Regarding the Boss FV-500H pedal, the TRS cable from the Boss EXP jack must be split to TS to work in the EXP2 or EXP3 jacks on the Helix. Or, a TRS to TRS cable can be used as long as the Boss end is not fully inserted into the EXP jack. I have no idea why they changed this, as a TRS/TRS cable worked fine after calibrating the FV-500H for the POD HD 500 and 500X. Is there any way the Helix can calibrate or the parameters can be changed so that either mono TS/TS or TRS/TRS cables can be used in EXP 2 and 3 with a Boss FV-500H? Thanks.
