Congratulations on your choice of the M-PULSE BIG BL OCK 750 as your amplifier and welcome to the MESA/Boogie Family! First we would like to thank you for choosing us as your amplifier company . This is something we never take for granted and you will come to find that we are here to help you sound your best should you ever need help.
P AGE 2 Overview: (Continued) Looking at the Front Panel, it is apparent how logically the controls are laid out before you, creating a simple and intuitive platform for expression. However , don’t let this simplicity deceive you as to the incredible shaping power of this preamp.
P AGE 3 FRONT PANEL CONTROLS: INPUT: This jack is the instrument INPUT which feeds the first tube in the all-tube preamp of the BIG BL OCK . It is set up with enough headroom to handle both passive and active style instruments.
FRONT PANEL CONTROLS: (Continued) OVERDRIVE: ( Continued) Note that the GAIN control is still active when the OVERDRIVE is switched into the signal path. The GAIN control is wired in series with the OVERDRIVE and therefore, it can be used to further fine-tune the amount of overdrive present in the mix.
FRONT PANEL CONTROLS: (Continued) BASS: (Continued) This type of broad band, active rotary control makes it possible to achieve bass characteristics far beyond that of a conventional passive type control. It can increase the low end to an almost absurd level and with a flick of the wrist, dip it to near transitor radio skinniness.
FRONT PANEL CONTROLS: (Continued) FREQUENCY: This control determines the frequency range that the ACTIVE MID control will cut or boost. As mentioned earlier , it covers a broad range that sweeps from the low midrange region to the lower treble frequencies.
FRONT PANEL CONTROLS: (Continued) O.D. MASTER: This control, like the OVERDRIVE, is designed to help you think outside the box. It provides an independent volume control for the OVERDIVE mode, allowing you to preset the level of the overdriven sound and footswitch to it for specific parts.
REAR PANEL CONTROLS: FUSE: This is the A.C. Mains Fuse for the BIG BL OCK 750. REPLACE ONL Y WITH A SLO-BLO TYPE FUSE OF THE PROPER RA TING. THIS IS EXTREMEL Y IMPORT ANT , AS THE BIG BL OCK 750 DRA WS A SUBST ANTIAL AMOUNT OF CUR- RENT A T HIGH OUTPUT LEVEL SETTINGS.
REAR PANEL CONTROLS: (Continued) GROUND LIFT / POST & PRE / DIRECT OUT: (Continued) PRE gives you just the sound of your instrument and no BIG BL OCK 750 enhancement so that an engineer can create their own sound with your unprocessed signal at the console.
P AGE 10 REAR PANEL CONTROLS: (Continued) TUNER: This Rear Panel auxiliary TUNER output is wired in parallel with the Front Panel TUNER output. This provides for Rear Panel interfacing of rack mount tuners, where it is preferable to have all wiring stay in the rear of a rack system.

DIAGNOSING PREAMP TUBE PROBLEMS: At some point it is quite possible that you will experience some kind of minor pre-amp tube noise. Rest assured - this is no cause for alarm and you can take care of the problem yourself in a matter of minutes by simply swapping tubes.
