SYLMAR, CA — Aspen Pittman, the legendary founder of Groove Tubes and Aspen Pittman Designs, passed away August 10, 2019, as the result of injuries suffered from an automobile crash in Southern California the day before. He was 70.

Aspen Pittman’s designs for guitar amplifiers, live and studio microphones, vacuum tubes and the M-S principle Center Point Stereo technology (US patent #6219426) for guitar speakers have been lauded by top engineers, producers and musicians for nearly 40 years. He also won the prestigious Microphone of the Year TEC Award for one of his innovative microphone designs. Pittman’s best-selling and now classic Tube Amp Book has sold more than 140,000 copies worldwide.

No plans for a memorial service have been announced. Pittman is survived by his adult daughter Autumn Pittman and will be missed by countless fans and many friends throughout the industry. He will not be forgotten.

Hi Everyone! Thanks for visiting my 1st web page. It will grow as I continue to have content to add. Just so all of you know, I will be leaving DSP Concepts on April 19th 2019. I am going it alone and working on new projects that interest me and some may actually generate cash again. Watch for more posts and thank you all who have been my friends for so many years. Terry
