The Fatboy

The Fatboy is near production! We just finished our first production level version and after a few more tests and listening sessions we will be ready to bring down the hammer and have it available as an upgrade for all VPI tables at any length.

Features:
- JMW Uni-pivot design with included Stabilizer (AKA Dual Pivot)
- Available in any length (9, 10, 12 though we prefer 12")
- Thicker 3D printed arm tube with a mild taper and gloss finish
- Adjustable Azimuth via set-screws on the side of the tube
- Adjustable threaded side outrigger weights
- Integrated into a machined black anodized hub
- Fine adjustment counter-weight with locking screws

(Cat not included!)

Projected price?

Effective mass for the 12”?

Wiring?

I have seen pictures of the Fatboy with a metal azimuth ring, this one appears to be 3D printed. Could you please confirm the construction?

The bell-housing / azimuth ring looks to me like painted / anodized metal...not 3D material.

Mat, what are the chances of VPI manufacturing 3D printed arms that will be the same effective length as the original 10" arm (as opposed to the newer 10.5" arm)?

Is this a picture of the prototype? Finish looks pretty rough for a final product. The 3d part of the arm looks very much like the original 12" tapered 3D arm.

Can we assume a reference version with a more exotic looking finish and Nordost wire will follow?

Is this arm intended to surpass the Sonic's of the current 3DR or simply to add an arm that is better suited to low compliance cartridges?

Mat stated in his post that the back section of the arm is a machined anodized hub (aluminum.)

I much prefer the look of this version.

Will the main counterweight be on a threaded rod like the above photo? Would love to see that for easier and more precise VTF adjustment.

Do you find this one aesthetically pleasing?

This one Looks a lot cleaner to me than the one in Mat's picture....It looks good, but if this thing is going to retail where I think it will, it best be spectacularly well finished..That said, how long before the the "you name it" finish version with Nordost wiring shows up? May have to trade my 12" Classic metal arm that I use for my ZERO for a "Fat Boy"....

Can we get some figures for the effective mass?, availability timeframe & pricing? I would sure love to try one out with my Mono Cartridge! Hey Mat - I am a volunteering Guinea Pig :lol: :lol:


I also agree with Johnny that the azimuth ring in natural metal finish looks richer/better/more luxurious/ more expensive/etc.. than the black anodized base (particularly so if the arm support is going to be black)......FWIW

Hey all,

Just to give more information on this, this arm has been slow to bring to production because of us making sure we covered everything from an engineering standpoint and from feedback via both you the customers as well as our distribution partners. The change from the open thread to the fine adjustment knob was for exactly that reason, finer adjustment. The larger thread was both visually not as appealing, and more difficult for finely turning the counter weight. The change has made it easier than ever to adjust tracking force.

The change in the hub was because of the weight. The effective mass was too high in the original prototype and had issues with compatibility with some cartridges. This arm is meant to have the widest level of compatibility with cartridges than any arm we have ever made. The hub in this way makes it one piece (less chance for vibration) all black anodizes and brought to an appropriate mass. Now that we have tested and run the first full production arm we are at the "pencils down" stage and will make all of the technical and pricing information available soon :) I also want to working something out to help those who already own a VPI arm and want to trade up to this arm.

It will be available in 9, 10, and 12 to cover all opinions of which length is "the best length". We still prefer and recommend 12, but we will never force and tell someone their listening preference ins wrong.
