Just thought I would show off my Electrovibe build. Big thanks to Big Monk's modification thread. I did the volume and speed resistor changes and it worked out well.
The bigger chicken head knobs work fine and the pointers clear each other. One tip for enlarging the hole in the face plate I used was a lexan reamer I have from RC Car hobbies. It also works well on the aluminum enclosures if your hole is a little tight.
