Greetings. I am about to cross the pond for a few months and am thinking of taking a small pedalboard with me. If I plug the power supplies for a Pigtronix Infinity Looper, Eventide H9 and Source Audio Bass OFD into a power strip, and then put an adapter on the power strip for a European outlet, am I going to blow anything? All 3 power supplies are external wall wart type. TIA.
