This Radius 540R is the predecessor to the Joe Satriani models.  It's very similar.  The tremelo is the edge and has a spring mechanism in the back that adjusts the tension of the bar.  It's a floating tremelo but you can bend a string without the others going out of tune.  The bridge pickup is a blue FRED.  I used a sharpy permanent marker to make it black.  You can see how permanent it is.  The arrow points to a chip through to the wood by the strap button.  The button is unaffected and works fine.

A closeup of the chip.  There are other dings, blemishes etc. but nothing more like this.

The prestige case is in poor condition.  Missing a clasp and another broken.  The plastic is also warped, but it protects the guitar.

Arrows pointing to case flaws.
