i recently bought a 6 string peavey grind bass. the bass has no serial number and i am trying to find out more information it. it has the cut out in the lower horn. someone had changed the pickups and did a horrible job .i replaced them with EMG'S and it sounds amazing. for what i have into this bass and the sound i get out of i am extremely happy i would just like to know more about it. if there is a way to figure out where it was built by the cut out ,i was told the cut out was only in certain years and certain factories can anyone help me with this.- the photo was before the emgs were installed
