XPND 1: Most standard power supplies will not fit under the smaller XPND 1 pedalboard. For XPND 1, a standard power supply would need to be mounted on top. However, there are a select few small-scale power supplies that are known to fit under the XPND 1 boards. To check if your power supply will fit, please contact us. Alternatively, many players choose to use a daisy chain power supply with XPND 1.
XPND 2: The underside of XPND 2 can fit most standard power supplies. A power supply can be mounted underneath on the non-expanding side. The board comes pre-fitted with Velcro on the underside of the board, so you can easily mount power supplies underneath using Velcro.
