Brand new to forum. These are mainly for my wife (she is the Worship Minister and leads with guitar), but I am learning and get to play them (moved to these from a Japanese Takamine Supernatural and Breedlove Pro Series). I must say that we love the GO! Had to get 2 so we could take advantage of the First Editions! I have been running sound for about ten years, and these are exceptional on stage! To me, the 618e looks better, and she likes the 718e. We both prefer the Rosewood sound of the 718e.. They are both awesome though.. The 718e is 62 of 100 and the 618e is 85 of 100. We got the 718e on Wednesday, and the 618e about 3 weeks ago.
