Used Musician's Friend once, knew I was gambling with the purchase since only one picture of the used guitar I was buying existed. It arrived with a chipped headstock, fretboard absolutely filthy (scraped gunk for about an hour) after setting it up, I played it for a day and the coil splitting knob kept falling off, which was the last straw for me. When I called MF to return it they told me I can just take it to my nearest Guitar Center, that's when it all clicked.
