Hello, My bass has jack (unbalanced) and xlr (balanced) outputs. Would it be okay to go direct from my XLR out into an XLR in on a pre-amp such as the Millennia HV-3? IF not, why not and what are the options...? Apologies if this is as basic as it gets, I've just never had an XLR out on a bass before. Cheers, Douglas.
