The Harrelson SWE Mod Kit is the perfect upgrade to your existing trumpet. Available in several finishes, over 200 inlays, and unlimited custom engraving options. These are the perfect compliment to our HEVS (High Efficiency Valve Stems).

Now available for Baritone and Tuba by special request.

how does swe work?

Standing Wave Efficiency (SWE) Technology is a physics-based design method that preserves energy in the sound wave as it travels through a tube or instrument. In a traditional trumpet, energy in the standing wave is transferred into vibration of the resonating wall at the anti-nodes as it travels through the trumpet. The further the wave travels, the more your sound wave energy is transferred into vibration. To make things more complicated, the higher the note on the trumpet the greater number of nodes and anti-nodes. These nodal points vibrate the tubing wall and braces, robbing even more energy from the wave.  A common side-effect of nodal points involves Excessive Vibration Interference (EVI) between fixed points (trumpet braces) separated by vibration-prone material (thin and/or stiff tubing).

EVI is present on all traditional trumpets especially along the leadpipe and bell, which results in interference with the original sound wave. The EVI effect becomes more noticeable in the upper register of any brass instrument. This is due to the greater number of anti-nodes and nearly proportional number of spans measuring EVI. Difficulty in the upper registers of the trumpet is mostly due to excessive vibration and the EVI effect. Reduce the EVI with SWE technology and the upper register will respond and sound much like the low and mid-registers.

High efficiency Harrelson Trumpets retain sound quality and character throughout all four octaves by preserving energy in the sound wave. It is possible to double and triple tongue three octaves on the VPS Summit and Muse series when MBR has been achieved.
