1. Footswitches
These two Footswitches are used to select presets, access the Tuner, or bypass the RP150.  The 
Footswitch on the right will select the next preset up, and the Footswitch on the left will select 
the next preset down.  Pressing both Footswitches together will bypass the currently selected 
preset.  Pressing and holding both Footswitches for 2 seconds will access the Tuner.  Press either 
Footswitch to exit Bypass or Tuner mode.
