Hello, 1. I use a full AMP MODEL, a CAB MODEL and a MICROPHONE in the POD. 2. I connect to the POWERCAB 112 PLUS through the L6 LINK ports of both units. 3. I use the FLAT mode on the POWERCAB 112 PLUS. 4. I understand that the use of any of the VOICING (FRFR, LF RAW, LF FLAT) does not imply that you are no longer using the FLAT flat response mode, otherwise it would change to SPEAKER or USER IR mode.. 5. The use of FLAT mode with VOICING FRFR on the POWERCAB is quite disappointing usi
