power rating is present in various types of amplifiers. Power amplifiers are the ones that typically need the most attention towards the power.
? Vacuum Amplifier: This type of amplifier is also called a valve tube amplifier. It is a gadget that is used to create an electrical signal by controlling the function of electrons in a low-pressure space. A vacuum or valve amplifier is much more cost efficient in a high power application such as ‘radar’ counter measures equipment or communication equipment. A vacuum or valve tube amplifier also has an application of pre-dated electronics. Electronics is determined as a mechanical computer like slide that rules to the peak of obsolescence.
? Operational amplifier: operational amplifiers are also called “Op-amps”. This kind of amplifier has a solid state of integrated circuit amplifiers that is used in order to control any outside feedback. Operational amplifiers must contain a high-gain electronic voltage amplifier with a degree of difference in its inputs and a normally single output. Usually, the output of this kind of amplifier is controlled by a negative feedback that has a large verified degree of its output voltage. Op-amps have the most widely used electronic gadget. This kind of amplifier is also the most used by consumers. Operational amplifiers are used as an industrial and scientific gadget.
