HI Remy,
No there are not any rotor speeds that are more ‘reggae’ than any others. The speed of the rotors, on a real leslie depends on the WEIGHT of the top horn and lower rotor. The rotor, is made of plywood in most cases and larger, therefore heavier so it speeds up and slows down slower than the very light weight horn on the top. So those speeds are rather random. Sometimes the digital settings have the lower rotor speeding up too fast, but in my opinion it’s not that worth stressing about. Hope that helps!
