I dislike EMG's altogether, so take my opinion with a grain of salt. I believe most people prefer hz simply for cost purposes and then teach their mind to like them. Hz is NOT what should come to mind when you think EMG tone. However, there are people (myself included) who simply dislike active electronics. Now, I dislike the tone of all EMG's. But simply for the pure fact that hz is passive and I prefer passive electronics, they are preferred by me.
Can you hear the waves? Crashing in the dissonance?
