1 Mark6120 3 months ago I brought my new Eddie Cochran Gretsch to my guitar tech to make sure it was setup properly and to help me tune it. Seems it drops a half step every few days and all string go flat. He assured me that the strings just needed to settle in. He also told me that my guitar had a compensated bridge that was designed for a wound G string. I cant find any info online to confirm his observation. I know that Eddie played a plain G string. I'm wondering if Gretsch placed the wrong bridge on my guitar and does it really matter.
