With out a second amp or kemper to be fair you are not going to get the full double tracking experience, some have hooked it up different to mine and have managed to get a good boost, lets try both the following options.
Since you only have ONE kemper, you could try what i do, i get a good boost on an FRFR (mission of cause )
Even with one kemper. Here can you figure whats going on here? I have a Morley ABY switch (since i run 2 kempers) See how the Mimiq
GOES INTO THE INPUT OF THE KEMPER (s)?
