Standard amplifiers, such as the Fender ''tweed''-style amps (e.g., the [[Fender Bassman]]) are often used by traditional rock, blues, and country musicians who wish to create a vintage 1950s-style sound. They are used by electric guitarists, [[pedal steel]] guitar players, and [[blues harmonica]] players. These amps are designed to produce a variety of sounds ranging from a clean, warm sound to a growling, natural overdrive. These amplifiers usually have a sharp treble [[roll-off]] at 5&nbsp;kHz to reduce the extreme high frequencies, and a bass roll-off at 60–100&nbsp;Hz to reduce unwanted boominess. The nickname ''tweed'' refers to the lacquered beige-light brown fabric covering used on these amplifiers.

Combo amplifiers such as the [[Fender Super Reverb]] have powerful [[tube amplifier]]s, 10- or 12-inch speakers, and they often have built-in [[Reverberation|reverb]] and [[Vibrato unit|vibrato]] effects units. These larger combo amplifierss 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. Smaller, lighter guitar amps are also available, which have less powerful amplifier units and as few as one speaker. Smaller guitar amps are easier to transport to gigs and [[sound recording]] sessions. Smaller amps are widely used in small venue shows, because players can obtain the tone they want without having to have an excessively loud volume.  The smallest combo amplifiers, which are mainly used for individual practice and warm-up purposes, may have only a single 8 or 10-inch speaker. Some players use these small combo amplifiers for concert performances, though, because it is easier to create natural overdrive with these lower-powered amplifiers.<!--[[User:Kvng/RTH]]-->
