okay i bought the istrobosoft cable, and i'm less than impressed. Half the time it doesn't correctly recognise ANY of the open strings (regularly shows the B as F# and the E as B!), and struggles anywhere on the B and E. On top of that, when i 'tune' it up to istrobosoft it appears out of tune on the other tuner i have on there, so i now have no idea which is right.
This thing gets good reviews, iv tried it loud and quite, thumb stroked and plucked, direct from bass and from mixer, all as warbley and inaccurate as the other.
