My Boss adaptor was not work anymore recently. i just concern about that if i use other adaptor instead of Boss adaptor, would there really be any malfunction of damage to the compact pedals? Or is it a must to use Boss adaptor to connect with my compact pedals?
It doesn't have to be a Boss PSA adaptor. Any 9V adaptor will work but many Boss pedals will become noisy if the adaptor isn't good quality so it's wise not to buy the absolute cheapest model.
