Double Bass Full Circle + Shen SB-180

I do already have bridge adjusters, just curious if anyone knows off hand what size FC will fit?

I've done minor work on my bridge before and always change my own strings so I feel like it wouldn't be beyond me to install the Full Circle myself.

Think I'm correct in this assumption, or is installation better left to a professional luthier?

Thanks
 
Chances are that they are 1/4 x 20 threads (my Shen came with that thread pitch).

If you remove an adjuster, you can take it to a hardware store and find a matching nut--that will tell you what the diameter and pitch are. However, if you have a camera with a threaded hole to attach it to a tripod, see whether the adjuster fits. If so, it's 1/4 x 20.
 
The Full circle pu comes in two sizes as far as I know. The 1/4 " is the most common as far as I know and is most likely compatible with your Shen adjusters. What is the spec of your adjusters? Yes it is easy enough to install the Full Circle. Just take care that the sound post doesn't fall. Lay the bass on its back on some soft furnishings and apply some pressure to the top after loosening the strings ... heavy books or a willing assistant. It should only take a few minutes.
 
Thanks for the tips guys. I'm gonna give it a go myself, sounds like a quick and painless process. Really excited to finally try out the Full Circle!@

I thought Shen's shipped sans bridge and the luthier selling it cut one?

You could be right but most of the Shen's I've seen have a bridge with brown wooden adjustment wheels. My 80 and 180 both did, so I assumed it was stock.

When I bought my bass the luthier told me he tossed the stock bridge and carved his own, don't know what the original bridge looks like though.

The best is to ask your luthier about the thread size. Some order it in bulk from the factory so they come cheap.
 
I got my Shen 100 from FMI in Pasadena. They told me the Shens didn't arrive with bridges and they installed their own "deluxe" bridge at their shop.

Your best bet would be to do as Mr. Eisenman suggests and take one of your existing adjusters to your local hardware store and confirm that it's 1/4-20 thread diameter and pitch.
