600 Series Changes
(January 2008) As of the beginning of 2008, Walden is replacing the D610, D610CE and D610L steel-string guitars with the D600, D600CE and D600L. The only difference between these two model numbers is that theD610s had solid Engelmann Spruce tops and the D600s have solid Sitka Spruce tops.
Also, the N610 and N610CE classical guitars are being replaced by the N660 and N660CE. The N610s had solid Engelman Spruce tops and the N660s will be built with either solid Engelman Spruce or solid Sitka Spruce, based on availablity of quality materials.
These model changes are a result of the decreasing supply of affordable, high-quality Engelman Spruce.
