    I simply do not track vocals without the LA-2A. It's simple and efficient, adds that inexplainable 'glue' element to whatever you throw at it. I cannot think of a better vocal chain than a U47 running through a Ruper Neve designed preamp into the LA-2A before the signal hits the converters.… Read More
