I had an idea about the logo - so I'll butt in and offer it. I thought the three horizontal lines for the E needed just a bit more "spine" to tell people there's an E there. It looked like LOW to me before I read the post. I freehanded the red rectangles in to give you a rough idea of a not-connected vertical line that gives a stronger hint of the E. I assume it would be black, or for that matter, you could color the vertical and change the color on different types of instruments.
Of course, this is worth what it cost you.
