It's good, there's just a few things wrong. For one thing, there's no option for text, even though jack often includes text on his thumbnails. Also, there's no saving feature. I spent ages making a thumbnail and after not using my phone for a few hours, I looked again and it was gone. So it's good, I just think it could be made better.
For those who don't know, a piccolo bass is a regular bass but tuned one octave higher, making it the exact same tuning as a guitar, except without the top two strings. I only heard about these recently, and my first thought was, "why not just use a guitar?". And I still stand by that thought. A guitar has the exact same tuning, and has two more strings, giving you more opportunities for higher notes. So what is the reason for a piccolo bass? Please let me know.
Last night I dreamt that I (somehow) got my hands on a vinyl of Songs From The Black Hole. For some reason it had night sky from the Pinkerton album cover as the background, and in the bottom left corner was what looked like the moon, with a small child on it. Absolutely zero idea how I remember it so well, or why it was like that and not like most of the fan recreations. Just thought it would be good to share it here.
