DH Pitch Shifter
Thanks to Dean Hazelwanter for this project. This is a great effect with lots of possible sounds available. The board will fit in a Hammond 1590C size box with the board under the pots and switches. The HT8950 IC (18 pin version) is available from Small Bear Electronics LLC.

Here’s a photo of our prototype circuit board. Note that I used a jumper in R3 to level out the dry/wet signal.
