I am left handed and off the scale so ..everything i do is left handed from holding a knife and fork to ball sports jerking off etc etc etc
when i first played a guitar as a lad i played a right handed guitar lefty with the strings as they are , theory being the pickups were arranged to suit the strings and i could not "turn " the pickups around. As you can imagine the hurldes to overcome are huge. Got the hang of it and was able to make my way but was not brilliant , by my own admission.
now i found a beauty of an ibanez (still got both eyes as well) in a left handed model and it litrary is like learning all over again , no synapse paths are the same.
The only shop i have ever walked into that had left handed guitars in stock is music connection, and then prolly less that 5 out of a range of hundreds with what appears to be higher pricing as well. makes sense as the costs are amortised over a shorter production run. My particular ibanez is 30 pounds more expesive left than the standard version as a matter of interest. (not a huge amount in m y case thankfully)
I would think that left handed ppl who move over to doing things right handed are probably not going to get to the same heights of achievement as they would have if remaining left handed. Left handers are over represented in achiveing in racket an ball sports. Research (limited)also indicates that left handers are more IQ endowed than their counterparts. unfortunately there is a down side to this , lefties are over represented in certain neurological abberations and lefties are also over represneted amongst paedophiles ???. what nature gives it taketh away. ALso lefties dont live as long as righties.
Left handers are the most maligned and discrminated against minority in the world yet no one raises a flag about this.
There is an oz guitar company making only left handed guitars
http://www.gaskellguitars.com/ and they making some very sweet axes. Prices a highish but remember these are class acts. Unfortunately no importer to ZA as yet but i do go to euro / NZ now and again so may be bringing one back at some point.
Edit : just voted , cannot believe i am the only lefty playing left that has voted in this.
