An Audio DSP Processor For Guitar

Here is a custom designed guitar effects processor which had reverb, digital delay, chorus effects and even a mode to display frequency on an oscilloscope.

This was a lot of fun to tie together my musical and electrical hobbies.
You may see my many musical fully produced songs at  www.mark-tunes.com

Details for those who are curious follow in summary:

The complex circuit board was my own Motorolla 56000 DSP designed board with very fast A/D and D/A units.   The Main control for the keyboard and display was using a 68331 based microprocessor circuit board I designed while working at Hewlett Packard and can be seen off to the right of the above picture.
