So let me start off by saying that i'm a big fan and user of the sansamp RBI, i just love the way it can turn a j-bass into something that sounds like oil tankers crushing into eachother. Having some money to burn I was thinking of getting the darkglass b7k to maybe replace the RBI but my mind is not made up completely. The demos i've found are pretty much hit or miss. Nolly's demo is obviously great sounding although it sounds a bit more tame then the oil tanker sound i'm always chasing. Some of the clips sound down right like complete garbage (especialy concidering the price of the unit) What say thy ?
