Back in November we were staying at our son's, dog-sitting, while they were on #holiday. I took a #guitar with me, my #Fender #Sonoron #Thinline. It's not a guitar with a great reputation and was deleted from their catalogue within a couple of years. Perhaps one of the reasons for that were the #cheap #Chinese tuners. I was placing the guitar in its case and allowed the neck to fall the final six inches. Unfortunately, it was slightly out of line and a tuner hit the side of the case. The plastic button did not survive. I was amazed to find there's no such thing as a standard #Stratocaster neck. Tuners are sold in sets of six and I found sets that had the separation between first and sixth string of 117mm 119mm and 120mm and, I dare say, the were others available. My guitar turned out to need a 119mm set. I opted for a metal replacement button. I only learned afterwards that I hadn't fitted the string in the way intended with a slot headed tuner.
