Hi,

I am working on this very device at this moment.

It is very possible to make a strummer for the guitar that is foot powered via a pedal. Similar to a Hi-Hat cymbal or a bass drum pedal. Lonesome Gillette has a system that works very well for him that ( As I deduce by looking at his operation) involves a series of capos with a guitar in open tuning. I heard him play in Boston and it is an amazing thing.

The biggest draw back to the solution as I am able to find is not whether it is possible to build a strummer for certainly it is, but rather one of expectation by the user. I can build something that works. It can't return the player to the player they were.

I know this so frustratingly well from personal experience. Re-attached fingers that work are miraculous. That I can still play at all is another miracle.

I can only say I'm on the case.

Don
