PCB In Gibsons:

Smitty,

One more thing...and this dawned on me last night while measuring pickup impedance...shielding is also a challenge with a PCB because you can bridge all the solder joints on the back....PCB.JPG

Also, the control cavity on a PCB equipped SG is different too...

The cavity geometry on the SG with the PCB looks really familiar.

It is almost the same size and shape as on my 1974 Gibson SG.

I guess to fit the PCB Gibson had to do a throw-back to the '70s! The cover even uses 5 screws, like my '74.

The more things change...well...you know the rest.

I've reached out to Molex for you. We'll see what they come back with for a part number for the crimp tool.

I don't know if this is still worthwhile to mention, but the part number for the crimp tool is 63819-000.


http://www.molex.com/molex/products/datasheet.jsp?part=active/0638190000_APPLICATION_TOOLIN.xml

It's available from Mouser for just over $345.00

Ummm....yeah...I'd be using needlenose pliers! $345.00 goes a long way towards other gear.

Not cheap are they???? I agree with you. It would be easy to modify a pair of needlenose pliers to serve as a crimping tool.

Fortunately, I scored a pair of the 2017 Gibson 490's from a 2017 Les Paul Tribute that are already Quick Connects.

I really appreciate you digging this information up...

Also figured out how to shield the cavity by using black tape over the solder points on the back of the PCB.
 
I read a shootout on vintage wiring vs PCB and the consensus was, IF tone pot and cap values are IDENTICAL, there was no discernable difference in tone...
 
After much work, thought, advice and deliberation, I am ditching the PCB....

Looks like I'm going with a custom harness...Tone Man struck me in the wallet...

Bournes 500k pots,
(2) audio taper potentiometers (volume)
(2) linear taper potentiometers (tone)
1 – PIO K40Y-9 Russian .033uf / 400v Capacitor (Bridge Tone Cap)
1 - PIO K40Y-9 Russian .015uf / 400v Capacitor (Neck Tone Cap)
1 - Switchcraft 3-Way Right Angle Toggle Switch with black tip
1 - Switchcraft 1/4 Output Jack
1 – 50’s style cloth push back 22awg wiring through out

Funny....I have spent more on this 2016 Gibson SG in 3 months than on my 1987 Stratocaster in 30 years....and I must have changed pickups in that think a dozen times!!!!
