So I want to get a multi fx rack for my triaxis and 2:90. But I'm not sure if I should use the effects loop send/return on the triaxis or not or just run out of the triaxis, into the effect, then into the 2:90. It seems silly to have an effects loop on a 'preamp'. But I suppose I could control the loop with the triaxis rather than turning it all off on the multi effects. How are you guys running rigs like this?
