Genz Benz nubby textured tolex

It was a more custom OEM type product that had to be bought in large quantities.

You might be able to find something passably close from stock product vendors but it won't be identical, and probably not quite that heavy. Note that the heavy materials take a lot of extra effort and work to apply properly and look awful when not applied properly, which may be part of why they are not commonly used for high volume production.

 

Yup, close enough is probably going to have to work here. The original material works best when it's reasonably warm, an advantage of manufactuiring in Phoenix. Now I suppose warm is relative, but as they say, it's a "dry heat". From experience, never pick up a tool that has been left out in the sun without gloves... you might just as well pick up a soldering iron by the business end.
