Jim Liban says:
"The Astatic I got from Dennis is my favorite harp mic right now. The tone is fat, deep, and fantastic! He knows his mics, inside and out."

Rick Estrin says:
"Dennis is not only a meticulous, ultra-experienced mic technician, but he can also play his ass off! That gives him the ability to assess and choose an element that will be ideal for your specific needs."

Student Testimonial
“It has been my pleasure to have become one of Dennis' students…from the time we had our first 'in person' session, to our current setup of doing the online sessions. I have become a full time tounge-blocker thanks to him! Also, my ears have been hearing & listening for things I never would have picked up on my own. I must say, I am a much better & more comfortable player, since I started sessions with Dennis!”

“Dennis Gruenling's online lessons are as good as any face to face lessons. The setting is just as intimate - it becomes just you and Dennis. I think his lessons are better than anything else one might find...Dennis is one of the premier contemporary players of the day, and yet teaches you as if he cares more about your progress than anything else."

“I have taken two 'semesters' of lessons with Dennis. As an intermediate player when I began, Dennis has definitely helped me achieve the next level in my playing. Dennis’ approach to music theory has helped my understanding of music tremendously. I now consider myself a musician, not just a harp player. Even long distance, these lessons are a great value for the money!”

"Dennis is the perfect teacher – he points you in the correct direction when you need help, he makes you feel comfortable, and he helps if you are feeling frustrated. I have now gotten to the level that I am in my own blues band and I never could have made it to this point without Dennis.”
