The only effect I currently have is a Boss chorus and haven't used it in church but am considering it or some other effect. Without considering compression (this is in my rig) I was wondering what the most common or useful effect would be in a church worship setting? This can be for either prayerful, quite times or full-out gospel jamming. I recently received an EBS octaver but returned it as I see very little use for $180 of pedal. Thanks in advance.
