I have bouht my VLA a couple of mounth ago from ZZounds
ART Pro VLAII 2-Channel Compressor
works real fine with bass and acoustic. Lenede it to one guy to record Sax. Also was quite fine.
I did not have problems with noise.
The problem with VLA it is has Opto compression not a VCA so it's not very good for drums. For drums DBX is a must have I vould say. I actually think DBX should have called their models "Drum Compressors"
