Own a one of a kind high efficiency prototype months before the G5 release!
We've finished our testing on the first two G5 Summit prototypes and need to get these into the hands of trumpet players right away to start gathering feedback. This is your opportunity to own a piece of history while taking your playing to the next level. The G5 series is scheduled to be released in approximately 4 months, so you'll be the first to experience all the benefits of many years of research and innovation.
To qualify for this prototype trumpet purchase, we ask that you agree to a brief phone call and provide written feedback detailing your experience with your new G5 prototype trumpet after 30 days. Your feedback will help us shape the future of our G5 design and production for years to come.

Venturi Gap Receiver - The VGR is a pillar of our Variable Performance System and the ultimate solution offering fully adjustable flexibility, slotting, and air flow. Fine tune your setup to match impedance between your oral cavity, mouthpiece, and instrument to produce maximum resonance. Works with all mouthpieces. You will learn to use this very capable system in just a few minutes.
SWE Leadpipe - SWE Leadpipes are the most versatile and efficient solution available today. Our 3rd generation SWE leadpipe is CNC machined up to 100% thicker than previous generations. SWE (Standing Wave Efficiency) Technology sets Harrelson solutions apart from all other brand manufacturers by preventing sound wave energy from converting into vibration except at the areas of resonance.
Topology Optimized Bracing - Improved efficiency through design includes bell coupler, leadpipe to bell bracing around valve casing, first slide to bell brace, and 3rd slide stop brace. This new bracing is up to half the weight when compared to our previously CNC machined designs and offers more than double the surface area contact. This results in further increasing SWE while improving stability in the upper register, overall response, and stretching the dynamic range beyond that of our 3rd generation Summit.
Topology Optimized One-piece Tuning Slide - Greatly improved efficiency within the tuning slide providing more stability in the upper register through a new production process and topology optimization specifically engineered to resist anti-nodal high pressure zones on every partial through double high E. This means you can play in the upper register without working harder. Simply set up the appropriate frequency with your embouchure matched to the necessary air pressure and velocity to play any note at any dynamic level, much like playing a piano.
Top & Bottom Caps - Special limited edition top and bottom caps designed with SWE Technology principles in 5 variations from light to medium in weight.
High Efficiency Valve Stems (HEVS) - Improve efficiency and stability while avoiding damaging aluminum corrosion. (upgrade option)
