Cool... That's a PF-5 preamp w the trim pots mounted on the face of the instrument... Nothing unusual for the year... Cool guitar~ nice to see it for the sake of the archives!...

Very cool. I want to know where to get one of those pickup selector knobs!

Edwin ,  
            Those knobs look like one of the swell selections from Raytheon in the 1970's. I have two on Kit preamp .

Nice!

I am a little skeptical when the seller claims to have had Alembic go throught the guitar 5 years ago, but doesn't know what the controls are for. (Pre-amp gains are attenuators and Q switches are phase selectors? ).  Cool old Alembic medium scale, not a prototype,  and priced way too high, in my opinion.  
 
Bill, tgo

I know I posted about this in a previous thread on this guitar.
 
That guitar is the very guitar in the L.D. Heater brochure from 1973.  Although it was not born with the pickguard, you can see in the brochure that the pickup selector knob is the same one in the eBay pictures.  
 
I have the bass from the same brochure, Serial number 73 49.

Hi Michael,
 
There is 73' 47 on the L.D. Heater brochur.
I know you also owned 74' 49 birdseye maple top.
 

Sorry EIji,  I meant to say that the bass in the brochure is 73 47.  It has a walnut top and back. Number 49 is a Birdseye maple bass and is not the bass in the brochure.  
 
I've had too many basses.

Speaking of your many basses, Michael, any word on the hurricane restoration?
