Thanks CharlieC, most helpful (as usual)!

Besides I am using the [Invalid or Expired Link Removed] and I am very happy with it.
To save space on the top I am considering to put the stompbox like wireless receiver RXS06 of the G30 set underneath the Pedaltrain Nano. Can anyone who owns the Pedaltrain Nano tell me what the exact distance is between the two parallel bars on the bottom of the Nano? The RXS06 is not high and would for sure fit underneath the Nano in that respect. I guess this from what I could find on the internet, i.e.
setup similar to putting a power supply such as the
setup underneath the Nano or this

Fuel Tank Junior. However, the G30 RXS06 width is 8 cm (3.15 inch) and the output cable plugs into its side, i.e. adds to the 8cm and I fear it might get tight there. Can anyone help me?
