I've lost the bulb on my Buster! Bass combo amp. It went and burned out on me in the middle of a gig. Scary for a few seconds, but ultimately, no biggie. My question is, besides the obvious source (mesa boogie), I was wondering of anyone else knows of places I could find these bulbs (GE #47). The web, or better yet places like Pep Boys... I know that the thermistor bulb in my Acme B4 was actually a tail-light lamp! I've also found bulbs for littlelight gooseneck lamps there. Just not the ol GE #47. Not yet, anyway! Thanx folks!
