Wozzit Weigh? In pursuit of a definitive thread (Fender jazz edition)

[LawrenceH]

I've been investigating lightening the load of my main player. I measured weights of various components and since I've put in the work thought I may as well share, it might be a useful resource for anyone else thinking about weight reduction on a jazz bass or looking to put together a bitsa. Haven't fully dismantled it so don't have separate weights for control plate components or pickups, but I'll try and revisit at a later date next time I restring. Cheap-o Ikea digital scales so expect a small %age inaccuracy, though it did test ok on some kitchen weights . Also taken a few measurements from an Aerodyne jazz for comparison, less than 300g lighter but strangely feels like a bigger difference.

 

If anyone else has some components to add please chip in! Different tuner designs, original BBOT/high mass bridges, pickups, covers etc. Also neck and bodies as it's useful to see where the weight comes from and what the variance is. Will try and add some pics at some point too

 

Japanese Fender 75RI:

Neck (maple board) 773g

String tree 7g

Tuners (Fender 70s style) 445g (111g each)

3-bolt neck plate plus bolts 66g

Pickguard 94g

Pickguard screws 6g

Control plate 148g

Fender Deluxe Bass Bridge 106g

Body (ash) plus DiMarzio Model J pickups 2682g

Strings 75g

Total: 4402g (9.70lb)

 

Fender Aerodyne Jazz:

Neck (defretted, epoxied rosewood board) 703g

Tuners 370g (92.5g each)

String tree 7g

4 bolt neck plate plus bolts 64g

Body (basswood) fully loaded (pots, bridge, P/J pickups) 2899g

Strings 75g

Total: 4118g (9.08lb)

 

CTS 250k pots solid shaft from my spares drawer 14g

 

Hope this is useful info to someone!

It's this kind of dedication that makes Basschat what it is

I can definitely see an obsession building. Scratch plate? Pah! That's 100g of dead weight with the screws!

If I bought a lathe I could mill up a titanium string tree and save 3 grams.

I’d say the reason why the Aerodyne feels a fair bit lighter than the 75RI is the difference in weight of the neck & tuners, might not seem much difference but it all pulls on the shoulder.

Yup absolutely right Lozz, though the bass doesn't exhibit obvious neck dive when worn. But those tuners are unnecessarily chunky. Annoyingly there doesn't seem to be an ultralight version of the 70s style tuners so changing them involves drilling new holes.

 

I do have some Gotoh Resolite GRL510C12 - hard to get in the UK - and they're only 180g for the complete set. So I can lose an impressive 265g off the headstock. Worth noting though that the Gotoh clover isn't quite the same as the Fender one, and the shaft is a little shorter

Beware: you are walking on dangerous path. 

 

My latest road bike was 6.6 kg, and 6.8 kg with a power meter hub. 

 

I loved pages like this:

...although I never had the money to buy a set. I still have this:

...and some other nice parts in some boxes in the basement. Carbon, Ti, Mg, fiber reinforced composites... there are many materials that could be used in lightweight basses.
