We stuck with USB-A for a reason... there are a variety of USB-A to 9V, 12V, 15V and 18V converter cords available for use with pedals, but also the USB-A to USB-C and USB-A to lightning cables are readily available and very inexpensive so you get the best of both worlds.

Yes, I write all the basic outline and structure of the manuals, and then I have a couple of our outside test players who help with the editing process. One is a very experienced aerospace mechanical engineer who writes operations manuals for NATO compliant equipment (the big stuff) and the other has outstanding communication skills combined with really good intuition. Both are also excellent bass players (I'm a somewhat-mediocre keyboard player), so the goal is a technically complete manual written and edited from the perspective of bass players, to be accurate, clear, concise, useful and free from the vomitous marketing babble that makes manuals virtually unreadable.
Thank you for appreciating our efforts. ❤️ We figure that if you are going to pay for a premium product, you also deserve a premium manual.
