Rudd also In Early Days of acdc After Leaving Buster Brown Used A Mixture of Slingerland & Ludwig before fully Using Sonor Drums I Belive Rudd breifly Used Sonors Acyrlic Kits but he didn't like the sound the and switched back to wood shells for Sonor
I had a Slingerland Avante set that I purchased used back in 2011. I loved the set, but the bass drum had giant cracks under the tom mounts and it was affecting the sound, so I sold them. I am guessing that the set was used without the front bass drum head, and the weight of the toms damaged the bass drum.
I would love to find another one in better condition.
