The new G4 Series Summit is more advanced than any other trumpet available on planet earth. Incorporating lattice topology optimization technology, the G4 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.

The greatest improvements to the 4th generation Summit include a one-piece 3d printed stainless steel leadpipe and tuning slide that will never rot or dent while reducing weight and improving response, efficiency, and stability. I have further reduced the weight to efficiency ratio by casting new topology optimized bracing and finger rings from Copper and Red Brass. Experience unbelievable projection at any dynamic level with less effort and weight than any previous Harrelson instrument.

Simple Strut Prototype shown, final G4 Summit Leadpipe is in Stainless Steel
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.
4th Generation SWE Leadpipe - SWE Leadpipes are the most versatile and efficient solution available today. 3D printed from solid 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.
Topology Optimized Bracing - Improved efficiency through design includes your choice of Copper or Red Brass 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 & Bell Crook - Greatly improved efficiency within the 3D printed solid Stainless Steel tuning slide (and optional matching bell crook) 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. Our new G4 Simple Strut 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 Summit 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.
