Containing meticulous recordings of both a Yamaha Recording Custom and a Birch Custom Absolute kit, BFD Heavy includes 3 kicks, 9 toms and a bonus reduced-detail Yamaha Jimmy Chamberlin steel-shell snare (taken from BFD Signature Snares Vol.2). Kicks include wood and felt beater versions while the bonus snare and 5 of the included toms are provided in stick and mallet versions. BFD Heavy's expressive articulations include rim shots and rim clicks on the birch toms and half-edge samples on the bonus snare.

BFD Heavy is recorded in similar studio conditions as BFD Percussion, other FXpansion Yamaha-based expansions such as BFD Maple Custom Absolute and the Mapleworks kits in BFD3.
