The "Big Mac" Valve - The big brother to the "Little
Mac." This valve serves multiple functions as a one-way valve, water trap
and air redirect.
The Big Mac inserts into the bottom of the blowpipe stock
(via zippered bag) and features an Airstream valve that is protected internally
and is easily accessed for cleaning. The section inside the stock allows for
moisture to collect to be dumped later. Last, the right angle redirect forces
air away from the pipe chanter reed delaying the time it takes for moisture to
saturate the reed.
