Jaco Tribute Bass Build

Yesterday saw the arrival of my pickups and grounding strap plate.

I was itching to solder, but I had to check the fit of not only the pickups, but the grounding strap and plate, as well.

With some light sanding via Dremel, the pickup cavities easily accomodate the pickups and shielding.

Dryfitting the pickups.

Taking a look at the pickups, I was amazed that they even aged the wires. Note the color difference between the pickup wire and new cloth wire.

I went to fit the grounding strap pickup plate and I ran into my first snag. The plate was just a hair too big, and its sharp edges would tear up my shielding job.

Removing the foam.

There is a nook routed out in the pickup cavity, so I plan to flip this plate over. This way the solder point is out of the way and closer to the entrance hole in the cavity.

The plate is too big.

So, I shave down the plate and round the corners. Presto! She fits.

Now that I have dry fitted the plate, I solder the bridge strap. The solder joint is good, but for added security, I add a piece of shielding tape.

Grounding strap installed!

Now that I secured my ground, and finished shielding the bridge cavity, it's time to install the pickup. The pickup goes in with little effort, and everything looks good. I go to open the fastner pakage, and while I'm impressed with the screws, the foam inserts have me scratching my head. They're all different sizes!

I take both sets of inserts from each pickup, and try to best match the same sizes up.

Along with the bridge pickup, I attach the bridge. However, I needed to relic the mounting screws, first.

Before/after.

Bridge and pickup istalled.

Both pickups installed with great success. Sorry, that was a ripoff from Borat. :D

Done!

Soldering tonight!

Awesome!

Did the plate come with the bridge pickup?
 
I removed the foam off the plate, because the pickup had a foam base. So yes, the pickup's foam is sandwiched between the plate and the pickup, saving it from any stress.

Ok cool.

I'm assuming you saw my post then?
It kind of looked like the plate was floating in the cavity, but then I looked closer at the pictures, and I guess they really were at the bottom, so I erased the post.

No worries. Yeah, the plate is laying flat on the bottom of the cavity. Buying the plate wasn't really necessary, but my OCD and Exaltbass would drive me crazy about it. ;)
 
I've been following this project with interest. Beats the heck out of buying the Fender models IF that's what one is going for. I'm sure there are some that would benefit from a run-down on costs when all is said and done (I've done builds, so I have an idea). Nice of you to share - something for everyone in this thread ;)

If I was trying to build a NOS Jaco artist series, then this project wouldn't be worth it. After all is said and done, this bass will cost over 1,800. However, the Fender Relic Jaco is like $4,100. Beyond the cost, I like the challenge of puting parts together. So much more fullfilling than just walking into a store and forking over cash.

Here are my costs:
Neck & Tuners: Ebay 463.00
Body & Control Plate: Atkinson 377.00
Bridge: Ebay 29.50
Pickups: BP Resource 175.53
Electronics: BP Resource 24.74
Strap Locks: Ebay 14.74
Labor: Kaufman 700.00
Grounding Plate: Ebay 12.97
Neck Screws: BP Resource 3.99
Knobs: Ebay 21.00
Total: 1,822.47

This includes shipping.
