i havent posted on this forum for like 2 years


I have a Fender DeVille 410. A while back, my brother was playing synth through it (which i wouldve never let him do) and it stopped making sound. I told him to fix it, and im not sure exactly what he did but he got it working again, except 1 out of the 4 speakers wasnt making any sound. Still sounded good, so i forgot about it. I realized the other day though that now only 2/4 are making sound. i fear that there is some sortof impedence problem, and that playing it will make it worse. any advice would be greatly appretiated.
