“The idea behind the software is customisation. It all started when I couldn’t find a diagram of a left-handed fretboard tuned half-a-step-down and had to create my own. Then I tuned back to E and had to update my diagram. Then I wanted to share it with a right handed bass player and... well you get the idea. I realised that I needed to rebuild my diagram in an interactive format. Every feature followed from here.”
