HH refers to the production of the cymbal: hand hammered. Though the cymbals are hand hammered, you can find them in both natural and brilliant finishes. Natural finishes are left after the lathing process, with the tonal grooves left unpolished after production. These cymbals tend to focus more on bite and tone than do their brilliant finished brothers. Brilliant finished cymbals are put through a high-pressure, high-heat process after production, that leaves your cymbal sounding as smooth and glassy as it looks.
HH cymbals made today have been nicknamed “Vintage Dark,” since the series is the oldest, making it vintage, and the sound quality, which is dark. These are the most traditional of the HH lines by Sabian, which can be compared to HHX cymbals, known as “Modern Dark.”
