Well, this has been an odd story. I received my pickguard from Mark a few days after my previous post. It looked great, but was too large for my bass, a 2020 Rickenbacker 4003W - so large that the edge of the pickguard would have been hanging off the edge of the bass's body! I had pre-approved the template Mark used to cut the pickguard (after a cursory look - my bad), so I didn't expect any action on his part, but I did contact him to let him know that the pickguard "as is" was not usable. To my surprise, he offered to cut me a new one ... IF I provided him with a full-size tracing of my current pickguard to use as his template. Reasonable request, I thought. I made a tracing and sent it to Prague. But as of this writing four weeks later, the tracing apparently hasn't been received. (It took only two weeks for my pickguard to get from Prague to the U.S. east coast, and the U.S. Post Office estimated delivery of my package to Mark within three weeks.) To make things even more interesting, my emails to Mark are now bouncing, with international email servers treating his address as a spam source.
However, there is a happy ending. While the pickguard Mark cut for me was too big for my Ric, the routs and screw-holes in it were properly placed. Given that, I took out my rotary cutting tool and diamond files to see if I could trim the pickguard down to proper size. The photo shows the result.
