I have heard concerns expressed about the fact that most right
hand constructed acoustic guitars( in the Martin / Gibson tradition)
have top braces which are asymetrical. The question is whether the
reversing of string gauges will affect the tone of the
guitar , and if so will it be a negative effect?
In my experience the effect is certainly not bad , in
fact I haven't heard a difference. Of course I've done this
conversion on no more than 15 guitars.
But I don't hesitate to do the job.
It should be noted that many builders are now
using a symetrical bracing pattern which negates this concern.
