I'm completely rethinking my rig. Bear with me. [at it's simplest...] I run a pedal preamp (BDI21) into a power amp (nuke3000). With just those two components the volume is fairly low, so I add in a rack compressor (Output knob adds up to +15dB). Volume issues are gone, no clipping anywhere, everything seems fine. Is this the right way of doing things? I assume there's some sort of impedance? imbalance between the preamp and power amp. What goes in the middle that matches the two properly?
