I was searching for your definition including scale length because over the years, I have heard people refer to any tuning higher than a standard EADG as piccolo, so I wanted to make sure we were talking about the same thing. I don't have a tally of how many piccolo basses we've made, but my quick brain-index search says there are least 25 I can think of off the top of my head. These days it's one every year or two, we make more baritone guitars. Edwin has the shortest scale one, but we've made them up to 34" scale length.
