The Official Home of the HARMONIC CONVERGER (HC)

Thanks for visiting my website. I am Hadley Hockensmith, lifetime pro musician and electronics designer. I became interested in electronics at 7 years of age, and started playing guitar at 12. My musical career is ongoing, and I currently play guitar full time for Neil Diamond, and am an active songwriter and LA studio player as well.
Over the years, I have been blessed with the privilege to record and/or perform with many great artists: Ray Charles, Michael McDonald, America, Jeff Beck, Glen Campbell, David Gates & Bread, Elton John, Leon Russell, the Righteous Brothers, Billy Preston, Johnny Rivers, Michael Omartian, Gordon Lightfoot, Maria Muldaur, Conway Twitty, Larry Carlton, Andrae Crouch, Keith Green, Phil Keaggy, Koinonia and many others). I have always modified my own equipment, and have done mods for many prominent LA musicians as well. The purpose of this website is to provide a place where I can post the latest up-to-date info regarding the sonic enhancement device I design and build, known as the Harmonic Converger (HC).

The info posted here supersedes ALL other HC threads, posts, and reviews found anywhere else on the web!
Please do not be confused by conflicting descriptions or older reviews of the HC, as the design has been updated many, many times! There is much conjecture and misinformation on the web regarding the HC, so THIS is THE place for current, trustworthy info, as well as Please feel free to explore all the pages of this site, as there is a lot of important information about what the Harmonic Converger does sonically to enhance the tone of your modeler or preamp, as well as hookup recommendations and interfacing tips.

The story of the Harmonic Converger - "Necessity is the Mother of Invention"
I was very excited when digital modeling first appeared on the horizon. Like many others, I was looking forward to all the convenience & flexibility being offered, but was soon disappointed when I heard the typical lack of urgency & presence coupled with an abundance of ‘insect attracting’ fizz, which sounded totally disconnected from the body of the tone. To me, it seemed like an "evil miracle" that the tone could simultaneously lose the presence while exaggerating the fizz! At first I got depressed, but then I got mad and became consumed with the quest to regain what that had apparently been lost - the sound and feel of a focused, cohesive, natural tube amp response which was truly believable in a mix, and without all the tell-tale fizz. 
Like a good tube amp, the HC imparts its own character or timbre to the tone, which makes modelers sound substantially more believable and amp-like while still preserving the unique "signature" of your processor's Amp/Cab models.
