Here is a bass mode patch I did for the Pearl Jam song "Better Man".
EXP heel down is normal pickup bass
EXP toward toe end fades in the organ tone for the first verse
Press the EXP pedal switch to EXP ON and the fun begins,
initially for the feedback guitar intro before the clean guitar main song starts
also with PCM tone hold while the CTL pedal is held on (for feedback hold on every second note).
Also added pitch bend for a bit experimental fun too. (if you want to get a bit carried away).
