Hi man,
I've set up a few hollow bodies (semi-acoustic) for
slide for some students in the past.
From my experience, some sound great, but some have a very muddy thudding sound, which I personally didn't like.
These were mostly lower to mid priced brands, (Ibanez, Aria Pro, etc).
However, all guitars sound different, even same brand, same model.
I expect more expensive brands like Gibson would have a much better tone, and more sustain.
I recently set-up an early 60's Harmony hollow body and it sounds great; but still, it thuds a little.
As mentioned by Kirk and Barry, feedback can be a hassle also, especially with lots of Over-Drive.
