Some people say a good compressor is one that you can't tell
when it's on or if it's off...This is not one of those compressors.
 If you like an extra squishy compressor that turns you pick
attack to mush, then you will love the Orange Squeezer.  This
kit deviates from the original slighly because it has a external
volume knob.  The original was not a "stompbox".  It was an
in-line unit that you plugged directly into your guitar.  It had an
on/off toggle switch and the volume was controlled by an
internal trimpot.  I give this one a 4 out of 5 degree of difficulty
because there's an op amp and 2 JFETs that you'll need to
make sure you orientate correctly, but aside from that, this is
still a relatively easy build.
4 out of 5 Degree of difficulty.
