Have you tried coming out of the 11r 1/4" amp out puts to the Epsi C the to the amp or guitar to Epsi to 11r to amp?

Sounds good so far but will wait before jumping in.

I wonder what my MXR FullBore Metal petal to Epsi to direct box to the church pa would sound like.

Try it with bias please and let us know how it is, and would the Epsi be any hope for the GNX4? Still don't know what to do with that thing. LoL
