Product Description

Marshall ED1 Marshall ED1 Introduction Compression is perhaps one of the most useful and versatile effects available to any guitarist who is interested in improving their tone. The purpose of the Compressor pedal is primarily to allow you to modify the sustain and attack of your guitar sound. Using classic variable gain techniques the Compressor will provide masses of clean sustain, which you can utilise whatever your style. The Compressor pedal senses the level of the incoming guitar signal and as the signal level decays the gain of the internal circuitry is boosted to provide extra level and hence sustain. The attack control modifies the dynamic response of the guitar signal (the effect of plucking a string) and allows you to achieve a range of effects from rounded and mellow to percussive and funky. The Compressor also features an Emphasis control which allows you to assign compression and target the frequencies you want to compress. This means that you can, for example, tighten up or compress your bass notes and let your treble notes ring out. The Compressor features a passive bypass for the main signal path to ensure complete tonal integrity and has a quality of tone matched only by its versatility. Here follows a complete run down of The Compressor's features for your information. We have also enclosed a number of suggested settings to help guide you. It should be remembered though that these are only suggested settings and you should really take the time to experiment. Though the Marshall Compressor can produce traditional type effects it is also ideally suited to the player who wants something a little bit different. So take the time to explore the sonic avenues opened to you by the Compressor, you won't be disappointed. Always use good quality shielded leads. Always use 9V regulated DC supply with centre negative. Although it may seem obvious the first action in achieving a good effected sound (be it duration / compression etc.) is to find the perfect bypassed sound. This will then allow the correct level to be set with the effect unit to allow a cut or boost in volume and a realistic tone. On clean channels it is advisable to set the gain (or volume) to a setting of no less than one quarter maximum so as not to get unrealistic results due to any volume dependent tonal shaping on the amplifier preamp. As is inherent in circuits of this type the increase in gain at low signal levels inevitably leads to unwanted extra noise as the circuit gain is maximum when the signal level is minimum. Many players overcome their problem with discerning use of a swell pedal or simply utilising the bypass footswitch during performance. Marshall ED1 Features: Out Jack This is the output of The Compressor and is for connection to the amplifier or to another effects pedal. Emphasis The Compressor allows you to specify which end of the aural spectrum you wish to compress. Select "Hi" if you would like to emphasise the treble in your tone to get that real twang and to compress the bass. This is useful for tight funky low note riffs with stabbing bright chords. Turning toward 'Lo' gives maximum treble compression and hence a 'Lo' emphasis. Volume Controls the volume of the pedal, allowing you to set the pedal for a boost or a drop in volume when in operation, should you so wish. DC Input For input of a 9V DC adaptor (as previously described) should you not wish to use batteries. LED Indicates when The Compressor is in operation. Attack This dictates how quickly compression comes in after pick attack. With this set at minimum you will get a rounder more spongy tone. As you increase the Attack the sound will get sharper and more metallic, which is ideally suited for funky styles. Compression This adjusts the amount of compression. The more you add compression, the more you iron out the peaks and troughs in your sound. This increases the amount of sustain and makes for a smoother guitar tone. In Jack This is the input jack, for connection to your guitar or to another effects pedal. Foot Switch For switching The Compressor on and off. Battery Replacement To replace the battery, open the easily accessed coin screw battery cover plate by loosening screw as shown, then disconnect the battery connector lead. Use PP3 or equivalent battery (for improved battery life use alkaline type) Always ensure that the battery is removed when the pedal is not in use for long periods. Dispose of old battery in a safe place.
