Muting the Markbass multiamp is a pain because for some unknown reason, it changes the parameter / setting on the amp. My chain is simple: Bass----tuner----comp--- outboard preamp----drum machine---instrument jack of amp (aka input). Now if I turn down the outboard preamp and drum machine to zero, turn off the comp and tuner, is this the same as muting the amp? I am assuming that muting the amp is the equivalent of closing the gate to all inputs. Thanks for all information in advance.
