Thank you Luis ! Yes I have experience in electronics, I develop point of same terminals (hardware and firmware). About metal working I know how to use a drill, a dremell or files but really this is my first time making a metal mechanism. Remember that the most visible part of the tuner are the pegs and they were made by a friend in his lathe.
This morning I was thinking about the case for this baby, the idea is something soft or almost to carry the guitar, amp, AC-DC converter, cable, etc. I asked to my wife and my mother and they said me that in order to maintain all this project mine I have to learn how to sew !
OK, another thing to learn !
Only one question, is there any incompatibility if a guy sews and plays rock with an electric guitar ?
