1. Power Switch
This is the On/Off switch for the mains electric power to the amplifier.
Note: Please ensure the amplifier is switched off and unplugged from the mains electricity supply whenever it is moved!
2. Standby Switch
The Standby Switch is used in conjunction with the Power Switch (1) to ‘warm up’ the amplifier before use and to prolong the life of the valves. When powering up the amplifier always engage the Power Switch (1) first, leaving the Standby switch in the ‘OFF’ position. This enables the heater voltage, allowing the valves to come up to their correct operating temperature. After approximately two minutes the valves will have reached their correct operating temperature and the Standby Switch can be engaged, enabling the HT. In order to prolong valve life, the Standby Switch alone should also be used to turn the amplifier on and off during breaks in a performance. Also, when switching the amplifier off, always disengage the Standby Switch prior to the main Power Switch.
3. Mains Indicator
This purple LED indicator will light up whenever the amp is plugged into the mains and the Power Switch (1) is on.
4. Reverb
This controls the level of the internal studio quality plate emulation reverb that is mixed with the direct guitar signal.
Note: If the supplied footswitch is not connected, the reverb is always enabled and can only be turned off by setting this control fully counterclockwise if the reverb is not required. If the footswitch is connected then the reverb can be toggled on and off allowing the reverb level control to remain where you set it.
5. Master Volume
This control sets the overall output volume of the amplifier.
Tonal tip: It is practical to set this first to suit the venue in which you are playing as the position of this volume largely dictates the optimum positions for the other controls.
Tone Controls
6. Presence
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.
7. Bass
This controls the amount of low frequencies (bottom end) in your tone.
8. Middle
This controls the
9. Treble
This control determines the amount of treble and gives your guitar tone a defining edge as it is turned up.
Dynamic Ranges: Low and High
This single channel amplifier has provision to switch between two dynamic ranges.
The low dynamic range is synonymous with our classic vintage amplifiers in terms of the available gain. In this mode clean to mild/moderate overdrive is attainable depending where your guitar volume is set.
The high dynamic range adds an extra valve gain stage enabling a lot more overdrive capability coupled with a dynamically realistic volume boost with the guitar volume on full. The clean to mild/moderate overdrive tones are still there but will now be found at lower guitar volume settings.
10. Dynamic Range LEDs
These LEDs serve as a visual representation for the current status of the dynamic range selection. Blue indicates the lower dynamic range is active and white indicates the higher range is active.
11. Dynamic Range push button
This button is used to toggle between the dynamic ranges if the supplied footswitch is not used. When the footswitch is used this button still remains functional.
12. Mid Boost push button
This button adds a significant boost to the middle frequencies in your guitar tone. Use it to fatten thin single coils or just because you want to anyway! See which position you prefer.
‘Body’ and ‘Detail’ Preamp Volumes
These two controls are the dual preamp volumes serving to set your preferred gain and allow more extensive tone shaping possibilities for individual guitars and styles. They both work together irrespective of which dynamic range is selected and can be set to whatever positions sound right for you, including one of them completely off if that is your sound. Balancing of these two controls is the secret to a great fundamental tone.
Tonal Tip: as the Body & Detail controls offer so much tonal flexibility, we suggest you initially set the Bass, Middle, Treble and Presence controls at 12 o’clock - and then use them to fine tune your tone once you’re happy with your Body and Detail settings.
13. Detail
This controls the upper mid and treble frequencies of your sound bringing an edge to your tone which defines the identity of your instrument. You can set just the right amount of transient detail to allow your guitar to cut through with all the subtle information that your playing dynamic requires.
14. Body
This controls the lower mid and bass frequencies of your sound bringing fatness and weight to your tone. This is ideal for making single coil pickups deliver a humbucker style bottom end without destroying their inherent higher frequency detail. This control coupled with the Mid Boost button (12) can enable a real rock solid beefy grind for those who choose to truly feel it as they play it!
Tonal tip: Bear in mind there is much dynamic versatility to be had at your fingertips when varying the volume/s and/or tone/s on your guitar rather than leaving them on full. Please take the time to fully investigate their impact on the sound as well. This amp is optimised for this interaction between playing dynamics and guitar volume/tone settings. Try setting the amp so that high gain, medium gain and clean can all be accessed from the guitar volume alone.
15. Input Jack Socket
This high impedance input is where you plug your guitar into the amp. You must use a screened (shielded) guitar cable. Never use an unscreened (unshielded) speaker cable because you will find it very noisy to the point of annoyance. The input to any guitar amplifier is a very sensitive part of the signal path and is therefore susceptible to air born radio interference, hence the need for a screened guitar cable. This screened cable should preferably be of good quality. If you are in any doubt regarding this, your Marshall dealer will be more than happy to help, advise and supply you.
