Keyboard manufacturers have been prominantly placing their corporate logos on the rear of their instruments for a long time. That makes sense — the equipment is going to be on stage and it's good to get your name out there facing the audience and photographers.

And some intrepid musicians have hacked the keyboard manufacturers' logos to personalize them. Let's take a look at some examples.

Here's one of my favorite musicians, Sigmund Snopek of Milwaukee. You can see how he's tweaked the Roland logo on his keyboard to express his ethnic heritage. Excellent.

And here's Ron Mael of the band Sparks on Saturday Night Live. He's swapped two letters on his Roland keyboard to spell out his first name. Clever.

And finally (here it comes...) here's Amanda Palmer of the Dresden Dolls with her Kurzweil...

Yeah!
