I think the biggest difference besides the frets being closer together, which btw is probably not too hard to get used to (wasn't for me) and I have 34 and 35 basses, is the string tension.
Do not underestimate the fact that lower string tension can affect not only your sound, but more importantly, it will have an effect on the way you HAVE to play the instrument. As you adjust your playing technique to the shorter scale, you might be amazed at the new dynamics you are able to get out of your bass.
You really cannot play a 32 bass with the same force you would play a 35. This is assuming you like low action and have your basses setup with low action.
I love my 32 Persuader and am saving up for my 30 dream base! Alembic, of course.
I love stretching notes. I probably over-do it sometimes, but I am so looking forward to 30 scale!
