All LSLT Bodies work seamlessly with our 5MM/SpectraTone System
Upgrade your current 5MM/SpectraTone Mouthpiece with improved efficiency and reduced weight in seconds. Our Laser Sintered Lattice Topology bodies are designed to take your playing to the next level. Utilizing the latest Aerospace/Medical Topology software and made with multi-million dollar metal printing technology, you will realize the advantages of cutting edge design and manufacturing. Our LSLT bodies are much more than a conversation piece as your range, endurance, and tone quality tell the story.
Additive Manufacturing is something we've been focused on for many years. This process involves using lasers (or other techniques) to sinter or melt metal or nylon powder into finished products that cannot be manufactured any other way. By designing our latest mouthpiece with high end aerospace lattice topology software, we can now use additive manufacturing to make designs that are more efficient, lighter in weight, and from exotic materials. In short, our Hybrid mouthpieces will easily outperform all previous variations at a lower cost.
Lattice Structure Variations

|
Triangular Lattice is our most popular design exhibiting crisp, clean angles.
|

Octet Lattice is very efficient and our lightest design currently available.

Five Variations explores prototype lattice structures that may eventually become new body designs in the future.
how its made
We begin with high quality 360 Brass from our foundry in Ohio, USA which is precisely cut to tolerances of .001" on our CNC mill/turn centers. Considering the $1M+ cost of laser sintering machines today, we have our additive designs printed for us by a leading aerospace engineering firm. Then we re-machine laser sintered bodies to meet our tight .001" tolerance fit to the brass core machined in-house. Next, we assemble the core, outer sintered metal body, and final nylon contrasting sleeve to create the finished SpectraTone lightweight, high efficiency body. The nylon sleeves are now available in black, blue, green, orange, and red.
All CNC machined components of SpectraTone/5MM mouthpieces are made in our Denver, Colorado shop. To date, we have made over 1800 Rims and over 500 Cup/Throat components specifically for SpectraTone Red as of March, 2024. Final assembly of Nylon, Stainless Steel, and Titanium laser sintered components are also performed in-house.

Testimonials
SpectraTone Red in Brass has been independently reviewed by more than 50 professional trumpet players worldwide in preparation for this launch. We will be releasing review videos throughout December, and we encourage you to provide a video or written review after you have received your new Red mouthpiece.
"Harrelson's artistry and precision design+manufacturing are on full display with RED. The sound is crystal clear with no unwanted noise; sizzling and laser focused, yet still large and commanding enough to fill up the room, with a beautiful, glistening ring on top. The quick response allows you to take advantage of that fat sound by speaking clearly from the very initiation of each note. Every partial feels a mile wide and totally secure, in every register you might need."
- Eric Matthews (Big Band Lead/Commercial Player)
"I thought I would never need another mouthpiece for commercial/lead work after you set me up with the 5MM I use. I was wrong. I will definitely be purchasing this piece regardless when available to add to my stable as I feel the sound output is better than my current piece. Once again, you've worked a miracle and I'm honored you chose me to perform some testing. I've never done this before and it was quite fun! I hope I've provided information that you need. Thank you so much! On a separate note, now it's time to save up for a C trumpet."
- Tim Baird (Educator and Performer)
"Hello Jason!
First off I'd like to say thank you for choosing me to try out and review the new Spectra Tone one Red mouthpiece. I got a chance to play on it for a while and the first thing I noticed was the it had a nice core sound to all around the horn. The V cup shape is not what I'm use to but fell in love with the feel of it.
I was able to access notes clearly that I would never attempt other wise. The lower register is still clear and the high register lights up very well. To be honest it's probably the best mpc I've played on for lead, commercial, and jazz the acclimation period wasn't long at all.
I look forward to receiving my Spectra Tone Red Mouthpiece . I know my playing will go to the next level playing that piece and that horn. I can't wait to receive my Rumors Trumpet."
- Theljon Allen
"First, I usually cannot play "Lead Mouthpieces" as they are too shallow. This mouthpiece plays very easily and I get a great sound from low to high notes without having to adjust anything. Throughout my evening of playing this mouthpiece, I did experience some squirrely high G's at the end of songs. But I attribute that to over blowing and not the mouthpiece itself.
Monday night I had the rare chance to play Lead at my big band rehearsal. By this point I had some time to acclimate to the mouthpiece. I was simply amazed that I played this mouthpiece all rehearsal (2:15 hours long, with no break) and felt great at the end of the rehearsal, still with the ability to play high Gs. This is unusual for me as I do not play lead that much anymore.
What feels really good to me is that the rim/cup seems to hold everything in place perfectly all of the time. I never felt like I was going to bottom out and my sound remained big and fat, while still being able to play softly as needed! My keyboard player (who also plays trumpet) said, You were on fire tonight!
This is the first "Lead" style mouthpiece in many years that feels so good and doesn't back up on me after playing it for some time.
Thanks Jason!"
- Gary Greenfelder (GG Orchestra - www.ggmusicent.com)
"I loved the way the mouthpiece sounded! The upper register has a sort of spark, and the overall blowing feels way easier. I was shocked by the difference in feel when playing. I have a jazz audition coming up here at OU, so I’m going to test it out during the audition. I definitely felt like I could play those high E’s more consistently with this mouthpiece, and I could get more volume out of all registers on it as well. I think I might get one of these mouthpieces when they release!
I’m going to ask my studio peeps to send their feedback as well. Overall, the mouthpiece is amazing and I wish I could get one sooner. The price is high, but the quality is definitely worth the money."
-Angel Lira (University Of Oklahoma Trumpet Studio)
"Really impressed with the even blow from top to bottom, plenty of sizzle and projection up high, and great intonation. If I were to work with you in building something like this, I’d be particularly interested in dialing in rim size and cup depth just a bit more. I opted not to try to dig in any higher as it felt a bit shallow for me.
Good work on this, I’m glad I could be part of the test run with you!"
