The Studio Vintage is a mini version of one of the most popular guitar amps in history and the amp that has put Marshall on the map forever: The Plexi!

The original Plexi amps were used by countless guitar heroes such as Jimi Hendrix, Eddie Van Halen, Jimmy Page, John Frusciante and many more!

It's now available in this 'Studio' format which is switchable between 20w and 5w depending on how you're using it. The lower wattage (compared to the original 100w head) allows you to drive the tubes at lower volumes and capture those classic hot blues tones easily.

Fat blues tones

There's a reason that so many famous guitarists love the sound of a Plexi and when you plug into one and crank it you'll see why. They're clear and crisp with plenty of mid-range for you to cut through the mix but with oodles of sustain. Your fiery solos will be singing for days.

DI Output & Effects Loop

It's also got a DI output which allows you to plug it directly into your recording interface and capture the sound of the amp with an emulated mic'd up cab sound. This is what makes it so versatile and useful to have in the studio – you don't even need to mic it up! 

It's also got an effects loop so that you can choose where the preamp saturation is in your signal chain, making this Plexi-style amp more versatile than ever before! 

Here's what Marshall say about the Studio Classic 20

20W

20W refers to the power rating of an amplifier, indicating it can deliver 20 watts of output. A 20-watt amp is ideal for practice, small gigs, and studio recording, offering a good balance between volume and portability. These amps can provide rich tone and natural overdrive at manageable volumes, making them popular with guitarists who want quality sound without excessive loudness.

Amp

An amp, short for amplifier, is a crucial piece of equipment that boosts the signal from your guitar or other instruments, allowing you to control volume and shape your tone. Guitar amps come in various styles, including valve (tube), solid-state, and digital modelling, each offering unique sound characteristics. Whether you’re practicing at home, recording in the studio, or playing live, the right amp can make all the difference in achieving your desired sound—from clean and crisp to rich overdrive and distortion.

Guitar Amps and Cabs

Guitar amps and cabs are just as crucial to a guitarist’s tone as the guitar itself. Amplifiers shape the sound—whether it’s clean and warm, crunchy and bluesy, or full-on distortion for rock and metal. They come in two main types: combo amps, which include both the amp and speaker in one unit, and amp heads, which are paired with separate cabinets (cabs) to project the sound.

Cabs come in various sizes, like 1×12, 2×12, or the mighty 4×12, each delivering different tone and feel. Speakers, cabinet wood, and even open vs closed backs all influence the sound. Matching the right amp and cab gives players control over their dynamics, tone, and presence—whether you’re playing in your bedroom, a studio, or on a festival stage.

Head Amplifier

A head is the amplifier unit of a guitar rig that contains the electronics responsible for shaping and boosting your guitar’s signal. Unlike combo amps, a head does not include built-in speakers and needs to be connected to a separate speaker cabinet. This setup offers greater flexibility, allowing players to mix and match different heads and cabinets to tailor their tone and volume. Heads come in various types, including valve (tube), solid-state, and modelling, catering to a wide range of sounds and playing styles.

Studio

valve

Valve, also known as tube, refers to a type of amplifier technology that uses vacuum tubes to amplify the guitar signal. Valve amps are renowned for their warm, rich tone, natural compression, and smooth distortion when driven hard. Many players prefer valve amps because of their dynamic response and organic sound character. Although they require more maintenance and can be heavier than solid-state amps, valve amplifiers remain a favourite choice for professional musicians seeking classic tones and expressive performance.

Vintage

A vintage guitar is a guitar that is considered to be of significant age, typically over 30 years old, and often possesses historical, cultural, or collector’s value. Vintage guitars are highly sought after by collectors, musicians, and enthusiasts for their craftsmanship, tone, playability, and historical significance.

Vintage guitars can come from various eras, each with its own unique characteristics and desirability.

Vintage guitars often exhibit signs of wear and aging, which can add to their character and authenticity. However, originality, condition, and provenance are crucial factors that determine the value of a vintage guitar. Well-maintained and all-original vintage guitars with documented history and provenance tend to command higher prices on the collector’s market.

While vintage guitars can be valuable investments, they are also cherished for their playability and the unique sonic characteristics they offer. Many musicians prefer vintage instruments for their mojo, vibe, and connection to music history.
