Here's a bass from Italy called the Laurus Quasar
SL-20 (good name). As you can see, Gumby is a headstock design.
For your convenience, I've included a picture for your comparison
pleasure. (And hey, stop bugging me about this bass - I really like it, just like how I like Gumby, okay?! Had a chance to play a 6 string one and it was super!!! (thanks for the picture andy!)
