I got an ICON from my wife for an anniversary present about 4 years ago now. It was one of the first few imported to the U.S.
Truth be told, I did not care for it much at first. As noted above, the earliest imports had serious construction issues (sharp fret ends, buzzing pickup surrounds and pickguard, poorly crafted floating bridge.) But, because it was a gift, I knew I could never trade her. So, I rolled up my sleeves and went to work. Filed the fret ends and the back of the neck with a little steel wool. That took care of that. Similarly, I shaved the pickguard to eliminate buzzing. Finally, I shaved the top of the bridge on the treble side, just behind the saddles to elimate the strings hitting the back of the bridge and throwing off intonation. Finally, I strung her up with rotosound monel flats (short scale) and gave her a good set up.
All I can say is WOW!!!!. This is a different instument. A little TLC made this ICON every bit the sonic equal of my old Hofner 500/1. It is really that good.
And its not just my sentimentality taking over. I have loaned this one out for recordings and gigs to other pros and had to beg to get it back from them. Everyone loves it.
Just for comparison, I did play a new Contemporary series bass when they came out. It did not have the same McCartney vibe as the ICON. It looked the part -- for sure. Maybe even more so than the ICON. But the CT series has that center block neither the ICON nor the original 500/1 has. As a result, it just didn't have that true hollowbody "bloom" for lack of a better word.
In the end, knowing what I know now, I would buy the ICON all over again. It likely won't be perfect when you get it (maybe not even close). But everything you need is there. With a good set up and a little TLC, I'll bet you will be more than 100% satisfied with the result.
Just do it!
