Today we see many non traditional woods (cherry, walnuts, sycamore etc. being used and many domestic to the area where the instrument was built as compared to the past with the majority of woods being used were the exotics ( rosewood, mahogany, koa etc. from other countries.There are a variety of tonewood suppliers offering it all from domestic to the most sought after exotics that are still available. With that being said I will continue to say that the the tonewoods used on any custom built instrument should be and usually is a customer preference.
