I have a Gretsch Power Jet with the traditional Jet setup...master volume, neck volume, bridge volume, tone selector switch, and pickup selector switch. What really sucks (literally) is that whenever I roll off the master or the individual volumes, the tone because VERY muddy and rolls off almost immediately. It really makes it useless to me to play with guitar volume for a cleans to lead/crunch approach. Wide open though, the guitar sounds amazing. Is there anyway to modify that setup? I could actually live without the master volume if necessary.
