Essential is the key word here. drum kits with kicks, snares, toms, roto-toms, and a myriad of hi-impact processed drums, plus cymbals (featuring an excellent hi-hat) and industrial dance sounds. loads of percussion too. The diversity of bongo drums is particularly outstanding. lots of tambourines, maracas, shakers,congas, cowbells, timbales, and all the others youÆd expect are found here. the variety is impressive and the sounds are well done.
