From Jim Marshall
I would like to personally thank you for selecting one of my Limited Edition JCM800 2203ZW Zakk Wylde Signature Series heads. This is only the second time in Marshalls 40-year history that a name other than mine has appeared on one of my products the first being the Slash Signature Series 2555SL Limited Edition in 1996. The amplifier you have just acquired is a reissue of the 100 Watt JCMhead. It was initially launched in March 1981 and proved incredibly popular with rock guitarists throughout the 80s. The limited edition 2203ZW head is totally faithful to the original in terms of tone and feel, but features a quartet of 6550 power valves as opposed to the more commonly used EL34s, as the 6550s are Zakks power valves of choice. This amplifier also has a unique and eye-catching look that was created in collaboration between Zakk and my design team. I first became aware of Zakk in 1988 when he was recruited by the legendary Ozzy Osbourne. Although he was still only a teenager at the time, it was very clear from his excellent guitar work and tone on the No Rest For The Wicked album, that he had a very bright future ahead of him. Although he is an extremely aggressive player by nature, Zakk is always in complete control and, like all great musicians, he knows when not to play. He has a fantastic picking technique and this coupled with his excellent left-hand vibrato, unique use of pick-induced harmonics and highly expressive Wah-Wah work has given him one of the most distinctive styles and sounds in modern rock. So much so that you can tell if Zakk is playing on a song after only hearing a few bars of it! Having followed Zakks career with great interest Ive been especially impressed with his unbending desire to stay true to what he believes in, regardless of what trends are proving popular around him. "Youve got to play the music you dig and believe in," he told me on one of his many visits to my factory in England. "Grunge was at its peak when I did the Pride and Glory album in 1994, but I wasnt about to follow what was going on. Why? I actually like being me!" After Pride and Glory, Zakk released his critically acclaimed acoustic album, Book of Shadows, in 1996. He then formed his hard-hitting Black Label Society (BLS) in 1998 and theyve become one of the busiest bands around. In fact, at the time of writing (Jan 2002), theyd just completed their fourth album, 1919 Eternal. In 2001 Zakk also helped Ozzy record his latest release, Down To Earth. With both bands touring the world this year, 2002 could well be the busiest period thus far in Zakks already hectic career! As Zakk states in his introduction to this manual, hes been a 2203 devotee from day one and the amp has definitely become a vital part of his unique sonic signature. For these reasons Im delighted to offer you this Limited Edition JCM800 2203ZW Zakk Wylde Signature Series head. I would like to wish you every success with your new amplifier and welcome you to the ever increasing Marshall family.

Front Panel Features

1. Power Switch

This is the On/Off switch for the mains power to the amplifier. Whenever it is switched On, the switch will light. Please ensure the amplifier is switched off and unplugged from the mains electricity supply before being moved.

Rear Panel Features

5. Middle Control
This controls the all-important mid-range of your sound. Turning this up (clockwise) will make your guitar sound fatter and fuller. Conversely, turning it down (anticlockwise) will reduce the mids in your sound, giving you that aggressive scooped tone that is a staple of thrash and nu-metal guitar playing.
Effects Loop Send & Return Jacks
To increase the flexibility of your 2203 even further, you may choose to add external effects in its Series Effects Loop, which allows direct connection of either floor pedals or rack processors, with the Level switch (1) providing the correct operating level.
cabs, the amp should be set to 4 Ohms. Failure to comply with these points will result in damage to the amplifier. Your amp should be completely powered down before the selector is turned.

2. Standby Switch

The Standby Switch is used in conjunction with the Power Switch (item 1) to warm up the amplifier before use and to prolong the life of the output valves. When powering up the amplifier always engage the Power Switch (item 1) first. This allows the application of the voltage required to heat the valves to their correct operating temperature. After about 2 minutes, when the valves are up to the correct temperature, the Standby Switch can be engaged. Upon doing this the H.T. (High Tension) which is the high voltage required by the output valves to pass signal (and hence produce sound) is applied. To prolong valve life, the Standby Switch alone should be used to turn the amplifier on and off during breaks in a performance. Also, upon full power down, always disengage the Standby Switch prior to the main Power Switch (item 1).
1. Effects Loop Level Switch
This switch offers two different loop levels to enable you to match the type of effect(s) connected to the Series Effects Loop. The higher level (+4dBV: switch out) suits rack processors and the lower level (-10dBV: switch in) suits floor pedals (stomp boxes).

8. Mains Selector

Matches the amplifier mains transformer voltage to the incoming mains voltage. Ensure that the rotary Mains Selector is set to the correct mains voltage applicable to the country where used. If you do not know the mains input voltage contact your authorised Marshall dealer. Your amp should be completely powered down before the selector is turned. Adjustment from 230/220V to 110V or vice versa will require the mains fuse to be changed to the corresponding value as detailed on the rear panel.

6. Treble Control

This control determines the amount of treble and makes your guitars tone brighter as it is turned up. IMPORTANT NOTE: The 2203s tone network is highly interactive and, because of this, altering the setting of one control can change the way the other controls behave. So, dont be afraid to experiment!

2. Effects Loop Bypass

When out this switch completely bypasses the circuitry involved in the effects loop to maintain the amps absolute tonal integrity.

7. Master Volume

Controls the output volume of the amplifier. This allows the user to turn up the Pre-Amp Volume control (8) for maximum gain whilst keeping the amps overall loudness at a desired level.
3. Effects Loop Return Jack
Connect the (mono) output of an external effects processor here.

9. Mains Input

Your amp is provided with a detachable mains (power) lead which is connected here. The specific mains input voltage rating that your amplifier has been built for is shown on the back panel. Before connecting for the first time, please ensure that your amplifier is compatible with your electricity supply. If you have any doubt, please get advice from a qualified person. Your Marshall dealer will help in this respect.

