CS-3 Compression Sustainer Pedal

Q: Will this sound plesant on an acoustic guitar?

Not designed or used with acoustic instruments. Certainly not pleasant. Its a rock sound like Carlos Santana sustained notes in his solos.

Q: does this have true by pass?

NO currently-made Boss pedal has true bypass; all have buffered bypass.

Q: Will this sustain pinch harmonics so I can do a dive bomb?

It should - it definitely extends the sustain and harmonics on my guitars, using it through a Fender Twin Reverb or an old Peavy with a Marshall head. However, that is not really my style of playing (the dive bombs), so I can't give you a definitive answer. It will also depend on your amp setup and the guitar. What I can say is that this box does thin the sound a little, making it more sterile.
