Thanks so much for all the help guys, but I decided to get a mate to help me on the weekend, I'm just to new at all this to fully understand it and if I do it wrong, that could be the end of me...
On a totally unrelated question though... I just bought a guitar pedal from America and have to use a different power supply then they gave me. I have read something about a voltage converter.
The one I got with the pedal from America says:
INPUT: 100-240V ~50/60hz 0.4a
OUTPUT: 12V - 1.0A
I have this one that was laying around the house:
Arlec Australia - Product Details
Also, I have this one that says:
INPUT: 100-240V AC 50-60HZ
OUTPUT: 9V DC 1000ma
Can I use either of these? Thanks
