Hello,

The L/R channels should be relatively balanced regardless off the depth setting for each voice.

How is the TriceraChorus connected to the stereo loop of the H90? Are you using a Dual Mono TS > TRS cable from H90 outputs 3-4 into the TRS input of the TriceraChorus?

Does the volume balance change if you adjust the depth of the L or C voice?

If you turn the R depth to 0 and the L depth to 80, are you perceiving the left channel louder?
