Markbass MB7 Booster



The MB7 Booster pedal has a cool, compact design and combines a useful clean boost (very handy for helping you stand out when taking a solo) with a 7-band graphic EQ (to tailor your bass tone to perfection)!

Clean boost

A clean boost of up to +20 dB instantly gives you more clean headroom any time you need it.

7-band graphic EQ

The seven-band graphic EQ is very useful for modifying the tone of your instrument, giving you an sound option at the press of a switch. The adjustable frequencies range from 40 Hz to 4 kHz, giving you powerful control of your bass tone, even for 5 and 6-string basses. Each band can be boosted or cut over a +/-16dB range. This can also be used to help eliminate unwanted feedback when playing acoustic instruments.

True bypass

Like all our pedals, the features “true bypass”: that means that when the distortion is “off”, your signal goes directly from the input jack to the output jack without any degradation of audio quality.
