Soul Preacher Buffer Question

[Peppercorn]

Hi everyone, this is my first post here but I've done plenty of reading, however I cannot find an answer for this

I am attempting to build a "Soul Preacher" Compressor pedal. I seem to understand the assembly generally and have bought the necessary components however,
If you look at the photo of the layout here
http://www.aronnelson.com/gallery/main.php/v/MarkMs-Gallery/album15/album76/Soul_Preacher_revision_7_LAYOUT.gif.html

You'll notice that there is an output on the 2nd lug of the Vol pot. which I can understand, but there is also a spot on the pcb called "A" which equals "Buffered Output"

I have no idea what Buffered Output is and what it should be used for. Can anyone shine some light on this for me please???

Thanks in advance for any help!

Thanks all, I have just found the answer to this! For those that "may" want to know, it's a low impedance output to drive the input of another equipment without loss of signal.

Sorry for any waste of time!
