Hello, I would like to buy what is required to make my TC-Helicon GXT (Backing Vocals) work. It has a 12 volts plug!
I would also like to know what type of battery I should get to make it work for at least 4 hours in a row?
Furthermore, I need as well a reverse polarity plug for 9 volts pedals.
As soon as I know I will pass the order!
Thanks for your precious help!
