Lego Guitar Hero Controller #2: B.C. Rich Warlock . The second working Lego Guitar Hero controller that I have made, designed after a B.C. Rich Warlock guitar. . This is the second Lego Guitar Hero controller I have made so far. I gutted the real controller, taking out the electronic boards and special working components, and placed them inside of a Lego chassis of my design. It is modeled off of a B.C. Rich Warlock guitar (a personal favorite of mine second only to the Explorer), which is a guitar I now own. Check my Brickshelf or Google "Warlock guitar" for a reference picture. I was not very careful when I built this guitar, so I screwed up the guitar's dimensions, elongating certain parts and shortening others.
The Lego controller works just as well as the real controller does. All of the components work correctly, from the Strum Bar to the Whammy Bar to the seven buttons on the guitar.
I made many radical and intelligent changes to this guitar. I only have one set of boards and components currently, so I wanted to be able to easily transfer from my Explorer to my Warlock (hence, I made things like the strap door, which holds a piece that holds the strap in place). The fret button board could be described as "Uni-body" instead of "frame-based," so repairs are easier. I made a custom Strum Bar with Technic gears, so it would be easier to grip than the bar on the real guitar. The inner structural supports use Duplo bricks instead of System bricks to minimize weight but keep the guitar together.
The only change I was forced to make was with the Start/Select buttons. First, the board for the buttons is not directly underneath the buttons, it's about 3 inches away. That meant I could not have the buttons where they were in the reference picture. I made the Start button a switch so that it could reach far enough. It's weird. I also added a white Katamari Damacy logo, and the PlayStation logo on the headstock.
All of these advances, and it still took less time to create than the Explorer.
