***UPDATE***

The bass was found. And delivered at Tom Petersson's address today! It appears to be undamaged.

---------------

That black twelve-string bass that I built for Tom Petersson is only half the story.
I built another twelve-string bass for Tom. And they were finished simultaneously.
Both basses were sent off to Tom's address on June 29th.
The black one was delivered four days later.
But the other one (with quilted maple top) still has not been delivered. UPS has lost the package...
I filed a claim for investigation on July 16. But still no sign of the bass to this day!

I am gutted.

I'm still keeping my fingers crossed that it will show up in the UPS warehouse after all.
But if you should ever see this bass for sale, please do contact me.


Here are the pics that I took before I sent it off to the USA

As with the black twelve string bass it started with the body blank and neck blank.
I had my wood supplier make them to my exact specs.

A nine-ply khaya (mahogany) neck with walnut strips in between.
And a two piece body blank of the same Khaya.

Routed the channel for the carbon strip in the middle

As well as the tapering slots for the two truss rods.

brooks-exb-12-tp-routing-black-trussrod-channels_orig.jpg
brooks-exb-12-tp-black-trussrod-channels_orig.jpg



Then prepared the fretboard.

Drilled the holes for the inlays.

brooks-exb-12-tp-drilling-inlay-holes_orig.jpg



Glued in the position dots. And aluminum ring for the twelfth position.
Sanded it flush with the 16" radius block.


brooks-exb-12-tp-inlays-ready_orig.jpg



Prepared the frets by cutting off the tang on the edges

brooks-exb-12-tp-freybaord-ready-for-fretting_orig.jpg



Hammered them in and used the arbor press to have them seated perfectly

brooks-exb-12-tp-hammering-in-the-frets_orig.jpg
 
After I glued on the fretted fretboard I shape the neck profile (sorry npo pics)

And I drilled the tuner holes

brooks-exb-12-tp-drilling-tuner-holes2_orig.jpg



Shaped the headstock outline

brooks-exb-12-tp-tuner-holes2_orig.jpg


Then cleaned up the front and back of the headstock.

brooks-exb-12-tp-tuner-holes-ready2_orig.jpg
brooks-exb-12-tp-tuner-holes-back2_orig.jpg




Drilled the little holes in the side of the fretboard, for the side position markers.

brooks-exb-12-tp-drilling-side-markers_orig.jpg



Glued them in.

brooks-exb-12-tp-making-12th-side-marker_orig.jpg



And sanded them flush

brooks-exb-12-tp-12th-side-marker_orig.jpg



Filled the gaps underneath the frets with a mix of ebony saw dust and Titebond Original

brooks-exb-12-tp-filling-fret-gaps_orig.jpg
 
Drilled holes for weight relief in the body blank and routed the cavities and channels for the wiring

brooks-exb-12-tp-weight-relief_orig.jpg




Bought a beautiful bookmatched Quilted Maple top set at my wood supplier (Masave in Zwolle The Netherlands)

brooks-exb-12-tp-very-wide-quilt-set_orig.jpg



Glued the top op. You can never have enough clamps ;-)


brooks-exb-12-tp-clamping-quilt-set_orig.jpg



Let it sit for a couple of hours

And then routed the body outline.


brooks-exb-12-tp-body-outlien-routed2_orig.jpg
 
Routed the channel for the first step of the checkerboard binding.

brooks-exb-12-tp-body-outline-routed2_orig.jpeg



Glued in the strips of checkerboard binding. On the sharp corners it's actually done block by block.

brooks-exb-12-tp-lots-of-tape_orig.jpeg
brooks-exb-12-tp-first-step-checkerboard-binding-done_orig.jpeg




The routed away the black fiber strip in the outside. And glued in the real outer binding.
I use a hairdryer to soften the binding where it has to make a sharp corner.

brooks-exb-12-tp-heating-binding-corner_orig.jpeg





When everything was in place I used the strips of inner bicycle tubes to keep it all clamped, while it dried and hardened.

brooks-exb-12-tp-clamping-outer-binding2_orig.jpeg



The two bodies were ready at the same time

brooks-exb-12-tp-two-bodies_orig.jpeg
 
While the lacquer cured, I started to prepare the tuners for installment.
Like I mentioned in the thread of the other bass that I built for Tom Petersson I modified the Schaller tuners a little bit.

Two reasons: Save weight. And to make them shorter in order to keep the headstock as small as possible (without sacrificing strength of the wood).

After I had wet sanded and polished the bass, I installed al the hardware and electronics.

brooks-exb-12-tp-pickups-mounted-quilt_orig.jpeg
brooks-exb-12-tp-quilt-sans-bridge_orig.jpeg



Initially the bass was designed with a pearloid pickguard (which matches the pearloid buttons of the octave tuners)

But when I saw the beautiful quilted maple top I got second thoughts. And suggested we'd leave the pickguard off.
Tom agreed to leave it off.

But I did make some pics with the pickguard that I already had cut out.
I used cut off head of phillips crews to make it look as if it was really mounted. So no holes were drilled in that quilted maple top.

brooks-exb-12-tp-lower-horn-pg-1500_orig.jpg

brooks-exb-12-tp-diagonal-body-pg-1500_orig.jpg



I put the pickguard inside the case. So if Tom should change his mind he can always decide to mount it after all.

I saw, and heard, the black one on Tuesday night. it was thunerous of course. Last time I saw the band (30 yrs ago), Tom was playing an 8 string bass if I remember correctly. Watching him this week I was counting the tuning machines and was amazed that this was a 12er.
Rick, my age, looked really frail and weak but still played all the licks and solos.

That bass you saw 30 years ago must have been a 12-string as well. Tom basically invented the 12-string bass in the late 70's. And has been playing them ever since.

Yes, I saw some footage of the Toronto show. Rick did look like he could use a rolling walker on stage yes.

I'm still learning. Other people were talking about an 8 string-er and I didn't know enough about it to correct them. Back then Tom played through a Rickenbacker (at least the cab) but it was not there this week.
