I found your posts. Good gosh, I can't even search my own thread!

I must have missed them at the time.
I like this idea much better than the adapters. They look terrific, like they belong on the bass, vs. the adapters look like they are just "hung on". I'll watch for them on eBay, and may contact Matt directly through eBay as well.
Hopefully, he can sell enough of these to justify continuing to make them.
The JCustom ones on HeadlessUSA look good too, but as I mentioned, HeadlessUSA is showing out of stock and I don't see any other online presence for JCustom. It must be a HeadlessUSA exclusive.
