Does anyone have any documentation on the pre-loaded effects pedal within the POD HD500X and how they cross-reference to the manufacturers pedals? IE, Pages 7-1 thru 7-11 within the Advanced Guide indicate the various effects pedals. Page 7-2 lists the distortion pedals. The "Tube Drive" model cross-references to which manufacturer? Has there been or has anyone developed any type of "cross-reference" chart for all of the effects pedals within the POD HD500X system?
