From The Chairman  
I would like to personally thank you  
for selecting one of our effects pedals.  
Clean only with dry cloth.  
For over 40 years the Marshall name has been synonymous  
with the greatest guitar tones in music. We have worked hand  
in hand with guitarists from all levels throughout the world to  
maintain and improve that special ingredient, ‘The Marshall  
Sound.’  
Note: This equipment has been tested and found to comply with  
the limits for a Class B digital device, pursuant to part 15 of the  
FCC Rules. These limits are designed to provide reasonable  
protection against harmful interference in a residential  
installation. This equipment generates, uses, and can radiate  
radio frequency energy and, if not installed and used in  
accordance with the instructions, may cause harmful interference  
to radio communications. However, there is no guarantee that  
interference will not occur in a particular installation. If this  
equipment does cause harmful interference to radio or television  
reception, which can be determined by turning the equipment off  
and on, the user is encouraged to try to correct the interference  
by one or more of the following measures:

Our range of effects pedals gives the opportunity to augment  
the classic Marshall tone to add Marshall character to a guitar  
set-up.  
All our pedals are made with the same utmost attention to  
quality, in both materials and manufacture as our world  
renowned amplifiers, cabinets and combos, in order to provide  
you with optimum reliability and tone.  
• Reorient or relocate the receiving antenna.  
• Increase the separation between the equipment and receiver.  
• Connect the equipment into an outlet on a circuit different  
from that to which the receiver is connected.  
• Consult the dealer or an experienced radio/TV technician for  
help.  
I would like to wish you every success with all of your musical  
endeavours and also your new Marshall effects pedal, which I  
am sure you will find a pleasure to play for many years to  
come.

Changes or modifications not expressly approved by Marshall  
Amplification plc could void the user’s authority to operate the  
equipment.  
Heed all warnings.  
Follow all instructions.  
Keep these instructions.  
Yours Sincerely,  
European Product Only

Mod Filter Sweeping across your sound, synced to your delay  
time, a modulating filter adds movement and depth  
to the echoes.  
3. 'Out 1 / Left' Jack Socket - Passive Bypass  
Out 1 is connected to a passive bypass circuit. The passive  
bypass ensures complete tonal integrity by disconnecting the  
output of the effects circuit when not in operation. When a  
jack is connected to Out 1 the pedal operates in mono mode.  
6. Delay Time  
Controls the delay time of the echoes from 20ms (fully anti-  
clockwise) to 2000ms (fully clockwise).  
4. 'Out 2 /Right' Jack Socket - Spill-Over  
Out 2 is connected to a spill-over circuit. When the pedal is  
switched off the echoes it has produced are allowed to 'spill'  
and naturally decay over your playing while the input feeding  
the effects circuit is switched off. When a jack is connected to  
Out 2 the pedal operates in mono mode.  
7. Feedback  
Controls the amount of output signal that is fed-back and  
mixed with the input increasing the time taken for the echoes  
to decay. Fully anti-clockwise no signal is fed back and only  
one echo is repeated, fully clockwise and the entire signal is  
fed back causing the echoes to sound indefinitely.  
When jacks are connected to Out 1 & Out 2 the pedal operates  
in Stereo mode, producing a ping-pong style delay between  
the two outputs. In stereo mode the delay time of Out 2 is half  
the length of Out 1. No spill-over is present when the pedal  
operates in stereo mode.  
8. Level  
Controls the level of the overall effect. Fully anti-clockwise  
gives the least effect and driest (uneffected) guitar signal,  
while fully clockwise gives the most effected guitar sound.  
5. Mode  
9. Foot Switch  
For switching the Echohead on and off.  
The Echohead offers six different delay modes. Selected by  
switching the mode knob in to one of the six positions.  
10. LED  
Hi-Fi  
A solid delay line throwing out crystal clear repeats  
of the input.  
Indicates when the Echohead is in operation.  
11. DC Input  
For input of a 9V DC centre negative regulated adaptor should  
you not wish to use batteries.  
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 harsh 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.

Trouble Shooting  
Battery Replacement  
1. To replace the battery, open the easily accessed coin screw  
battery cover plate by loosening screw as shown, then  
disconnect the battery connector lead.  
2. Use PP3 or equivalent battery  
(for improved battery life use  
alkaline type).  
3. Always ensure that the battery  
is removed when the pedal is  
not in use for long periods.
