I had never heard of the brand before but he has a website and seems to have a following http://www.krappyguitars.com/punkbass.htmlSomebody posted a pic of one of his Hofner-looking 2-strings here a couple of years back without any identification.
I met the owner/operator of Krappy a couple years back at a small festival in Raleigh where I was running sound.Very nice guy.BTW, I made that bass sound like it had 3-strings!
