Pre-wired electronics Our MB INSTRUMENT PRE P is bundled with the same additional controls and wiring that are featured on our Markbass instruments. The VOLUME / VOLUME / TONE control pots are clearly the best choice to manage two pickup configurations, and the push/pull TONE control pot lets players quickly move from Jaco or Motown voicing to more modern and open tones - even when switched to passive mode. When in active mode, the BASS / MIDDLE / HIGH control pots on the 3-band EQ section augment the character of your instrument adding modern, rich responses when boosting or cutting your selected frequencies delivering a balanced and defined tone even at extreme settings.
Active/Passive mode Changes in the volume level when switching from Active to Passive and back again are almost imperceptible - a unique feature of the exceptional circuitry inside which all musicians will appreciate.
Ultra-compact size The MB INSTRUMENT PRE is remarkably compact, allowing it to fit easily into the control cavities of most instruments.
Optimal sound reproduction Our preamp consistently delivers an authentic reproduction of your sound - even at extreme settings, without sacrificing the tone details of your instrument across the entire frequency range.
9v or 18v, low power consumption The MB INSTRUMENT PRE can operate on either 9V or 18V (Using either 1 or two 9V batteries). Due to its lower power consumption - about 700uA in a 9V configuration - the preamp offers exceptionally long battery life.
