IMHO its a must have Comp, there are 100's of comps and tons of them try to do what this simple beast has done from the start and at $49 it's a steel for your mixing tool box. I only have bought two compressors from the shop the REA2 and the OzoneMaximizer and got of them on sale. there are a two more I will be getting when they go on sale and I will be set. I love the comps in the mixer they really are great for control and with the REA2 I can easily give things color that the mixer cant. Easy as that.
