It's been a long journey, and we appreciate your patience along the way. What began in December is now nearly complete, thanks to your support. Our original goal was to deliver all SpectraTone Red mouthpieces by the first week in April. We've now delivered 96% of all orders from backers who completed their surveys. Eight people have not returned a survey, which means we will choose your body variation and set it aside for you, but we cannot ship without your address and rim selection.

That leaves another few backers waiting on rim sizes that are currently at plating. To our surprise, we had an unusually high number of orders for 660 and 614 diameter rims, which had been made in December, but not all were plated. Those should be back in our shop in approximately 10 days or less. If you are waiting on an order for a 614H rim and would like to switch to a different 614 variation to get quicker shipping, please contact us at 303.657.2747.

I have two Titanium mouthpiece bodies remaining, which I will offer to our backers in the form of a complete SpectraTone Red, Yellow, or Blue mouthpiece for $350. If you want one in Stainless Steel, the price is $325. Email me by Wednesday (or order with link below) before they are gone forever. Oh yeah, did I mention all SS and Ti body styles will be retired once inventory is sold out. This is due to the complex production process that is too costly in smaller batches. I made approximately 15% more bodies in SS and Ti than were originally ordered through Backerkit. You can see remaining inventory here.

And finally, I want to announce the debut of standalone LSLT (Laser Sintered Lattice Topology) Mouthpiece Bodies in ALUMINUM. I will be offering these to all SpectraTone/5MM mouthpiece owners for HALF PRICE next week. Again, once these are sold out, they will not be offered again. Your next opportunity for a LSLT solution will come with SpectraTone Green in Autumn. 

Thanks again for your amazing support, feedback, and musicianship!

Jen has been working hard to enter every single order into our system for the past two weeks.
The process has been slower than expected as approximately 35% of our backers have requested some kind of change to their order after we closed the surveys, which has delayed all shipments. For this reason, we will no longer consider any future requests for order changes or additions. We really want to ship your mouthpieces!

Here's what you can expect for the remaining SpectraTone Red shipping schedule.

March 12th - remaining Brass variations with no upgrades
March 26th - all SS variations with no upgrades
April 2nd - all Ti variations with no upgrades
April 9th - all orders with upgrades

We will be offering one final option to purchase a new SpectraTone Red and related accessories at a very nice discount. We're doing this to give your friends, colleagues, and students a chance to get in on the fun.

Be sure to get on our mailing list at Harrelson for the one-day public release on April 1st!

With just a few hours remaining on our campaign, we are excited to announce that production will begin next Monday! It's amazing that we can offer a $400 stainless steel top for only $50. 

This sounds too good to be true and that catch is that today is the last time pricing will be this low.
And imagine what the new trumpets will do for your performance!

Share our Momentum II spinning top project with your friends, family, and colleagues before they're sold out!
