    Product Description

    The Marshall Origin range has been created for those Marshall purists after a single-channel amp that captures all of the original vibe and mojo of the original Marshall amps from the 50s and 60s but with modern features and organic clean and crunch sounds.

    You can switch between wattages to increase or decrease your headroom. This essentially means how loud you need to turn it up before it distorts and you get that stunning British overdrive tone. The lower the wattage, the lower the volume needed to get it to crunch. But for bigger venues, you’ll want more headroom so that your tone sounds more ‘open’ and less compressed.

    The lower wattages are perfect for home use and studio recording and the higher wattages are more suited to taking pedals really well. This enables them to create a sonic platform for the pedal (especially overdrive and fuzz) to work its magic on.

    Classic Marshall

    The Origin amps use 3x ECC83 preamp valves and 2x EL34 power valves to generate those classic British tones. Gritty and powerful with a strong mid-range presence, these amps can easily cut through the mix for guitar solos or hold down the rhythm section.

    Effects Loop & Emulated Output             

    The Origin amps have got an effects loop for you to run your delays, reverbs and mods into. This is especially handy if you use the drive from the amp. And it’s got an emulated output for silent recording or for running a direct sound to the front of house PA system when playing a gig.

    Tilt Control – 2 Preamp Voicings

    The Origin amps have got 2x preamps voicings and you can blend between the 2 using the ‘Tilt’ control knob next to the EQ section. The two voicings are Normal and High Treble which you can tailor depending on the type of guitar you’re using. A dark sounding guitar with humbuckers might want more treble for example.

    Mr Mick Di Trana24th Sep 2021

    If you are a fan of vintage tones, then this amp will impress. Highly affordable and though it is not made in the UK, it is built with the same quality components as the Studio range. Tone wise it isn't the same as my SV20H, but stick a pedal in front and voila!

    The Origin 20W Amp Head condenses classic Marshall tones in a home, studio and small gig-sized package that sounds just awesome through my Marshall cab.

    Mr Jaka Jarc19th Feb 2020

    My first Marshall, having mostly used fenders, Victory v40, Egnater rebel 30, Laney Lionheart. What the Origin 20 has is a very large thick sound, and that Marshall squelch with pick attack. It is also gorgeous and very loud! The Amp itself drives only when both the preamp and power amp valves are pushed. However the clean is really nice too! The only thing I didn't like was the cheap looking tin covers to the sides of the handle and the tiny feet that failed to clear the height of the handle on my 212 cab.

    Mr Guillaume Maybon18th Feb 2020

    Product looks working well with a great and warm sound, really great with my gibson instead the boots is mandatory for fender single coil . Simple easy to use, good first start for a valve Head amp. I hardly suggest a 12’’ cab
