Just got this today as I had become very interested in finding a fretless sixer with the close spacing I prefer. And Pete has become like my bass pusher. I'm definitely strung out on his creations. Fortunately, I can indulge this "addiction." I had some biz with Pete today and he put this in my hand. I put cash in his. The neck on this one absolutely blew me away! Have had little chance to do much with it yet...but I will! Look for a review soon. I can say initially that I've never touched a more effortless fretless neck and the sound is huge and warm. I'll know WAY more after I gig it on a double header next Saturday. For now, the details: Pro series, Nimbus body style. Wenge/Pau Amarello/Padauk 7 piece neck with Macassar Ebony board. Padauk top on Mahogany body.
