Just got this and have been very happy BUT I've been waiting for a long time to pick up a Puma 900. One just popped up on the classifieds and I jumped on it so now this has to go. Was told it was a demo model for NAMM. Has no serial number but does appear to have original box, but no serial number on that either. In excellent condition with light scratches on bottom and barely visible scratches on top. Sounds great and works perfectly. $575.00 shipped USA only. Paypal ok.
