HI,
I JUST PURCHASED A NEW EPIPHONE STUDIO LT FROM AMAZON. I HAD TO EXCHANGE IT 4 TIMES AS EACH GUITAR THEY SENT WAS OBVIOUSLY WORN OUT. FINALLY I GOT ONE THAT LOOKED NEW AND I KEPT HER; BUT AFTER 3 WEEKS I'VE NOTICED A BUZZING PROBLEM EVERYTIME I TOUCHED THE STRINGS.
I WATCHED SOME VIDEOS ON HOW TO FIX THE GROUND ISSUE WITH A GUITAR. I FOLLOWED THE INSTRUCTIONS AND EXAMINED ALL THE POSSIBLE CONNECTIONS WITH RESISTENCE AND CONTINUETY SETTINGS ALIKE. ONLY 2 POINTS WERE DISCONNECTED; THEY WERE THE OPPOSITE ENDS OF THE SAME WHITE CABLE THAT ON ONE END CONNECTS TO THE JACK OUTPUT SOCKET AND ON THE OTHER END TO PICKUP SELECTION SWITCH. PARALLEL TO THE WHITE CABLE RUNS ANOTHER WIRE (I'LL JUST CALL IT BLACK FOR A LOSS OF PROPER TERMINOLOGY) - THE TWO ARE IN A COMMON BLACK ISOLATION/CABLE. THE BLACK ONE IS LIKEWISE CONNECTED ON ONE END TO THE JACK OUTPUT AND ON THE OTHER TO THE PICKUP SWITCH. WHEN I CONNECT (WITH VOLTMETER) THE BLACK ONE WITH ANY OTHER METAL PART (EXCEPT FOR THE TWO ENDS OF THE WHITE WIRE) THE CONTINUITY AND RESISTENCE ARE CONFIRMED. WHEN ON THE OTHER HAND I CONNECT THE WHITE WIRE AT EITHER END (OUTPUT OR SWITCH) TO ANY OTHER METAL PART OF THE GUITAR NO RESISTENCE OR CONTINUITY IS ESTABLISHED. I'VE ADDED TWO PHOTOS SHOWING THE TWO WIRES (WHITE - PROBLEMATIC ONE AND "BLACK") ON THE TWO OPPOSITE ENDS.
BASED ON THIS OBSERVATION I ASSUME THE WHITE WIRE MUST BE BROKEN SOMEWHERE IN BETWEEN AND I NEED TO REPLACE IT; BUT AS I AM A COMPLETE NEWBIE, WHO JUST OPENED A GUITAR FOR THE FIRST TIME, I'D LOVE TO CONSULT SOME OF YOU VETERANS OUT THERE HOW TO TACKLE THIS IN ORDER NOT TO DESTROY ANYTHING. ANY SUGGESTION IS HIGHLY APPRECIATED.
THANKS
