1. Power Switch
On / Off Switch for mains power to the amplifier. Please ensure the amplifier is switched off and unplugged from the mains electricity supply before being moved.

8. Middle Control
Dictates the middle register of the amplifier. Turning this up will make your guitar sound fatter. Conversely reducing the amount of middle in your tone will result in a sharper and thinner guitar sound for a more �scooped� tone.

For connection of the supplied footswitch to allow tremelo to be switched on and off. Note: The tremelo effect will only work when playing through Channel 2.

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

6. 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.

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).

9. Treble Control
Controls the high frequencies of the guitar tone, making your guitar sound brighter when increased. (Note: The tone network is highly interactive and altering one control can change the shape of the sound in relation to the other tone controls. Experimentation is the best way to achieve your desired sounds.)

2/3. Loudspeaker Outputs
These are for connection to either the internal speakers and/or an external load, i.e. speaker extension cabinet(s). (See item 4).

4. Output Selector
Matches the amplifier�s output to the load impedance. With all-valve amplifiers it is imperative that the amplifier is connected to a load whilst in operation and that the impedance selected on the amplifier matches the total impedance of the internal speakers and/or extension speaker cabinets. The two internal speakers are 16 Ohms each. These are wired in parallel giving an overall impedance of 8 Ohms, therefore the output selector should be set to 8 Ohms. If an additional 8 Ohm extension speaker cabinet is used in conjunction with the internal speakers the output selector should be set to 4 Ohms. Note: No additional extension speaker cabinet with an impedance lower than 8 Ohms should be used in conjunction with the internal speakers. 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.

10. Volume I
Controls the overall output level of Channel 1. Note: This channel is voiced for a higher treble response than Channel 2.

7. 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.

11. Volume II
Controls the overall output level of Channel 2. Note: Channel 2 is voiced for normal response.

3. Indicator
The Indicator will be lit when your amplifier is on and will not be lit when the amplifier is switched off.

12. Input Jack

Connects the guitar to Channel 1.

4. Speed Control
Controls the speed of oscillation when using the tremelo effect.

5. Intensity Control
Controls the intensity of oscillation (i.e. the effect depth) when using the tremelo effect. Note: The tremelo effect will only work when playing through Channel 2 of the Bluesbreaker combo.

Note: Though the first input of the first channel is the input that most guitarists use, don�t be afraid to experiment. Some guitar players prefer to mix the two channels together by connecting a short, screened patch lead between the second input of Channel 1 and the first input of Channel 2. If you then plug your guitar into the first input of Channel 1 (item 12), you 1 2 can mix the different tonal INPUTS characters of each channel for 1 2 greater flexibility. (See diagram).

13. Input Jack
Connects the guitar to the lower sensitivity input on Channel 1.

6. Presence Control
Adds higher frequencies to the guitar tone, creating crispness and bite. Turning this up will make the sound more cutting and �present�.

14. Input Jack
Connects the guitar to Channel 2.

7. Bass Control
Controls the amount of low frequencies or bottom end in your tone.

15. Input Jack
Connects the guitar to the lower sensitivity input on Channel 2.
