Sound Pure's Take

If you haven't checked out our video content on the 501 pre, that would be a great place to start. This pre is better off being heard than talked about. It just doesn't get more lush and creamy than the electrodyne in the world of solid state preamps. If you're concerned about too many competing tube colors in your signal path, but still want a richness and fullness that you'd expect from a tube pre, stop looking and call us to demo one of these preamps today.

The electrodyne IS capable of cleaning up and being more forward and focused, so it's no one trick pony like so many tube pre's that are out there, but seriously - you get this pre for vocals and instrument tracks that you want to push back in time to an era when everything sounded like a big round hug. That's the magic of this box, and I just count myself lucky that it can also give me a more forward sound when I need it.
