Club Sadowsky!!!

So what is the weight difference between chambered and unchambered?

Lets take a shot at a guesstimate: Say a typical bass body made of swamp ash comes in at about 3000 g (freedom units: 6.61 lbs). If chambering removes 20% of the bodies volume and assuming a consistent wood density over the whole volume, that'd mean a reduction of 600 g or 1.3 lbs.
If the same chambering is done to a body that comes in at a very light 2000 g, you'd shave off about 400 g or 0.9 lbs.
For chambering with 30% volume that would come in at about 600 to 900 g weight reduction (1.3 lbs to 2.0 lbs) and for chambering with 40% volume you'd be at 800 g to 1200 g weight reduction (1.8 lbs to 2.7 lbs).

Obviously, if the initial weight of the body is higher, the weight reduction from chambering is higher in absolute numbers, but stays the same at a relative scale.

All Fender style basses (and many others) have neck dive when seated.

I follow this thread since a short while, having the chance to trade an EBMM Reflex vs a 2010 Metroline :)
On the video - I've met Marcus at the Wicks HQ when I needed to replace a stuck trussrod on my '88 fretless thumb (5kg by the way, not to mention neck dive ;)).
Marcus is an amazing guy who can juggle few balls without losing control.
Hope to join here soon !!
 
Neck Dive
I wish I had a dollar for every time I have had to have this conversation.
All Fender style basses (and many others) have neck dive when seated. It does not matter if the bass weighs 7 pounds or 12 pounds.
When standing, neck dive is a function of the strap you use. If the back of your strap has a slick material (vinyl, shiny leather, etc), you will experience neck dive.
If your strap has a backing that provides more resistance (cotton, suede or anything with a rougher texture, your bass should remain in place, even if you let both hands off of the bass.
This bass weighs 7.44 pounds


This bass weighs 8.44 pounds.

Roger, thanks for chiming in. I think you tried to upload pictures but they didn't load.

While we have you, there is a bigger problem with the tuners in the German Metroline, which is not their weight. They are not smooth and they are inconsistent. They get stuck and feel like they are grinding. Several people on this forum are noticing the same. Can you please have a look at why this is happening?
 
My tried-and-true, NYC Will Lee 5 went under the knife this week and is now wearing a fresh set of soaps. Previously had the Sadowsky (Duncan) singles in it…which I actually liked a lot.

But, when I picked up a NYC 5-20 Ultra Vintage awhile back that had soaps, I was smitten (despite previously not really being enthused by the 60s position soaps based on videos I had watched). The soaps have a familiar j-bass tone because of location, but are just so fat and punchy.

I didn’t get along with wider neck of the 5-20 Ultra Vintage bass and ended up selling it. My Will Lee 5 is a keeper bass that’s got plenty of bumps and bruises, but feels like home. So, I had been going back and forth about having it routed for the soaps. Finally decided to just go for it and couldn’t be happier.

Hi Tim. I've bought it. We'll see when it arrives.
Well done, Marty. Just had a look and I see that the seller had changed it to metro express. I will be interested to hear what you think. The common "upgrade" on those seems to be to retrofit the standard sadowsky tone set up so that you get the vintage tone control, which imo is invaluable, but no doubt you have already done your homework. No doubt with your experience and skills you have already devised a way to do it yourself without purchasing a whole new loom. It is I think just a traditional fender capacitor to roll off the highs.

That is a metro express if we are looking at the same one. Does not have the usual Sadowsky logo so probably rsd on headstock. I think those are made in China? Still a nice bass but may need some fine tuning and certainly not in the same league as the marvellous Japanese metroline.

The auction was changed from MIJ in description to no details

Good one @Marty Forrer

Has the Ashdown arrived yet?
