HI, I just got my HD500 last week... its a superb unit and I'm really enjoying using it... But I can't do volume swell with the on-board exspression pedal... At toe possition it sounds full but when I slowly decrease it the volume suddenly ends at only the mid range possition of the pedal travel... Can anyone assist me how to rid of this problem??? I already calibrate the pedal but that doesn't help... And also the EQ's in HD 500 are way too complicated to use... Its doesn't have the full visual of the EQ paramiters as in POD X3 LIVE (my previous unit), so this makes it tough to control the balancing... Please help me guys... :-)
