Ok bit of an update. Looked at the bottom speaker to see if it was labled. Turns out its not a legend, but an Eminence Beta 8ohm. So I plugged into the what I thought was the bottom speakers input, with the 8 ohm out from my Fender and for some reason the sound came from both speakers, wheras with the v-amp it came from just the bottom one when plugged into the same socket.
Sounds AMAZING! With rat pedal going into the fender its much clearer than before. I will still get a multimeter to check but I'm thinking this ones an 8 ohm input as it didnt sound bad/damaged, and didnt harm my fender in any way.
