This was all covered in a much larger thread in the General forum, called "Tuners, Empeg, for the use of" or something like that.

To answer your specific question:

- The tuner kits are not for sale yet. They will be soon.

- You cannot just make this yourself from just a set of instructions. Some of the parts are chips which are pre-programmed with copyrighted machine language code. Other parts are hard to obtain in single quantities. You are much better off just getting the kit.

- Yes, it will be a package for sale complete with PCBs and all parts. All you need is your soldering iron.

- When it goes on sale, yes, I think it will be likely that you could purchase one from Patrick even if you live in Germany.
