+  + Amp Bypass
+
+    It's possible to turn the amp "off" with CC#68 0, but this mutes
+    all sound rather than acting as a bypass.  I don't think the combo
+    amps support signal bypass, but haven't given up yet.
+
+  + Pedal Volume
+
+    I'm not sure why this is needed, since all continuous controllers
+    are directly accessible through CC messages.  Since the FUSE
+    application cannot issue these commands it will be guesswork to
+    figure out the protocol - if it's even supported on the combo
+    amps.

+    If I can figure out how to do this from FUSE I can code it.

+I'm using USBPcap and tshark to snoop communication and plan to
 implement all features accessible from the Fender FUSE application.
 However, some targets listed in the MIDI spec (e.g. amplifier on/off,
 tuner mode) are not controllable from FUSE and it may take some time
