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 & Bell Crook - 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. The topology optimized bell crook option will debut in November of 2025. Available to match the material and design of your chosen tuning slide only.
G4 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.
