I know, I Know! Yes it is a overkill. But I'd rather pay R244.00 for this power supply than loosing a pedal due to insufficient valtage. The Fuel Tank Junior power supply is so expensive - R1631.22! Another power supply I saw with dedicated outputs to every pedal was R 1069.00! I heard so many stories about daisy chains and power supplies that's not giving enough amps and this then cause the pedals to start behaving in a weird manner. Sorry - I'm not so clued-up on pedals. So I thought rather an overkill than a underkill! I can do with R244.00 for a power supply if I can use it for life. Unfortunately this power supply comes only in 11 amps. I will definitely check the polarity!!! I just don't want to run into trouble. Why I asked if this would work is because I saw these Fuel Tanks and stuff and how expensive they are and thought by myself why not use a normal power supply? Why spend all this money?
