I recently changed my pickups in my jackson rr5 over to emg 81, 85 set. Well im getting almost zero harmonics. That a huge problem for me because im really big on squeeling. What do you guys think i should do everything is hooked up right and everythings good but no harmonics should i switch the pickups over to dimarzios(sorry if i spelled that wrong)

Thanks guys for all your help
Could be by anychance does anyone know the pickup to string ratio or the string to fretboard ratio
