Hard for us to say when it will be delivered as there is quite a queue – it will depend when your dealer placed the order to us.
Best that you contact your dealer – he should have the best idea.
UK mains voltage is supported, so no problem there. We can only recommend the use of our power supply, for obvious reasons. Your power supply manufacturer should be able to tell you if he can handle our pedals. He won't know SPACE, cos it's new, but the power requirements are similar to the TF/MF/PF.
