Designed for all ages & skill levels, SpectraTone Trumpet Mouthpieces offer a full range of tone colors, unmatched comfort, and control over variables.  With the full SpectraTone series, we have created the ultimate mouthpiece suitable for every performance situation and 100% compatible with all brand trumpets.

SpectraTone will improve your performance from day one. You can choose from a wide range of diameters and three rim profiles to maximize comfort, range, and endurance. The fully modular design allows you to adjust tonal color and upgrade any parameter as you progress over time. This is especially helpful for students, comeback players, and professionals who will experience growth, both physically and musically, in the coming years. 

 

SpectraTone mouthpieces are currently available in Red, Yellow, and Blue. This Backerkit campaign allows you to experience one or all three variations. Red is bold and brilliant with rich overtones. Yellow is both vibrant and warm simultaneously. And Blue is warm, dark, and mature. All three variations are suitable for performing in Classical, Jazz, and Commercial settings depending on the tone color required.

Finding the right mouthpiece is the key to experiencing a major performance breakthrough. Comfort and dental fit are more important than any other factors. SpectraTone mouthpieces were designed with the input of thousands of trumpet players who have shared their challenges with us over the past twenty-five years.

Six variations in 14 Diameters - .550" (14mm) to .680" (17.3mm)

H-series Rim - round inner contour designed for ultimate flexibility
Standard - standard contour, average inner and outer radii

Wide - standard inner contour with wider outside contour

Semi-flat - slightly flat version of "Wide"
Flat - just like it sounds, more surface area on your lips
Very Flat - maximum surface area for less mouthpiece pressure

Players with perfectly straight teeth prefer a different rim contour than those with braces or crooked teeth. And the diameter you've been playing on may be too large or small, which may limit your tone quality and range. The SpectraTone mouthpiece design takes these factors into account to help you make real progress. 

The following may be asked in the survey after the SpectraTone campaign has ended in late December. Your answers will reveal the best rim diameter and contour to fit your individual needs, or you may choose from any of our variations.

1) Which mouthpiece(s) are you currently playing? 

2) You will choose a rim diameter based on our Rim comparison chart.

3) If you need assistance, we will ask you to describe your dental structure to determine high point position.

The high point is a key piece of information that will determine the rim contour. The theoretical high point is a ridge formed by one or more crooked teeth that your mouthpiece may rest upon. Players with one or more high points often find round contour rims to be a suitable choice as blood flow is increased with this type of setup. 

Players with near perfectly straight teeth will usually have difficulty with a round rim contour as this may cut off the blood supply to the vibrating portion of the lips. These players may experience greater success using a wide or semi-flat rim contour. And braces create other challenges that may require any of these contours to alleviate indentation of the lips and increase blood flow. 

All SpectraTone mouthpieces may be upgraded and adjusted over time by purchasing modular components in the future. We have assisted thousands of clients in their mouthpiece journeys utilizing our versatile system of Rim, Cup, Throat, and Backbore (cornet & trumpet) options. In fact, we have the largest library of variations ever made so it's easy to find what you need, when you need it. 

SpectraTone allows you to adjust the tonal color in a matter of seconds. Need to open up your sound? No problem. Control air flow, flexibility, slotting, tone color, attack, and more with easy affordable upgrades.

Here's a quick rundown of what to expect with this Backerkit campaign.

1) You will make a pledge for a reward, which is technically different than buying a product. In essence, you are helping us reach our monetary goal to offer discounted rewards to our backers. Your pledge amount will be charged to your credit card when the campaign ends. 

2) You will receive a survey through your Backerkit account after the campaign has ended. Once you respond to the survey questions, we will prepare your reward and ship it to you. 

3) We will support you with amazing customer service for as long as you own your SpectraTone mouthpiece(s).

"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!

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.

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.
