This bass saxophone immediately caught my eye yesterday when I first saw it. I wished I lived closer so that I could give it a try, because I must admit, I’ve been curious about the SX-90 bass for quite some time.

Keilwerth bass saxophones are just not seen very often—with a notable exception being in and around the Philly area, where you can find them more in string bands, than most likely anywhere else in North America.
This bass belongs to a former member of the Denville string band. Here’s how the sax is being described by the seller:
This is a (approx.) 2000 Keilwerth bass saxophone. I’ve used it for 5 years in a NJ band specializing in 1910′s to 1920′s traditional Philadelphia String Band music (banjo, sax and accordion). I’m moving to NC in a few months and can’t find a band down there where it’ll fit in, so I’m back to playing tenor and bari. I bought it in 2005 from an airline pilot that was newly retired and planning to travel and had no use for it. This sax is in very good to excellent condition. You can see in the photos that I’ve applied peel-and-stick vinyl shelf liner to the body to protect the finish from belt buckles and chair rash, and it’s easily removed. An arrow in one photo points to a dent – I confess – I caused it… I dropped it on the edge of the case while putting it away. It’s not a big deal, basses collect more dents than dust and this one doesn’t affect anything but my ego.
There is a bit of lacquer spotting as you might expect. I’d put the finish at 98%. The neck is in perfect condition. The mouthpiece is a 50′s Selmer and is included as is the ligature. It’s had a baffle added and helps this bass play as easily as any tenor. The case is the original and except for a few scuffs is in excellent condition with wheels added at one end. The wheels are a good thing to have on a beast like this. the stand is also included and is perfect for playing while seated.
I encourage you to come play this in person before bidding. It’ll knock your socks off! I’m located in Stirling, NJ 07980. US 48 sale only.
Sells new for $17,000.00 at Woodwind and Brasswind.

Since I’m not familiar with Keilwerth bass saxes in an up close & personal way, I don’t know what is located near the lyre holder and screw. In this photo I’m not sure what this black material is. I’m thinking maybe electrician’s tape? Is it, and whatever that translucent material with it is, part of the protection the owner added to protect the finish?

This must be where the dent is that the owner mentions. I’m not sure I can see the dent, so it must not be too big.

The bow looks to be in very nice shape, and doesn’t seem to have any visible dents. Note the added protection added to the bow guard. This owner was very fastidious about protecting his horn from damage.

The sink trap neck really does seem to be in pristine condition. Did this sax ever get played more than a few times a year? I’m thinking not.
