Always 1st Class, and know exception here. Dub vibes with amazing sonics, but know surprise there for me as production values are so high. 100% authentic from Dubmatix. Having worked on a Album together I am duty bound to say these packs are on a different level. This packs pulls you in to the origins of Dub, but always future proof..... From heavy pulsating B-lines, to Skanks, Drums are so good. The instrumentation is excellent, with serious percussion elements. High Tower selection all over this. This is the perfect solution to your Dub Productions. Number One Killer......
