100W, 1-channel Tube Guitar Amp Head with Tight Switch, Midrange Boost, and Gain Boost

A Modern Modification of an All-time Marshall Classic

True to the JCM800’s hard-rocking roots but not afraid to innovate, the Marshall JCM800 Modified celebrates a timeless Marshall classic with a host of modern, performance-minded appointments. From fueling the heavy metal of the 1980s when it first launched to its role as an alternative and punk icon in the 1990s all the way up to its status as a modern mainstay, the JCM800 boasts one of the most revered and recorded tones in guitar history. As such, the JCM800 Modified retains the rock-solid foundation of the original, mirroring its 100-watt power rating, straightforward EQ section, and gain-laden one-two punch of Master Volume and Pre-Amp Volume knobs. However, the eagle-eyed in the audience will no doubt notice the additional switches set directly under the control section — these powerful tonal tools unlock a cutting midrange boost, a fiery gain boost, and a tight switch to firm up your bass when dishing out ripping riffs and rhythms. Revised and ready to rock with even the most modded-out Marshalls, the JCM800 Modified elevates an all-time rock and metal classic without compromising on the style and sound of the original.

Turn up the heat

The JCM800 Modified’s first departure from vintage specs comes in the form of a high-octane gain boost switch. Flip this switch, and the JCM800 Modified’s already-formidable roar is boosted with a powerful injection of saturation, allowing you to effortlessly swap from old-school rock and blues tones to ultra-aggressive modern metal mayhem.

Clarity-enhancing midrange boost

Ask any of Sweetwater’s rocking lead players how they cut through the mix, and they’ll tell you that the secret lies in the midrange. It’s what gives your tone its cut and bite, and the JCM800 Modified’s powerful midrange boost switch might just save you the trouble of rigging up a green-colored stompbox. Lay down the rhythm with JCM800’s time-tested, authoritative crunch, then engage this switch to instantly transform your signal into a screaming, solo-ready sound with enhanced depth, warmth, and articulation.

Tighten up your tone

When the JCM800 was first released in the early 1980s, low-tuned guitars had already been a staple in rock and metal for more than a decade. Still, with the rise of extended-range instruments, subterranean tunings, and extra strings within the realm of modern rock and metal, it can often be a challenge to keep your low end in check on older amp designs. Well, unless you’re rocking the JCM800 Modified, anyway — this amp’s tight switch surgically cuts out excess bass, keeping your chugging rhythms and riffs crystal clear in even the highest-gain scenarios.
