There have been numerous people on this forum who own POD XT's that have told us to remove the fizzy sound from these units by notching filtering 13k. I've just stumbled across another way of getting rid of the nasty fizz while trying to record some guitar solos. I plugged my Digitech Whammy pedal in to use while recording a solo and when I switched it on to the whammy presets without using the pedal it removed the fizz altogether. Straight away my rhythm sounds sounded much more real coming out of my XT Live. I figure this must be down to the Whammy not being having a true bypass? I can't say this seems to have a bad effect on any of the other frequencies either from what I can here. Just thought I'd share my discovery with everyone as we all know it's better to get the best sound to tape/hard drive first rather than EQ later.
