The Triangle Machine + (Plus) comes from a collaboration between Billy Miller, and Neil Grover of Grover Pro Percussion.

Beater angle adjusts from 90 degrees, for a focused sound (ideal for pit work) to 135 degrees, for creating a nice spread of overtones (great for orchestral and contemporary settings).

The position of the beater slides, side to side, to find the optimal beater balance for your particular setup.

Includes the new custom made 5/16" Solid-Body Brass Beater. Length, weight, and balance (fulcrum) all optimized to get a great sound from your triangle.

90 to 135

90° is great for a more focused sound - ideal for pit work.

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

Side to Side

The solid-body brass beater slides, side to side, to find the optimal position for your particular setup.

Most helpful when the Machine is set to 135 degrees.

New 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!

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
