I've never had the need for an Impedance Buffer, but would just like to say that Joe built me a pedal a little while ago, (another prototype) and it sounds awesome, and Joe has been really helpful with my enquiries.
The quality of his work combined with (what will be) decent prices (once out of the prototype stages) points to a rather succesful future, whether he takes this full time, or just a part time project.
All in all, fantastic work Joe, am looking forward to your future creations
