For used ones I've seen figures from $2300 to $3000. The very early ones are dearest, as expected. The new ones are priced comparably to Fodera and MTD and Canadian Dingwalls.
I brought it to an audition a few weeks ago, and everyone in the band had the same reaction after the first song we played together: "Holy $h!*, what IS that thing? It sounds friggin' AMAZING!!!"
Roger Glover plays one, or at least he did for many years. It's made in Paris. So they are not seen too often on this side of the pond. I was very lucky to come across the one I have - the serial # is in the low 40's, and I believe it was the only one made in this color.