8. Pre-Amp Volume

This controls how hard you drive the pre-amp valves. Turning this control up overdrives the pre-amp and creates a desirable, harmonically rich distortion.
4. Effects Loop Send Jack
Connect the (mono) input of an external effects processor here. NOTE: As a rule, time based effects such as Chorus, Delay and Reverb are best suited for use in an effects loop. Effects involving distortion or Wah Wah arent usually put in an effects loop because they sound best when theyre before the amp (i.e. placed between the guitar and the amps input). This said, when it comes to tone there are no rules!

3. Presence Control

This control operates in the power amp section of your amp and adds high frequencies to your tone, creating crispness and bite. As you turn this control up (clockwise), your sound will become more cutting.
9. High Sensitivity Input
This is the High Sensitivity input of the amp in theory, such an input is supposed to be used for low-output pickups. This said, 99.9% of all 2203 users ignore this and plug guitars loaded with high-output pickups into this input, because it enables them to drive the pre-amp even harder.

10. Mains Fuse

The correct value of mains fuse is specified on the rear panel of the amplifier. Please refer to Important Safety Instructions, page 2.

4. Bass Control

This controls the amount of low frequencies (bottom end) in your tone.
5/6. Loudspeaker Output Jacks
These are for connection to an external load, i.e. speaker cabinet(s). (See item 7). Please refer to Important Safety Instructions, page 2.

11. H.T. Fuse

The correct value of H.T. fuse is specified on the rear panel of the amplifier. Please refer to Important Safety Instructions, page 2.
10. Low Sensitivity Input
This is the Low Sensitivity input of the amp, which was designed for hot (high-output) pickups; we would suggest you try both inputs and then decide which one is best for you.

7. Output Selector

Matches the amplifiers output to the load impedance. With all-valve amplifiers it is imperative that the amp is connected to a load whilst in operation and that the impedance selected on the amp matches the total impedance of the speaker cabinet(s) being used. For example, if the amp is running into a single 16 Ohm cab, the amp should accordingly be set to 16 Ohms. If running into two 16 Ohm cabs, the amp should be set to 8 Ohms. If running into two 8 Ohm

Introduction

The all-valve 2203 is one of the most highly respected and revered 100 Watt Marshall heads in the companys long and illustrious history. Evolving from the legendary 100 Watt Plexi head, it was also our first amplifier to house a Master Volume (MV) control. This simple but groundbreaking feature allowed the user to overdrive the preamp valves into desirable distortion without having to turn the amp full up. This proved to be incredibly popular and practical because, as you probably know, a 100 Watt Marshall is extremely loud when on full volume! Furthermore, thanks to its cascaded preamp design, the 2203 was capable of producing a level of distortion never heard from a guitar amp before. The very first 2203 was actually introduced to the world in 1975. The JCM 800 version that surfaced some six years later, in 1981, was merely a cosmetic redesign of the original. The circuitry remained exactly the same (as the saying goes, "if it isnt broken, dont fix it!"), but the amps appearance got much bolder with a full-width control panel (the 2203 of 1975-1981 had a shorter front panel like a 1959SLP), grille cloth over the front baffle (the original 2203s baffle was covered with vinyl), white piping, and JCM 800 written in bold letters on the front panel, together with Jims signature. If youre wondering about the origin of the JCM 800 name, its an interesting tale it came from the registration/license plate of Mr. Marshalls car which was, wait for it, JCM 800! The JCM part of it referred to Jims initials (James Charles Marshall), the 800 was merely the number on the plate no more, no less! As guitar amplifiers go, the 2203 is the very essence of simplicity its a one channel amp with no reverb or built-in effects and its all-valve design produces a sound that, as Mike Doyle so aptly describes in his excellent The History of Marshall book, is "crunchier than a lorry running over a hedgehog!" As a result of its idiot-proof interface, distinctive roar and larger-than-life edge, the 2203 immediately set the standard by which all other rock amps were judged and it remained the industry benchmark throughout the entire 16 years of its production life. ENGLISH The unparalleled new tones the 2203 generated immediately became the sonic impetus that helped drive forward the veritable explosion of hard rock acts in the late seventies and early eighties. The JCM 800 incarnation of the amp (along with the other models in the JCM 800 range, most of which were derivatives of the 2203) quickly became the mainstay of the burgeoning heavy metal scene that dominated the 80s and was the amp responsible for many of the seminal thrash metal recordings of this period. In fact, Kerry King and Jeff Hanneman of Slayer, a hugely influential band that helped pioneer the thrash genre, still use their Marshall 2203s to this very day. The late eighties and early nineties saw a shift towards the alternative/Brit pop movement in the UK, while the US was dominated by the grunge scene. The wide-ranging use of 2203s in these extremely varied musical genres is a true reflection of this amplifiers extremely versatile tonal range. With the launch of Marshalls hugely popular JCM 900 Series in 1991, the JCM was deservedly, but somewhat reluctantly, put out to pasture after 16 years of sonic supremacy. Despite its retirement though, the 2203 continued to be a much sought after amp and scores of players, including that brilliant fretburner Zakk Wylde (of Ozzy Osbourne and Black Label Society fame), would relentlessly hunt down old 2203s for use in the studio and on stage. Owing to the seemingly never-ending barrage of requests we receive on a daily basis for the 2203, weve decided that it is time for us to relaunch this great amp in its most popular guise the JCM 800. Furthermore, by popular demand, weve also given it a Series Effects Loop that features a true Bypass switch that takes the loop completely out of the circuit, thus ensuring the original tone isnt compromised in any shape or form.
