What was your first tweak?

Yes, nickels on the headshell seemed to be the right weight for my TT...anyone remember wedging a match book either under or above the 8 track while it was playing so it sounded right? Just loved the click to a new track right in the middle of the song while you were listening.

Speaker cable's. I know it's not considered a tweak now but in 1972 it was, friends and family scoffed and laughed at the high quality, thick cable that had no terminated ends just bare wire. There wasn't much of an improvement in sound quality but it was inexpensive and that was important at that time. Later on, a few year's after CD players came along, putting Black Diamond cones under and removing them from the player stopped everyone in their track's, audiophile or not. I still bevel cut and green pen the edges of the little silver devil's.

Generic Tip-Toes under my Adcom 565's.

Tube Coolers. They didn't actually do anything but seemed like a good idea at the time.
