Hi Joe,
I see you have tracked me down! Hope you don't mind me mentioning your Juno Stage on the post!
PS. Don't tell John Sweeny I said you don't have to use Roland adaptors , but you really really don't.
I heard you! Just wait until I see you tomorrow! I assume you are still coming in to see me? Just for the benefit of everyone else though.... should you choose to use an adaptor other than the supplied one from Roland (or a direct replacement from Roland) then we would not entertain any warranty claim where damage had been caused by the non-standard power supply
