ABOUT US:

Don Bradley
(holder of over 38 U.S. and foreign patents in Electrical Engineering) is a prolific inventor and leading pioneer in the Test and Measurement Industry.  He holds the position of Senior Fellow at a leading Test and Measurement company and is warmly recognized around the campus as "The Wizard".  Don also has extensive experience in musical electronics gained while coming of age in the 60’s, and has been a guitar player since his teens.  Don enjoys wowing his neighbors and co-workers with his high-powered Tesla coil, and taking time off to travel to warm, tropical places.

Matt Agresta is the sales side of Bradley labs.  Matt has an extensive background in Sales Operations and Management.  A guitar player for 25 years, he caught the bug and never let it die.  He is a die-hard tone chaser and has been lucky enough to work with Don watching him bring the Iron Horse to life.  In his spare time, he has the world's most understanding wife and kids, and plays in a local band called The Newcastle Brothers.  The Iron Horse will be getting played a lot this summer!

 

Together, Don and Matt are an unlikely pair.  Matt still can’t get Don excited about the first Van Halen album, and Don can’t get Matt all hot and bothered about the “Ventures”.  They do agree on one thing:  Building tube amplifiers that will blow you off the planet!

Here is the birth of Bradley Labs.  Below is a 1959 Newspaper clip of Don (12 years old) demonstrating his invention at the local science fair.




Fun at Bradley Labs:  Nothing brings more joy to a party than a Tesla coil!



"Dude, can you build me a guitar amp?"  Don explaining to Matt the intricacies of his Tesla Coil on June 13 2009.   After this conversation, Don designed the circuit.  He was stuck on a name until a suggestion from his old High School buddy Ben Perry.  On June 20th 2009, Don officially named his design "The Iron Horse".





Chronology and Evolution of the Iron Horse:

Jan 9, 2010

 

Happy new year everyone!  We've been busy over the past few months getting the site together to promote the Iron Horse and doing some clandestine demos.  So far, the reaction from players has been phenomenal.  Just this week, we took it to two local music stores here in the bay area for an audition.

 

In both instances, we saw smiles, excitement, and utter amazement.  At one of the stores, the Horse had to compete against a full line of top shelf Boutique amps:  65 Amps, Dr. Z, Mesa Boogie, Orange.   After 20 minutes playing the manager looked at me and smiled and said that he would not change one thing on the Iron Horse.  He was sold.
