A note from Shane:  In researching various obscure musical instruments, I have discovered the treasure trove of information from Mugwumps, a now defunct magazine originally published by Michael Holmes of Silver Spring, MD.  The bi-monthly journal celebrated old time music, unusual folk instruments and served as a classifieds for the emerging bluegrass community of the 1970's.  

Mugwumps was one of the first publications to reprint old patents and present plans for instruments such as this improved gut bucket bass.  To my knowledge, all Mugwumps issues are completely out of print and not available in reprint.  I present these plans to you as an easy-to-download PDF.  Print them out and build away.
