Hey Guys:
Yes, as Dave said the hum cancelling pickup is located under the mustache tailpiece. Which is another feature of this bass I love. The battries go in a compartment between the pickups with a brass cover that screws down on it. Besides the beautiful woods used, it has a very cool scalloped brass nut I believe was manufactured by Rick Turner when he was still with Alembic. I emailed him a couple times and sent him a picture and he said he remembers making my bass. That was really cool. It is in such incredible shape because for a part of it's life it lived in my best friends closet! When I was young and foolish I actually sold it to him for awhile but he hardly ever used it. Never gigged with it. Fortunately for me he sold it back to me years later, practically unused. And for my part I NEVER take this on long trips that involve flying. It's just too precious. So thank you for your kind comments about how well cared for it is - I really work hard to keep it as pristine as I can. It has an oil finish so I give it a good Watco treatment at least once a year. And the brass work is cleaned a couple times a year. The last time I cleaned the brass I even took apart the brass bridge!! It took me an entire day to clean it and put it back together again and another few hours to get the intonation perfect. But it was worth it. It looked incredible. Like I had reached back through some mystical time machine and plucked it from the Alembic workshop in 1974. I had Alembic go through the electronics a few years ago and replace a couple of resistors, pots and such but outside that it's original. I still have my original reciept from where I purchased it in south Tacoma. Price: (this is gonna hurt Guys,) a whopping $1275.00!!! And back then THAT was considered a HUGE ammount of money to spend on a bass guitar. But the second I saw it there I knew I had to own it. It was like nothing I had ever seen in my life. Obviously painstakingly handmade with TLC! And the groundbreaking active electronics have allowed me to dial-in the most original and sonorous tones. Here are a couple more detail pictures showing the nut and the back of the body.
