User manual MARSHALL AMPLIFIER MB15

[. . . ] ENGLISH From Jim Marshall I would like to thank you personally for selecting one of our new MB Bass amplifiers. As a musician myself I fully understand the necessity of achieving the right tone and feel to help inspire musicians to reach their full creative potential ­ be they aspiring beginners or more skilled players. With this in mind I set my experienced R&D team the task of designing a new range of affordable bass amplifiers that truly captured the essence of the Marshall sound. Utilising new technologies, some of which were developed for our critically acclaimed AVT range, the new MB Series raises the standard for what can be expected from a value-for-money range of bass amplifiers and defines a new benchmark. Like all the amplifiers in my new MB range, this amp was completely designed and engineered in the UK and the most rigorous quality control procedures ensure that it meets the standard of build you have come to expect from all Marshall products. Whether this is your first ever Marshall or is the latest addition to your arsenal of amps, the tone, flexibility and feel of this compact, rugged combo will deliver the goods ­ from bedroom to backstage! [. . . ] VOLUME Control - Modern Channel This control adjusts the volume of the Modern Channel. Turning the Bass control will effect the amount of low frequencies or bottom end in your bass guitar tone. Rotating this clockwise will increase the amount of lower tones generally making your bass sound deeper. Turning this control anti-clockwise will reduce the bass frequencies in your tone producing a reduction in bottom end thud. MB30 Rear Panel Features 3. COMPRESSOR Switch & LED This switch turns the Compressor control on and off. When the switch is `in' the Compressor control is active and the LED will be illuminated green. 9. VOICE SHIFT Control (MB30 only) This 3 position control adjusts the overall tonal voicing of the amplifier. 4. As you increase the amount of compression, so you flatten out the peaks in the incoming signal. When the compression reaches its threshold the LED will change to red. Position 1 tailors the response of the amplifier for smooth low end, restrained lower mids, and mild high end lift, to give the classic vintage valve bass tone. 1 2 3 4 1. MODERN / CLASSIC Switch This push switch allows you to change between the amp's two channels, Modern and Classic, via the front panel. When this switch is `out' the Modern Channel is engaged and the LED will be green. Pushing it `in' switches to the Classic Channel and the LED changes to red. In position 2 the lower mid is made more prominent whilst simultaneously the upper mids are subtly scooped to give a more aggressive, growling quality to the amplifier's tone. Position 3 introduces a gentle overall mid boost for an immediate, cutting, 'in your face' tone with the mids scooped even further to give an immediate, cutting sound. . . This control adjusts the response selected by the Voice Shift control. On the MB15 the Voice Shift control is similar to position 2 on the MB30. Connect the optional footswitch (PEDL-10008) here enables you to change between Modern and Classic channels. 4. SEND Jack Socket If you want to use an external effects processor in your amp's built-in Series FX effects loop, this is the jack you connect to the INPUT of the unit you are using. You can use this socket to connect the MB30 to your multi-track recording machine and you'll get a great speaker emulated guitar sound direct to disk or tape. HELPFUL HINT: for `silent' recording merely plug an unconnected jack plug into the headphone socket and you'll disconnect the MB30's internal speaker. 3.
