When I was a kid, I showed a great interest in music and I asked my folks for a guitar for my 9th birthday. Once they had bought me an acoustic, we went to a local guitar teacher and she asked me to hold my guitar naturally. Instinctively, I held it left handed. So she strung it up for me left handed.
This was the very worst advice she could have ever given.
Being a lefty on guitar means that my options for buying an instrument are severely restricted by the manufacturer. And any instrument that is made lefty has an upcharge, sometimes upwards of 25%. A nice lefty is a special order and takes at least 3 months to get made.
I can’t go into a music store and just pick up an instrument and start playing. I can’t swap out a guitar with my friends.
The resale value of a lefty is questionable, because it depends on how many lefties are in the market, and it’s far fewer than the alternative.
If only that lady had advised me to go against my instincts and learn to play right handed…
