I have a '66 Princeton reverb that I installed a new Weber 10f150, and it sounds like ass. Is it the speaker, or could I have possibly installed it incorrectly? What would happen if I switched the wires around? It's very tinny sounding right now, and if I put any OD pedal infront of it it sounds evenb worse. When I plus the amp into my 2x12 cab it sounds great, so I know it has to be the speaker.
