EH-1 Echohead

For over 46 years the Marshall name has been synonymous with the greatest guitar tones in all forms of rock music. Our R&D department has gone to great lengths to ensure that our pedals all exude that essential ingredient – the ‘Marshall Sound.’

Now eight-strong, our range of effects pedals offer the opportunity to augment classic Marshall tones or add Marshall character to any guitar set-up.

In keeping with our world-renowned heads, cabinets and combos, all Marshall pedals have been thoroughly road tested and stomped on countless times to ensure optimum performance and reliability.

Presenting the RG-1, RF-1 and EH-1. In addition to possessing their own unique features, each of the three new pedals boast the following: six digital modes, three parameter controls per mode, passive bypass, stereo outputs and optional control pedal input.

RG-1 Regenerator

The Regenerator is a chorus, a flanger and a phaser all in one sturdy shell. This stereo modulation pedal offers six different modes for you to explore:

Vintage Chorus – A classic chorus, adding mellow sweeps to high speed vibrato and everything in-between to your sound.

Multi Chorus – Based upon Marshall’s classic Supervibe pedal, its unique sweeping pattern allows you to create simple sweeps through to complex ensemble sounds.

Vintage Flanger – The versatile vintage effect let’s you go deep and detune your sound to extremes. Turning up the Regen control causes the effect to soar across your sound, while turning it down creates natural flange effects.

Phaser – A rich phasing effect making your sound swell with energy, creating fluid waves which wash around your tone.

Step Phaser – Adding a crystal staircase to the phaser allowing you to trip around its sweeping textures.

Vintage Vibe – A subtle vibration that swirls around your playing, bringing back memories of a classic sound not yet forgotten.

The Regenerator will entwine itself around your tone while leaving you in full control. It’s every modulation pedal you’ll ever need.

RF-1 Reflector

The cavernous Reflector reverb pedal projects your sound into the third dimension. Six reverbs add diffuse trails to your playing without ever swallowing your tone. It’s stereo outputs create reverbs with wide spacious fields. Connecting an expression pedal to the RF-1 allows you to open up the sound as you play.

Hall – A large, lush reverb, adding smooth diffuse trails to your tone without ever drowning it.

Plate – Recreating the sound of a high quality studio plate reverb, bringing space and presence to your tone.

Room – A small reverb, wrapping a subtle presence round your sound. Spring 1 – Recreates the classic sound of a Spring Reverb with its characteristic pulse and resonant ambience.

Spring 2 – This mode takes the sound of springs and infuses it with a lush reverb that only a digital pedal could, providing you with the perfect combination of old and new.

Reverse – The Reverse mode creates ghostly textures as your notes spill backwards out into space before rushing up to your face.

With controls for Reverb Time, Damping and Level for each mode, you’ll easily find the sound you’re looking for.

EH-1 Echohead

Create pulsing tones and add dense rhythmic textures to your sound. The Echohead features a maximum delay time of 2000ms, stereo outputs and a Tap Tempo input which allows you to externally control the delay time with a simple tap of your foot. In addition to controls for Delay Time, Feedback and Level, the EH-1 offers you six versatile modes.

Hi-Fi– A solid delay line throwing out crystal clear repeats of the input. Analogue – Filters shape the echoes, adding a subtle tone and recreating the sound of the guitar cascading through old analogue delay circuits.

Tape Echo – The narrow bandwidth and unstable whir of a tape delay inspired these ‘old school’ degenerating echoes. The random wow and flutter of an old motor adds a warm organic chorus to the dark textured delays.

Multi Tap – Multiple echoes pulse out of the pedal providing a dense rhythmic sound.

Reverse – Sucking the sound out backwards, the Reverse mode trails out a series of hypnotic repeats creating psychedelic textures.

Mod Filter – Sweeping across your sound, synced to your delay time, a

modulating filter adds movement and depth to the echoes.

The dual outputs offer the choice of using a passive bypass for the main signal path to ensure complete tonal integrity or to allow your pedal to spill-over, permitting your echo to naturally die away.

JCM800 Series specifications

Marshall Amplification is synonymous with rock music, and the JCM800 series is one of its most iconic models. Launched in the early 1980s, the JCM800 series redefined high-gain amplification and became a staple for countless rock and metal guitarists. Known for its raw power and tonal versatility, the JCM800 has left an indelible mark on the music industry.

One of the defining features of the JCM800 series is its pure, aggressive sound. At the heart of these amplifiers lies a high-gain preamp circuit, which delivers a rich, harmonically complex tone that is ideal for modern rock styles. The JCM800 offers a variety of wattage options, typically ranging from 50 to 220 watts, allowing players to choose the right power for their sound and performance environment.

The classic EL34 power tubes serve as the backbone of the JCM800's tone. These tubes provide a warm, dynamic response and a pronounced midrange that perfectly complements the heavy distortion and sustain the amp is known for. The two-channel setup—commonly featuring a "Normal" and a "Overdrive" channel—grants players flexibility in their sound. The Normal channel is perfect for achieving clean tones, while the Overdrive channel unleashes an intense crunch that can be dialed in to suit any style.

Control features on the JCM800 amplifiers are straightforward yet effective. Simple tone controls—bass, middle, treble—allow players to sculpt their sound easily. The added presence and resonance controls enhance the amp's response, delivering everything from bright, cutting tones to thick, powerful sounds ideal for heavy riffs.

Another key technology in the JCM800 series includes the use of PCB (printed circuit board) design, improving reliability while maintaining an accessible serviceability profile. Marshall also incorporates features like series effects loops, allowing musicians to integrate their favorite pedals effortlessly.

The JCM800 has become a beloved choice for many legendary guitarists, with its sound frequently associated with iconic recordings from bands such as Guns N’ Roses, Metallica, and Nirvana. Available in various configurations, including heads, combos, and cabinets, the JCM800 series remains a cutting-edge line of amplifiers that capture the essence of rock music. Its rich history, combined with its powerful features, continues to inspire guitarists around the world. With the JCM800, Marshall Amplification has solidified its status as a pillar in the foundation of rock tone.
