Lexicon MPX G2--using the EDP in the Effects Loop

["Clayton Gary Lehmann" <healthquestrecruiter@earthlink.net>]

I have acquired a G2 on  eBay which has not yet arrived.  I am hoping the
Looper in it will work well with the Echoplex with Loop IV.  I notice that
the G2 has an effects loop, and I read in the archives that Todd Reynolds
had some problems with that configuration.  Anybody here care to share 
their
experiences using these two units together?  Steve Lawson?  Also, do I
absolutely need the R1, or will the PMC work almost as well?
I specifically wonder if the software thru is toggleable--I'm gonna want to
use the internal clock as well as driving everything from the EDP.  Guess
I'll have lots of manual reading to do.  Unfortunately the manual is not
available online.
In other news, tomorrow morning I am the lucky recipient of rotator cuff
surgery on my right shoulder.  The good news is that I have some real good
health insurance.  I will, of course, be unable to play guitar for a while,
but ultimately I think this surgery will make me a better player.
Best to all and wish me luck,
Gary Lehmann
