Just thought I'd share this with all you folks.Wanna see a true k-mart blue light special microphone?I made this from a real k-mart blue light.It has the head of a d-104,the amp board is from a turner hand mic and is switched by a 12v relay controlled by an old computer game joystick.I put 12v lights inside that light up when you key.Really sounds loud and clear.Even put a rotary pot volume control on it.Too much time on my hands!
