Marshall Amplification Company Profile

Why Do Marshall Amps Sound So Good - Marshall Logo

Marshall Amplification is a British company renowned for manufacturing music amplifiers and speaker cabinets.

The company was founded by Jim Marshall in London, England, in 1962. Jim Marshall was a drummer and drum teacher who used his musical background and the feedback of the musicians he knew to start creating equipment that catered to the needs of these performers. The first-ever Marshall amplifier, affectionately known as “Number One,” was crafted in a small shop in Hanwell.

Marshall has produced some famous amplifiers over the years, including the Bluesbreaker, JMP, JCM800, JCM900, and DSL series, each with its unique traits and enhancements. Furthermore, Marshall has expanded its horizons by crafting solid-state amps and digital modeling amps, like the “Code” series, to cater to a diverse spectrum of musicians and requirements.

Even though its founder, Jim Marshall, passed away in 2012, Marshall Amplification is still dedicated to building upon its prestigious heritage. It continues to be an influential player in defining the sound of music genres such as Rock, Metal, and Blues. Respected by musicians, technicians, and music aficionados the world over, Marshall remains a revered name in the industry.

Marshall Design Specifications

The design and build quality of Marshall amps are unparalleled. Their sturdy cabinet construction, usually composed of birch plywood, has proven to withstand the test of time and the rigors of touring. These amps also have their classic black and gold color scheme that has become a staple on stages worldwide.

Why Marshall Amps Have A Class AB Circuit Design

Part of what gives a Marshall amp its sound and performance is its Class AB circuit design, which allows for more efficient power output and helps maintain that iconic tone while pushing volume levels.

A Class AB amplifier is a type of power amp that combines the best qualities of Class A and Class B amplifiers, hence the name AB. These amps don’t use the bulk of their audio power until it is required.

So, Class AB amplifiers can provide both good efficiency (less heat, less power consumption) and good signal fidelity with a better signal-to-noise ratio than Class A amps, which is why this design is so commonly used, particularly in music amplification.

Does Marshall Make Class A Amplifiers?

The answer is no. No Marshall amplifiers are “truly” Class A in the strictest electrical engineering sense.

Class A amplifiers are defined as amplifiers in which the output signal is always present, regardless of the input signal. This means that the amplifier is constantly consuming power, even when there is no sound being played. Although they can have smoother distortion characteristics when overdriven, Class A amps are more inefficient and difficult to cool.

Models like the Marshall the 1974X and the hand-wired series Marshall 2061X are often referred to as Class A amplifiers. However, if we look at them in the strictest sense from an electrical engineering perspective, they are actually not Class A. Their “Class A” designation is due to marketing reasons or for their tonal qualities that resemble those of Class A amplifiers, including a certain warmth and responsiveness.

The closest Marshall to a Class A amplifier is the Marshall Class 5. The Class 5 is a 5-watt combo amp that uses a single EL84 tube in the power stage. This gives the amplifier a classic Class A sound, but it is still more efficient than a true Class A amplifier.

Why Marshall Amps Are So Highly Sought After

Here are the most important ingredients that make up the “Marshall Secret Sauce.”

Iconic “British Sound”

Marshall amps are famed for their warm, crunchy tone with a focused midrange, providing a distinctive audio quality that helped define the sound of Rock and Roll, Metal, and Blues. The distinctive sound of Marshall amps primarily boils down to their components and circuitry, such as EL34 and EL84 power tubes.

American amps are primarily known for their shimmering cleans and more scooped mids.

Pleasing Harmonic Distortion

These amps are also popular for their harmonic distortion. As the gain on a Marshall amp increases, it creates a musically appealing break-up, offering a more dimensional crunchy and thick tone, also known as the “Marshall growl.”

Class AB Circuitry And High-Quality Components

As discussed above, AB circuitry allows for more efficient power output and helps maintain the amp’s iconic tone at higher volume levels. Marshall uses only the highest quality components.


Marshall is a brand steeped in Rock history, offering an appealing heritage aspect for musicians. Owning and playing a Marshall is like being part of a rich music tradition and a right of passage for any Rock or Metal player.

I still remember the feeling of musical exhilaration when I got my first Marshall half-stack. I played it all day and only got two hours of sleep that night! I must have played every guitar riff and solo I knew!


Many renowned guitar players have used and endorsed Marshall amps, which only added to a Marshall’s desirability and appeal. Who wouldn’t want to have the amp your favorite guitarist played, even if you didn’t have a wall of them?

Hand Wired Marshall Amps – The “Real Magic”

Marshall began moving away from point-to-point, and hand-wired construction to printed circuit boards (PCBs) in the late 1970s, primarily for cost and efficiency reasons.

