As mentioned above it is fretless with markers, low action so as to permit stopping the strings in a familiar (to me) way, plus of course steel strings, flat wound jazz strings to start with, 56 and 42 with the option to use flat wound bass strings of a heavier gauge if the tones are too bright, I really am making this up as I go along. It is of course a shot in the dark, but who knows it may actually work🤪
