The Progressive Foundry SDX was recorded at the famous Sing Sing Recording Studios in Melbourne, Australia, engineer / producer Forrester Savell. He chose Sing Sing Recording Studio for this project. For more than 35 years of work, the studio has assembled a huge selection of top-class microphones and rare hanging devices. Combined with solid wood walls in its perfectly balanced Room A, Sing Sing proves time and time again that it is the ideal medium for wide, transparent drum recordings. The drums, which were selected by Steve Judd himself of Karnivool, were assembled in all four corners of Australia and represent a huge collection of the best in rare, vintage and modern styles.
