Doug sent it to me to play with for a couple weeks.
I think there are two mods. a basic mod, and the concert mod (more headroom).
Not sure what he does to the preamp section, but he disables all other I/O in order to buff it up.
He really likes it..and has been using this himself for a while.
so i'll mess w/it and see how it goes. Maybe it will kick ass...and my new Mme will be on the chopping block to buy one of these.
but I doubt it. I have my heart set on the Mme>flashtracker.
