Basic Operation

The front panel Effect buttons light to show you which effect blocks are active.

—When you're scrolling through programs, they'll change to show you the effects in any displayed program. Once you stop scrolling, they'll return to display of the effects that are active in the currently loaded program.

To bypass any active effect, press its button. The light will turn off and the effect will be bypassed. Press the button again to make the effect active again.

Press and hold down any effect button to display the name of the effect and information about its status in the program (on or off).

External audio gear (guitar preamp, CD player, etc) can be inserted into the MPX G2 audio path via the rear panel Insert Return jacks. The front panel Insert button will light to show you when this connection is active.

To bypass this external connection, press Insert. The LED will turn off and the inserted gear will be bypassed. Press Insert again to make the inserted gear active again.

When the MPX G2 leaves the factory, Insert connections are routed in series between the pre-gain and post-gain paths. (This is the best routing to use when connecting to amplifier effects loops.) You can alter this routing by changing the setting of the Insert parameter in the System: Modes menu. Be sure to read about the three different Insert Modes (FX Loop, Mix and Parallel) in Chapter 5: System Controls.

NOTE: When the MPX G2 is connected to a guitar amp with an effects loop, the Insert button allows you to switch the guitar amp’s preamp in and out of the audio path. When it is out of the path, the guitar signal flows through the pre- and post- gain paths and then directly into the power amp. This allows you to switch between dramatically different tones with a single button push.

The MPX G2 has three dedicated front panel tone controls which allow instant modification of the Low, Mid and High settings of the Dynamic Gain effect in the current program. These controls are analog pots. Changes made with these knobs take place immediately (You don’t have to pass-through the current value- once you move the knob, it “owns” the parameter.)

When any of these controls is moved, the display will briefly show the current values of all three controls, then return to the previous screen. Changed settings can be stored by pressing Store to initiate the Store procedure.

Be aware that in many of the Dynamic Gain effects, these tone controls interact with the analog distortion circuitry, increasing or decreasing the amount of distortion in Low, Mid and High frequency bands.
