The tools that are available today are fantastic. I ruined all of my Chuck Berry albums by playing a section, lifting the needle, practice it on my guitar, then try to put the needle down without scratching the album. I never quite got the anti-scratching part down!

PS - I just read that BiaB can also do this. I do not do audio in BiaB so someone with more expertise in this area will have to help.
