If you look at the chorus of the JX-8P and JX-10, you will find a 
limiter in the input for the BBD-lines. (see 
http://www.florian-anwander.de/roland_string_choruses/JX-8P_schem.jpg). 
Appearently the roland engineers found that the JX-3P can overdrive its 
chorus; assumingly they wanted to avoid that without making the 
sound/noise ratio worse. This limiter is not(!) in the signal path of 
the dry signal that will be mixed with the BBD signal, so it might be 
that percussive sounds with chorus are more "incisive" at the JX-8P than 
on the 3P. I can't test this, as I do not own a 8P. But I simulated it 
using a Kord SDD-1200, which worked like the two BBD lines. The delay 
was fed by the compressed original signal, but the output mix (which is 
the chorus then) was done with the uncompressed signal. Playing this 
with piano like sounds or similar was quite stunning. Crisp attack, but 
smooth and wide hold phase.
