I've found that certain sounds were likely incomplete, and Marcus or someone in the past filled in some missing notes from the next closest thing they had at the time? Also, those celeste sounds are really useful for processing through guitar pedals like over drive, fuzz, and distortion, etc. and can produce some very realistic electric guitar solo action! 🥰I particularly like using a "tone bender" style fuzz pedal. (clones/emulations, I don't have an original)
