You can connect an external effects processor between the SEND jack and RETURN jack, and use it as one of the GX-100’s effects processors.

The sound that is input to SEND/RETURN within the effect chain will be output to the SEND jack. The sound that is input via the RETURN jack will be input to SEND/RETURN within the effect chain.
| Parameter | Value | Explanation | 
|---|---|---|
| ON/OFF | OFF, ON | Turns this effect on/off. | 
| MODE | NORMAL | The input to SEND/RETURN within the effect chain will be output to the SEND jack, and the input from the RETURN jack will be output following SEND/RETURN. Use this setting if you want to connect an external effects processor in series within the GX-100’s effect chain.   | 
| DIRECT MIX | The input to SEND/RETURN within the effect chain will be output to the SEND jack, and the input from the RETURN jack and the input to SEND/RETURN (the direct sound) will be mixed and output following SEND/RETURN. Use this when you want to mix the GX-100’s effects sounds together with the sound with the external effects device applied to it.   | |
| BRANCH OUT | The input to SEND/RETURN within the effect chain will be output to the SEND jack. The input from the RETURN jack will be ignored. For example, by placing SEND/RETURN in the GX-100’s effect chain in front of reverb or delay, this allows you to use the SEND jack as a dry out.   | |
| SEND LEVEL | 0–200 | Adjusts the volume of the output to the external effects device. | 
| RETURN LEVEL | 0–200 | Adjusts the volume of the input from the external effects device. 
 | 
| ADJUST | 0–100 | Adjusts the phase between the GX-100’s internal processing and an external effect unit connected to the SEND/RETURN jacks. 
 | 
| INVERT | OFF, ON | Inverts the phase of the signal sent from the external effect to the RETURN jack.
