anyone has some interesting guitar power amp based on this IC? I have one (thanks RLBJR65) here and it would be nice to make something of it.
Thanks

It looks a lot like an LM386, plenty of LM386 projects around.

Initially I thought it was the same chip except the larger pakage allow it to output more power, but looking a little more closely it's not quite the same.  For example it LM388 uses a bootstrap cap instead of the internal current source to drive the output stage - that means the LM388 circuit will need an extra cap across pins 13 and 9.
