Amplifiers

By: shaheen
 

If you love playing the guitar, you also love hearing them at concerts and other events. One thing is for certain, if you are going to play for an audience, you need an amplifier that will deliver quality sounds.While building guitar amplifier kits is an excellent way to get a wonderful sounding amplifier at a greatly discounted price, there is a catch. Most kits require an intermediate to advanced understanding of electronics to correctly and safely complete themThe good folks at Tube Depot sell complete kits modeled after some of the most popular amplifiers ever made: Fender Tweed, Fender Blackface Deluxe, Fender Bassman and Marshall JTM 45. Kits for high quality Hi-Fi systems are also available.
Guitar amplifiers are electronic amplifiers specially designed to be used with electronic musical instruments.
They are mainly made in two major forms. The combination (or combo) amplifier has the amplifier head and guitar speakers in a single unit. The contains the electronic circuitry constituting the preamp, built in effects processing, and power amplifier.
In the second form, the head is detached from the speakers, and joined by cables. The separate head is normally located on top of one or more loudspeaker enclosures. This separate head when placed on top of a speaker enclosure or cabinet forms an amplifier stack or amp stack.
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.
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.
