Wiard

Grant Richter builds the Wiard series of modules. His older, recently reintroduced, 300 Series modules are highly sought after (in 6U format.) Now discontinued 1200 Series modules were built by Grant himself and are based on the "Frac-rack" (3U) system. They require plus or minus 15v power and are calibrated 1v/octave. Connections are 1/8" mini-jacks. Currently available modules include a joystick, the Joystick Axis Generator, Noise Ring, and the Borg and Boogie Filters. (excerpted from Doug Wellington's excellent Analog Notes site).

Currently, older Wiard designs are being reissued and new ones are being introduced in Eurorack format by Malekko.

Several Wiard designs have been licensed for production by other manufacturers:

Makenoise Wogglebug

Additionally, the "Wogglebug #3" design has been left available to the public by Wiard, and heavily embraced by the Synth DIY community
