This is a bit more detailed than Stand alone or Amp Input Only setup — you’ll be connecting the MPX G2 to both sides of your guitar amp’s preamp section. Care must be taken to match levels on both sides of the preamp properly so the tone of your amp is not affected. By the way, as this setup involves making connections and changing controls on both the front and rear of the MPX G2 and your amp, as well as playing, it might be helpful to have someone help you out with this.

If your guitar amp has a stereo effects loop, skip ahead to Part 1. If your guitar amp has a mono effects loop, set the MPX G2 Main Outputs for mono as follows:

1.Press System twice to display System select: Audio.

2.Press > to select Audio Output Mode.

3.Turn the knob to change the setting from Stereo to Mono.

4.That’s it! Press Program to return to Program mode

Part 1: Setting up the Pre Gain Path (connecting to the amp input)

1.Load MPX G2 program 249 Unity Gain.

2.Plug your guitar directly into your amp and set the guitar volume to a comfortable listening level.

3.Put your amp on standby — or turn it off.

4.Unplug your guitar from the amp and connect the MPX G2 rear panel Send jack to the input of your guitar amp.

5.Connect your guitar to the MPX G2 front panel Guitar input.

6.Set the MPX G2 front panel Input knob to 2 o’clock.

7.Select your guitar’s most powerful pickup, turn the guitar volume control up all the way and play your loudest.

8.Watch the Level and Clip LEDs above the MPX G2 Input/Output knob. If the red Clip LED comes on more than just occasionally during your very loudest playing, back off the Input knob a bit. (With some guitars, the red LED may never come on — that’s OK.)

Now that you’ve got the Input knob set for your loudest playing, feel free to change the controls of your guitar to any settings you like as you audition the MPX G2.

9.Press Bypass to bypass the program. (The Bypass LED will turn on.)

10Take your amp out of standby (or turn it on) and play. The volume and tone of the guitar should be the same as when you were plugged directly into the amp, thanks to the MPX G2 built-in relay bypass.

11.Press Bypass again to make the program active. (The Bypass LED will turn off). Play and compare this level with the bypassed level — they should be very close.

12.With the program active, adjust the position of the MPX G2 Input knob to match the bypassed loudness.

Part 2: Setting up the Post Gain Path (connecting to the amp effects loop)

1.Put your amp on standby — or turn it off.

2.Turn the MPX G2 front panel Output knob down all the way.
