I was just reading the new book Recording the Beatles and got more insight into why their records sound so awesome. They really were a studio band!! I knew they had top producers and engineers, but learning about their use of the Fairchild 660 limiter and the EMI RS127 Presence Box was very enlightening. So I am thinking given this what live tools i. e. pedals, could do similar magic for live work? I am thinking on the top of my head perhaps the TWA Triskellion as it can get some neat midrange tones, or EP Booster??? What I am looking for is not as much an "effect" as say a tone enhancer for lack of a better definition. Any thoughts on this?
