Shockman

Shockman is not a clone of any particular Rockman® product. It incorporates ideas from several Rockman models, as well as a great deal of original design. It's closest to an X100 without Echo (would that be an Ultralight?), with some nice features brought in from the Soloist (soft clipping, Doubler/Stereo mode, ability to turn off the Chorus), Ace series (9V power), and even a tiny bit of Sustainor. The active mixer with independent Aux In and Line Out, the headphone amp and the specific 9V power supply arrangement are all my original designs.

The rest of the design, while derivative, is heavily modified from the original schematics. I paid particular attention to noise optimizations, while also minimizing power consumption. I achieved this by carefully choosing the most appropriate modern op amps for each stage, and also by optimizing resistor values throughout the circuit to reduce their individual contribution to overall noise. Shockman has lower Equivalent Input Noise (EIN) than the typical self noise of an electric guitar, which becomes the limiting factor for the overall noise floor. It achieves this while drawing only 8mA of idle current from 9V -- almost an order of magnitude less than a Rockman X100 (~ 55mA from 12V).

Shockman contains around 160 components distributed on both sides of the 4-layer PCB. It uses seventeen op amps, an analog chorus chip (BBD) and a couple more supporting chips.
