I'm retired from gigging (for now) but this was made when I was still an active musician. It's dedicated to my fellow gigging musicians, specifically those spankers of the plank, who need to keep the top of their enormous amp clean. But it also has the usual mounting holes in the back to accept 3mm x 5mm neodymium magnets, turning it into a magnetic plaque.
The surround of course can be printed in whichever colour you think will look best. Enjoy!
