The Studio Classic is a mini combo version of one of the most popular guitar amps in history: The famous JCM 800!

The original was used by countless rockstars such as Billy Corgan, Jeff Beck, Tom Morello and more spanning many different genres of music proving just how versatile the amp circuit is. It's now available in this 'Studio Classic' format which is switchable between 20w and 5w depending on where 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 tones easily.

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 JCM800 style amp more versatile than ever before.

Stuff About Marshall

Marshall is a legendary British amplifier brand that defined the sound of rock music with its unmistakable power, grit, and presence. Founded by Jim Marshall in London in 1962, the company quickly became synonymous with the roaring tones of the 1960s and 70s, used by icons like Jimi Hendrix, Pete Townshend, and Slash. Known for their iconic “stack” design and warm overdrive, Marshall amps deliver the punchy, dynamic sound that has powered countless stages and recordings. From classic valve amplifiers to modern digital models, Marshall continues to embody the spirit of rock’n’roll—loud, bold, and timeless.

The Important stuff

20W — A 20-watt amp gives you that extra headroom over smaller practice amps while keeping the volume manageable. It’s powerful enough to cut through a band mix in rehearsal or small venues, yet still works well at home when dialled back. Many players like 20 watts for its dynamic response — it can stay clean at moderate levels or break up naturally when pushed. Whether valve or solid-state, 20W amps strike a great balance between tone, power, and practicality.. Guitar Amps and Cabs — Guitar amps and cabs are at the heart of your tone, shaping everything from crisp clean sounds to heavy distortion. Combo amps combine the speaker and amplifier in one portable unit, ideal for rehearsals and small gigs, while separate amp heads and cabinets offer more power and flexibility for stage use. Valve amps deliver classic warmth and dynamic response, while solid-state and modelling amps provide reliable performance and a wide range of tones. Guitar cabinets, from compact 1x12s to full 4×12 stacks, influence projection and character, so matching the right amp and cab setup is key to getting your perfect sound.. Studio. Valve.
