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. | ||||

OVERDRIVE
This is especially important because overdriven sounds are more compressed than clean sounds and as greater amounts of overdrive are added, it will compress the signal more, making the relative volume to the normal mode seem lower.
NOTE: The OVERDRIVE LED will illuminate when the OVERDRIVE mode is activated with the Footswitch indicating that both the OVERDRIVE and O.D. MASTER are in the signal path and active.
POWER SWITCH: This switch delivers the A.C. power to the BIG BLOCK 750. Make sure the unit is grounded (all three terminals of the A.C. power cord must be connected whenever possible to avoid injury to the user as well as to the amplifier). Also, make sure that the proper voltage requirements are present at the A.C. wall socket receptacle.

AC OFF
NOTE: As a reminder, never alter the A.C. power cord in anyway for possible damage to the amplifier may occur not to mention the possibility of a fire outbreak.
Now that we have reviewed the features and controls on the Front Panel, let’s take a spin around back and review the interfacing connections.
