Marshall Amplification B 30, B 150, B 65 specifications Suggested Settings

Suggested Settings

Before we look at some suggested settings there are a couple of points that you should remember;

1- Taste in sound is a very personal thing. What might sound great to one bass player might not appeal to another bassist. Therefore these suggested settings may need some alterations to suit your own personal taste.

2- One of the main influences on your sound will be your bass.

B30

Each bass displays certain tonal characteristics, some for example will sound brighter than others while others may sound bassier.

For this reason again you may find that these suggested settings need some alteration to give the required sound.

Here then follows three simple settings for both the B30 and the B65 suitable for Slap, Fingers and Plectrum styles.

We hope that these settings provide you with a useful starting point to develop your own killer bass tones.

This input is designed to take the signal from an active bass. If your bass guitar is active plug in here. We recommend that you always use a high quality screened cable to help prevent noise, interference and unwanted feedback.

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.

6. Deep Switch

Push switch to add extra bottom to the low end of the primary EQ.

7. Treble

By adjusting the Treble control you can add or take away the higher frequencies in your bass tone. By increasing the amount of treble you will make your tone brighter, ideal for percussive styles of

This input is designed to take the signal from a passive bass. If your bass guitar is passive plug in here. We recommend that you always use a high quality screened cable to help prevent noise, interference and unwanted feedback.

-Though the above inputs were designed around the signal from an active bass and a passive bass guitar respectively, you should experiment to see which input best suits your style. Don’t worry, connecting your bass to the ‘wrong’ input will not harm your Bass-State™ or your bass guitar.

3.Gain

This controls the amount of input from your bass and the amount of input from the pre-amp to the power amp. If you require a clean bass sound turn this control up until your bass just starts to distort and then back it off slightly. If on the other hand you would like a distorted sound, simply turn up the Gain control until the required amount of distortion is achieved. Another tip, for those of you who have got active basses who want a distorted tone, is to try plugging your bass into the Passive Input. This will cause no harm and may provide the sound you are looking for.

4.Blend

With the B150 it is possible to blend your signal between a valve and/or solid-state input pre-amp section. Each type of pre-amp produces a different character of sound, valve pre-amps for example tend to give a very warm tone while solid-state pre-amps give a harder, snappier response, ideal for more percussive styles of bass playing. As these circuits are blendable, it is possible to have degrees of both types of pre-amp in your signal, to combine the best of both worlds.

5. Bass

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

playing.

8. Bright Switch

Push switch to add brightness and attack to the top end of the primary EQ.

9. Compressor

The Compressor smoothes out your bass sound. As you increase the amount of compression, so you flatten out the peaks in the signal.

10. Compressor Active LED

Indicates whether the Compressor is in operation.

11. 7 Band Graphic

To allow you to further tailor your sound, with the Graphic it is possible to cut or boost 7 specific frequencies. If you do not want to alter the shape of your sound with the Graphic simply leave the sliders set to 0.

12. Limiter

Traditional amplifiers when run at high volumes will begin to clip or distort. The Limiter facility when in use will prevent the power amp clipping at high volumes and at low volumes will have no effect.

13. Volume

Controls the overall volume of the B150.

- Effects Loop-

An effects loop is used for connecting an external effects processor or floor pedal. The effects loop on the Marshall B150 is compatible with the output level of either type (processor or floor pedal) to ensure that a perfect match is made.

14. FX Send

For connection to the input of an external effects processor or floor pedal.
