I returned this pedal after much frustration in trying to find useable tones. I bought it based on great internet reviews, but I found the pedal to be almost useless. I play Jackson guitars through a Maeshall JCM2000. The pedal has many dfferent settings i.e. 3rds 4ths 7ths, etc...The tones are very artificial sounding and sound very brittle almost like somebody hitting a steel drum behind the note you are playing...The only useful tone I found was the setting for 1 octave lower. The Digitech Whammy Harmonizer is only slightly better. A decent harmonizer is $500 plus.
