The Triangle Machine Plus is the result of a collaboration between Billy Miller, and Neil Grover of Grover Pro Percussion.

Machined from solid 6061 aluminum and finished in a natural aluminum finish.

Designed for modern percussion setups, the Triangle Machine Plus lets you play the triangle accurately and consistently without sacrificing sound or control. Set it and forget it, reliable performance night after night.

Beater angle adjusts from 90° for a focused, direct sound, ideal for pit work, to 135° for a wider spread of overtones suited to orchestral and contemporary settings.

Beater position slides side to side, allowing precise placement for any setup.

Beater Options

  • Brass: Warm and mellow. Ideal for softer musical settings.
  • Stainless: Bright, clean, and consistent. The best all-around choice.
  • Steel: Sharp and focused. Maximum projection in louder environments.

Arm Selection

  • Regular Arm: For triangles up to 7".
  • Plus Arm: For triangles 8" and larger.

Designed and built by Broadway drummer/percussionist Billy Miller.

The Miller Machine system is fully modular, mix and match bodies and arms to build your ideal performance setup.

Note: A Triangle Arm is included with every Triangle Machine Plus, no need to order it separately.

More information below.

Not included: mount, or triangle.

90 to 135

Beater angle adjusts from 90 degrees to 135 degrees.

90 degrees is great for a more focused sound, ideal for pit work.

135 degrees gives you a nice spread of overtones, great for orchestral, and contemporary settings.

Side to Side

Beater slides, side to side, to find the optimal position for your particular setup.

Most helpful when the Machine is set to 135 degrees.

Suspension Mount

"I really like this update.

There’s a safety loop just in case you have a failure mid-show and the increased stability of the hang lets your triangle stay still for manual and fast playing.

Solid improvements on an already great product."

"Damn Smart"

Just got the new machine. Thanks for incorporating the beater change I had in the back of my head, and the tilt function is damn smart.

None of the shows I'm doing this season call for a machine (Wicked and Beautiful) but I'm super glad to have it in my hands!

In the Wild

Highly-rated percussion tool praised for enabling hands-free triangle playing during complex musical performances. Customers said it's "a game changer" with "amazing quality, response and versatility." The Plus model features adjustable beater angles (90°-135°) for tonal variety. One concern: beater angle may shift during performance. Excellent customer service noted.

Indispensable Tool for Percussionists!

I just received my Miller Machine Plus a few weeks ago and I already don't know how I could live without it. I even added the Horizontal Mount and the Finger Cymbal Mount to my original setup. Brilliant ideas! And fast personal service from Billy!

Thanks Steve! Glad we worked out the shipping issue. Enjoy your new Machine! And thanks for sending the photos. Billy

Triangle Machine Plus

This is my third Miller Machine and I'm so impressed with all of the improvements: the 90°-135° tilt, safety cable, sliding beater position, build quality, etc. I didn't think the original Miller Machines were in need of improvement because they were already excellent...but, wow, you're probably going to need one of these ASAP. My first machine went on the North American tour of Hairspray (226 performances) and I never had a single problem with it, I never had to change the plastic ties! I've used it and the finger cymbal machine hundreds of times - they just make life as a percussionist so much more convenient and consistent - perfect tone every time.

Thank you Troy! And glad the Machines have held up so well for you. Billy

Should have bought one a long time ago!

Used my new Miller Triangle Machine Plus for two different show productions in the first few weeks of owning it, and I already count it as one of the best investments I've made in equipment. A well thought-out, well engineered, and well-made product that is now an essential part of my gear kit. Highly recommended!!!

Thank you for this wonderful review! Glad you're getting lots of good use out of it already :) Billy

Amazing innovation

Extremely well constructed and thoughtful designs! The Miller Machine Plus is easily mountable and gives a free range of angle for the beater to strike. The level of customization with angle and beating area is fantastic. The beater upgrades really give excellent response and sensitivity with an extremely natural feeling rebound.

I also couldn’t be happier with the upgrades for my first generation Miller a machine!

Thank you for the wonderful review Kyle. I'm glad the upgrades are working out and you're enjoying your new Plus Machine! Billy Awesome photo too ;)

Amazing investment

I purchased the Miller Machine to help with my rack players for indoor have a more ergonomic setup. The students were overjoyed to see it in and immediately made their playing experience easier. I will be recommending this brand to anyone who asks about finding ways to make their setups easier.

Thank you for this wonderful review Dr. Jones, I appreciate you taking the time to do this! I'm glad your students like it. Billy

Thank you for the awesome review Chris! Enjoy your Machine. Billy

Hi Billy

Hi Billy,

I’ve often used the normal model in the performance of musical works for a long time.

The plus model that changes the angle of the beater this time is very good, but I was worried that the angle of the beater would go down and lower if I kept hitting during the performance.

If the place where the angle is adjusted is a gear,
the angle does not change during the performance, I think it will be even better.
Thanks,
Yoshiki

Hi Yoshiki,
Thanks for your feedback! I received your follow-up email, and I also wanted to make a short YouTube video (link below) for you to help ensure everything is set up correctly.
The Plus Machine shouldn't be slipping, so the video shows the correct assembly and adjustment to help make sure everything is locked into position properly.
If you have any other questions or if it's still slipping after watching the video, just let me know and I'll be happy to help.
Thank you!
Billy

Billy Miller makes fantastic products

This body is solid and versatile. Everything Billy does is with the utmost care and his customer service is truly amazing. I use the triangle machine, finger cymbal/crotale machine and cowbell/woodblock machine in my setups very frequently and do t know what I’d do without them. The fact these great products are made by such a fantastic guy is just a bonus!

Thank you so much Liz! Grateful for your continued support and loyalty. Billy

Triangle Reintegration!

I used my new Miller Triangle Machine for a high school performance of "In the Heights". I played hits I would have had to leave out if I had to pick up a beater and hold the triangle still. Such a great addition to my percussion kit!

Love this, thank you Linda! Glad it’s working so well for you. Billy

Should have bought The Miller Machine sooner!

What can I say! You're not a real pit percussionist without this gadget! Amazing quality, response and versatility. I can't believe I've gone all these years without it. Delivery was also quick and everything arrived in pristine condition. Thank you!

Hi Jesus, thank you for your wonderful review of the Plus Machine! Keep in touch, Billy

The Triangle Machine Plus has been a solid addition to my setup. It’s made transitions in the pit much smoother, and I really appreciate how adjustable it is—you can easily find the sweet spot for sound and technique. Whether I’m playing with a stick or hand, it’s reliable and easy to control. It’s a well-designed tool that fits seamlessly into busy setups. Definitely a 5-star product.

New Machine & Beaters for Nat’l Tour

Sal here, writing in from the current Addams Family National Tour.

I decided to upgrade to the new Horizontal Mount and Machine Plus body. Until Billy comes up with something else, I think this is the apex of Miller Machines. Not that there’s anything wrong with the previous models. This is my third machine now, and I will still be using the others.

For this gig, I needed the flexibility that the horizontal mount provided — giving the potential to hang two triangles, a finger cymbal, and hold beaters. That paired with the Machine Plus body makes this a killer combo and a must have for any professional.

I’ve also been experimenting with the new beaters. I really love the sounds I’ve been getting out of them so far. They make my Black Swamp triangle sing with beautiful overtones, and there’s enough variety in the set to cover many different situations. Definitely grab some of these!

Thank you Sal!!! Have a great time on tour! Billy
