This keyboard built by Waterhed was quickly swiped after the BIN was set at $89. Kind of a neat design and I like the see through red plexi glass panel. The paint job looks good in this image, however I spray painted some wood yellow once and it didn’t turn out the greatest. These square wave keyboards are pretty nice to mod considering there is a manual out for them. Despite their cheapness they sound rich and very Atari like especially when pitched way down thanks to the square wave sound generation. Apparently this one also has an LFO circuit with optical pitch controls built-in. Earlier post on October 71’s mod of a similar HH keyboard can be seen here.
