so far i've found that some things go better with the Epsi than others. the 11R is the perfect matchup for the Epsi. what it does for the 11R is fantastic in that it takes it to another level. my Bugera amp didn't benefit from the Epsi as much as the 11R did. sure it was cool to play through the Epsi, but it didn't retain the power amp interaction like the 11R did.

more experimenting to come...
