I want to go POD HD500 to Boomerang III to FRFR or board, but the Rang output is stereo instrument level. I want line level. At inst level, the signal is to weak to use my K10 likme an amp. I have a Tech 21 Bass Driver DI. That let's me go from inst to line to FRFR, but it is mono. Any help? A passive DI is too quite as well, I think. I tried the POD at line level, but it clips the Rang.
