Great product, well built

I really like the Miller machine it's makes playing a triangle hit doable when your hands are occupied with other percussion implements.

Thank you for the nice review Joseph! Billy

Great product that is about to make my life easier

I bought the Miller Machine for an upcoming run of Evita. I’m looking forward to putting it to work. So far it is exactly what I needed. Thanks Billy!!!

Hi John, thank you for the review! Have fun with Evita. Billy

George M.
First time application of Miller Triangle Machine

Overall, the triangle machine worked great. Used recently to play a local production of the musical Chicago. It would not have been possible to play correctly without the Miller Machine. Set up was easy and straight forward too. Well-made device, though I would have been just as happy with a lower cost less polished version if equally functional.

Thank you George! And thanks for your feedback, that's very helpful. Billy

Andrew W.
Miller Machine FOR THE WIN!

The Miller Machine is ESSENTIAL! I found out I needed a second triangle arm a few days before tech rehearsal and Billy offered to ship me one super quickly in order to fill my needs. There isn’t any better customer service than Billy and The Miller Machine! I will ALWAYS have one (or 5) in my setup!

Andrew, Thank you!!! I'm glad I was able to help you get ready for the show. Billy
