Hi, I'm Mark Seel. I've been interested in electronics, engineering, music and software since I was a kid.  I've been fortunate to have a successful career in software and firmware, and in 2016 I started 3Degrees Audio to have another outlet for my interests in music and engineering. I'm excited to launch my first guitar pedal - BYGONES, and hope you enjoy it!  Here's a bit more about me:

• Over 25 years of Embedded Software and Firmware Architecture experience ranging from multi-threaded PC applications to low-power wireless communications to DSP-intensive applications to Bluetooth Low Energy System Design and Application Programming (BLTE, BLE).

• Consulted with numerous professional audio clients, including Presonus, Apogee, InMusic, Native Instruments, Keith McMillan Instruments (KMI), Chase Bliss Audio, XMOS and Bitstream Audio.

• Voracious inventor holding 5 patents. 

• Husband to Erin, who is partner with me at 3DA, and father to 3 adult 'kids' - Loren, Nick and Ryan. 

I enjoy helping other inventors and entrepreneurs with their projects. Feel free to reach out if we have similar interests!
