The EV-30 and EV-5 can be used.
* We recommend using the EV-30 with the SPD-SX PRO. For details, see “Connection-related points of note”.
You can control the effect intensity and so on by plugging an expression pedal into the HH CTRL/EXPRESSION jack of the SPD-SX PRO.
For details on the settings, refer to “Configuring the Functions to Assign to the Pads and Footswitch, and Configuring the PAD EDIT Knob and Expression Pedal Settings for the SPD-SX PRO Overall (CONTROL SETUP)”.
Connection-related points of note
When you connect the TRS cable (the cable with an L-shaped plug on either end) that’s included with the EV-30 or connect the EV-5 cable (L-shaped plugs, non-removable), one of the jacks next to the HH CTRL/EXPRESSION jack is obstructed.
For the EV-30, you can resolve this issue by using a straight type TRS cable (commercially available, sold separately).
