The new G5 Stainless Steel Series Summit is more advanced than any other trumpet available on planet earth. Incorporating lattice topology optimization technology, the G5 has been designed to increase efficiency and strength while reducing weight. We have integrated the same design tools as NASA and advanced technology manufacturers in the Medical, F1 Racing, EV, and Aerospace industries.
Introducing the 5th generation Summit Trumpet - the most resonant and lightweight design ever!

We will discuss your playing preferences to build the trumpet of your dreams
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.
5th Generation SWE Leadpipe with integral bracing - SWE Leadpipes are the most versatile and efficient solution available today. 3D printed from Stainless Steel. 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.
Leadpipe and Bell Angle - You may choose from our standard straight leadpipe or 5, 10, 20, and 30-degree angles. And your bell can be tilted up by 10 degrees to accommodate downstream playing styles.

Topology Optimization - Improved efficiency through design includes tuning slide, bell crook, bell coupler, leadpipe to bell bracing around valve casing, first slide to bell brace, and 3rd slide stop brace. 3D printed from solid Stainless Steel, 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 4th generation Summit.

Topology Optimized One-piece MBS Tuning Slide & Bell Crook - Multi-Bore-Shape technology (MBS) improves impedance ratios to make the upper register sing with very little effort. This approach to design maintains overall volume and air flow while morphing into several shapes that achieve better impedance tuning. All MBS components are metal printed from 316 stainless steel typically used for marine and food processing applications. Greatly improved efficiency provides 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. Our new G5 Light tuning slide is under 4 ounces, which is a 50% weight savings over 3rd generation designs. And our new matching Bell Crook weight has been reduced even more!
New 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) (upgrade option) - Improve efficiency and stability while avoiding damaging aluminum corrosion.

What's the difference between our G4 and G5 models?
Our new G5 Summit model is lighter, more resonant, and and slightly less efficient than our G4 variation.
Choose the G4 for the overall easiest playing experience in all registers and at all dynamic levels.
And choose the G5 if weight savings and vibrancy are your priority.
