Todd, Cameron and the other technicians know their amps well enough to create the sound you hear in your head: yes; they listen that carefully and are that knowledgable. I bring my amps (I have many old tube amps of a variety of vintages and makes) and I live in Toronto, Ontario. Se have tube amp repair people in Ontario, but no one who listens and tweaks like these fellows. I am lucky enough to own a property in Nashville and one of the things that makes that southern home so valuable to me is having ready access to Nashville Amplifier Service. Them, and of course, my sweetheart who lives in Nashville fulltime--as much as a successful, world-clas, globe-hopping recording artist ever lives at home....
