Thanks Darth Matth ;)
Yes both the ANH and ESB sabers are "verrry nice" (to say the least). I am planning on buying one of each, 1xANH & 1xESB Graflex saber from Master Yoda (when he has them available of course), both sabers with the crystal chambers and ideally both with the crystal focus sound boards.
I have seen videos on Youtube of people having Graflex ANH sabers with crystal chambers and crystal focus boards, however they had the aux button at the bottom of the hilt coming out of one of the sound holes which seems to work but sacrifices the external look of the hilt. These I believe were from Erv. Still very nice sabers as well.
Yes, Master Yoda is very powerful indeed. I hope it is possible and Master Yoda finds a way to have the best of both worlds (sounds + looks) with the ANH Graflex sabers.
