Pretty sure I have the sister to your bass, mine was made by Mike himself for the 2015 NAMM show; bet at one time mine was hanging right next to yours, out of curiosity is your serial number 2893 or 2895?
I totally understand, the EBSS is what got me turned unto short scales; I got mine the first year they came out in blue with a maple fretboard, feel special knowing there were only 100 made in this color.
