Jim Holland, Musician/Engineer/Producer

“The M63 makes ALL microphones sound great. My U47 has never sounded so U47-ish! It is also a fantastic tube DI. It shines on bass guitar and keyboards as it can be overdriven subtly or to an extreme or not at all.  It’s crystal clear with sharp transient response and reach for miles, and it can also be a dirty beast on kick drums or a sweet fuzz pedal on guitars or anywhere in between the way it adds those beautiful even harmonics when overdriven.”