The famous Marshall JCM800 amp, which began in 1981, was predominantly PCB-based.

While some purists believe that hand-wiring results in a better tone, the transition to PCBs has allowed Marshall (and other amp manufacturers) to produce their amps more consistently, efficiently, and at a lower cost. This transition doesn’t necessarily denote a decline in quality. Some PCB-based Marshall models, like the JCM800, are considered classics and highly sought after.

In response to market demand for hand-wired amps, Marshall reintroduced versions of several of their classic models in the 2000s. These models are part of the Marshall Handwired Series, and they allow musicians to own a brand-new amplifier built using traditional hand-wired techniques.

More attention to detail during manufacturing can mean enhanced reliability and less time in the shop being serviced. True point-to-point wiring may be easier and less time-intensive to service than a printed circuit board design.

My Take On Marshall Hand Wired Amps

I’ve played through a variety of hand-wired amps and heard others onstage over the years, both new and vintage models, including:

  • Fender ’64 Custom Deluxe Reverb
  • Marshall 1974X Tube Combo
  • Vox AC15HW1X
  • Matchless Laurel Canyon 112r
  • Carr Super Bee

I like that hand-wiring the circuitry can allow you to use larger electronic components, like resistors and capacitors, which can give you a better tone.

Hand-wired amps are not necessarily more road-worthy than PCB or Hybrid amps. It depends on the design, materials, and manufacturing process.

They are more dimensional sounding and give my playing a more touch-sensitive feeling, which allows me to emphasize very subtle variations in my technique.

So, although hand-wired amps can be pricey and typically have fewer bells and whistles, I tend to favor their tone and dynamics, with notable exceptions, but ultimately it’s your call!

All Marshall Amps Sound And Perform Different!

Beware of an issue in this review

The sound and playability of each Marshall amp model will vary according to a number of factors.

Playing Style And Guitar

Your playing style is one of the key determinants of how your guitar will sound when you plug it into an amplifier, depending on how you fret and pick the strings. This is one of the main reasons you should play through an amp using your guitar to hear its true tone and capabilities.

Guitars with various shapes, tonewoods, and pickups can significantly change the sound of an amplifier. For example, humbucking pickups will push an amp into overdrive or distortion easier than single-coil pickups.

Amplifier Type

Tube, solid-state, and digital modeling amps can each provide different sounds. Tube amplifiers are known for their warm, dynamic tones and natural distortion. Solid-state amplifiers are recognized for their clear tones, reliability, and durability. Digital modeling amplifiers can emulate the tones of various tube and solid-state amps.

Wattage And Headroom

Higher-wattage amplifiers provide more headroom, which is the capacity to increase the volume before the onset of distortion. This is crucial for playing clean tones at louder volumes. On the other hand, lower wattage amps break up and distort at lower volumes, which is desirable for some styles.

Class of Operation

Guitar amps operate in different classes, mainly Class A or Class AB, which affects the tone and response. Class A amps generally offer a warmer tone and smoother breakup, while Class AB amps are more efficient and louder. All Marshall amps are technically Class AB, but some models are designed to sound and perform like a Class A amp.

Number Of Channels

Many amps offer multiple channels, each with its own gain and EQ settings, allowing quick switches between sounds. It’s essential to check out the features and sounds available on each channel.

Tone Control And EQ

Amplifiers offer various degrees of tone control, from simple bass and treble knobs to multi-band equalizers. These controls allow players to sculpt their sound by boosting or cutting specific frequency ranges.

Volume And Gain Controls

The interaction between the amp’s volume and gain controls allows players to balance the level of clean and distorted tones. Some amplifiers don’t have an adjustable gain control.

Onboard Effects

Some Marshall amplifiers come with built-in effects like reverb and tremolo. Modeling amps, like the Marshall Code Series, offer delay, chorus, and a range of amplifier models which can significantly modify the sound.

Speaker Size And Configuration

The size and number of speakers in an amplifier affect its sound projection and frequency response. Larger speakers generally produce more bass frequencies, while smaller speakers excel at higher frequencies.

Cabinet Design

The design of the amplifier cabinet (open-back vs. closed-back) can also affect the sound, particularly its directionality and bass response.

Amplifier Age

Marshall has gone through many amplifier designs and configurations over the years. Vintage and Hand-Wired Series amplifiers can sound and perform differently than more modern designs. Most of the coveted Marshall amps are examples from the initial designs, like the Plexi and Super Lead vintage amps.

Are Marshall Amplifiers Legit?

My Guitar Lair - A scale trying to balance a guitar player on one side and a stack of coins on the other side.
