I have an MPX-G2 and looked for an additional box for extra reverb. I 
loooove the G2, especially the great reverb and looong delay (20 secs 
mono, 10 secs stereo).

Tried the MPX500 and the MPX1.  

The MPX500 sounds different, the algo's are not identical to the G2. 
It's nice but different and imo of a lower quality. The 500 produces 
LOTS of noise, however, revealed when the lowpass filter is opened. 
The noise was too much for me.

The MPX1 sounds very much like the G2, which isn't a surprise, as the 
G2 was based on the MPX1, but updated with 24-bit hardware (ADDA), 
and with added guitar effects of course. The interface of the MPX1 is 
similar to the G2. The reverb algos are identical and produce the 
same character. The noise level is similar to that of the G2 (good, 
imo). 

However, the aged ADDAs of the MPX1 could clearly be heard when 
listening to the reverb tail. Using an exactly same algo on both 
machines (a 10 sec hall), the MPX1 introduced conversion noise at 
about 60% of the tail, while the G2 stayed clean all the way. 
Especially for ambient productions, where I have stuff *swimming* in 
my G2 reverb, the MPX1 would introduce way too much artifacts. So 
even the mighty MPX1 could not meet my requirements, which was a big 
surprise for me.

I finally got an TC M-one, which I'm starting to like more and more. 
It has a *very* different reverb character (cleaner, more open and 
neutral), but it sounds good. And when I find a second-hand MPX-G2 
I'll buy it right away.
