Historical Perspective of JamExpand™

 

The inventor is originally from Ohio which is the same state singer and song writer Phil Keaggy grew up in. Phil Keaggy became one of the masters of using the JamMan® in live performances. The inventor, after seeing Phil Keaggy in a live performance, was inspired and acquired a JamMan®. It should be mentioned the inventor is also a guitarist and an electronics design engineer with over 30 years of analog and digital signal processing design experience. Motivated simply by the challenge and desire for more sample time in the JamMan®, the inventor began to explore how to increase the memory despite the minor fact it was never designed to operate with more than 32 seconds of memory. After several years (having a full time day job) he developed the proprietary technology and released this product. The initial product is JamExpand™ with 17 minutes and 53 seconds of memory. The technology is currently Patent Pending.
