I have owned two of them...Top notch instruments made with a lot of attention to detail. The electronics are great and the tonal options are many. The price is a bit high for a used one without a top. They generally go for around the $2K range. There is no way he paid $3700 for it. I paid $2400 new for one almost identical to this one about a year ago. Check this guy out if you want one. You can probably get it new for less than the used one listed on CL
