Chapter 8 Convenient Features of the GT-6B

Outputting Sounds Without Effects Applied (Bypass)

The GT-6B features bypass circuitry. By using the bypass, the signal path, from input to output, consists entirely of analog circuitry. To switch to bypass, carry out the following procedure.

Using the Expression Pedal Even When Bypass Is in Effect

You can use Bypass EXP Mode to set the routing of the signals when bypass is in effect; these settings can be made separately for each individual patch.

1.Press [NAME/NS/MASTER] until “Bypass EXP Mode” appears in the display.

* Each time [NAME/NS/MASTER] is pressed, the item that

can be set is changed, following this order:

Name Noise Suppressor Master Bypass EXP Mode Foot Volume Effect Chain.

fig.08-50

2.Rotate the PATCH/VALUE dial to select “On” or “Off.”

Off:

You cannot use the expression pedal while bypass is in effect. The bypass sound does not pass through the AD/ DA converter, and analog bypass sound is output. The analog bypass sound is also output for the direct sound when only CHORUS or REV/DLY is used. (However, the expression pedal affects only the effect sound.)

On:

You can use the expression pedal while bypass is in effect. The bypass sound is output after passing through the AD/DA converter. Also, the direct sound is output after passing through the AD/DA converter even when CHORUS or REV/DLY is used, so you can use the expression pedal to control the volume level for sounds including the direct sound.

3.To save the settings, perform the Write procedure (p. 23). Press [EXIT] to return to the Play screen.

Switching Bypass On and Off

Using the Pedal

When the BYPASS/CTL pedal or the expression pedal switch function is set to “Bypass,” these pedals then toggle between “bypass” or “effect on” each time they are pressed.

The green BYPASS/CTL pedal is lit while the unit is in bypass mode (refer to “Settings for Using the Expression Pedal Switch/CTL Pedal”: p. 46).

Using the Buttons

Each time the panel button [TUNER/BYPASS] is pressed, the unit switches between “Tuner mode (p. 56),” “Bypass mode” and “Play mode.”

Connecting Directly to a Recording Mixer or PA Mixer (XLR Balanced Output)

The GT-6B features balanced outputs that utilize XLR connectors. Although direct boxes are generally used to connect bass (effects processor) outputs to mixers in concert halls and recording studios, you can connect the GT-6B directly to the mixer, which lets you avoid degradations in the sound quality, as well as any additional problems that might occur as the result of connecting multiple devices.

Switching the XLR Output Connector Signals

You can select the signals to be output from the XLR connectors with the OUTPUT SELECT switch on the rear panel.

R-OUTPUT-L: Stereo Output

The GT-6B’s stereo output is output as is, without change. Set the switch to this position when recording in stereo or sending stereo signals to a PA.
