Yes indeed, works great :-)

The next problem I run into is overdubbing; I'd like to send
my guitar simultaneously to -d and to a .wav file, e.g.
  sox backing.wav -d &
  sox --buffer -c 2 -e s -t alsa hw:4,0 "-d AND gtr.wav"
There are two problems; there's a contest over -d, and I can't
see how to output to -d and the filesystem simultaneously.
Is there an idiom to do this ? Presumably the guitar sox
would have to tee its output off into a play that merged it
with backing.wav

If there's no way, I can always listen to the backing on -d,
and the guitar on headphones plugged into the guitar-effects-box;
but I'd rather hear the guitar through the same hifi speakers
as the backing, if it's not too hard...
