After David's tutorials, I started getting paid clients. I took 2 years of audio school at a community college and then 4 years at OSU doing recording engineering. I learned more from 1 of David's courses than all 6 years combined!
I've spent time at Full Sail, working along side of other engineers, and countless hours in multi-million dollar rooms. But my biggest wins were when I watched you mix. Something about your workflow just made it all click together.
I've bought 3 or 4 DG tutorials and they are all extremely informative. I highly recommend anything he puts out. Don't buy another plugin that won't help you, and spend your money on what matters most in mixing - your knowledge.
