I remember picking one up for the first time and finding the overall adjustment time incredibly short - my review of that very bass on the very day is still on YouTube. It was, for me at least, an easy transition, but I will agree that for some things adjustments are necessary. Jonathan Herrera has recently made a video of his first experience with a Dingwall bass, in the shape of the John Taylor Signature. He noted the same example as me, playing Minor 7th chords around the 15th fret and higher difficult (R b7 b3 or even R 5 b7 b3 arrangement) - that's easier on parallel frets I think. Most other techniques seemed to transfer easily - I was actually surprised that fast tapping was not that much more difficult, I thought I'd miss frets, but again, a small adjustment - and practice got me there. I liken it to getting a new car, a new, different car. Everything is in a different place, the brakes are sharper, the biting point on the clutch may feel different, the gate on the gears is tighter, buttons and switches are in a different place - it's frustrating and sometimes annoying, but we get over it and muscle memory kicks in quite quickly.
