For over a quarter century, Pearl's Session Series has yielded some of the most harmonically vibrant recorded drum tones ever captured in the studio environment. Returning with a custom upgrade from their Masterworks spectrum, modern Session Studio Select drums shift to a thin, 5.4 mm EvenPly-Six combination of Masters-grade birch and African mahogany. The result is a blend of pre-EQ'd clarity and warmth with the added controlled punch of Pearl's fresh 60-degree bearing edge.
