I'm considering switching from my Line6 G90 which just went out on me to the Shure GLXD for my bass. But, I have a couple of concerns: I'm interested in the stomp box (GLXD6) for my pedal board, but it does not include the built in charger that the GLXD4 has. So does it come with a separate charging station? That seems like just another pc of equip to carry and not lose! Also, does the built in tuner mute the signal when selected? I use a Boss volume pedal with a dedicated tuner out so that even if the pedal is "off" the signal still goes to the tuner for "silent tuning". Lastly, the options for instrument cables do not include any 90deg options, which I prefer. Will the Shure WA-304 work on these transmitters? Thanks for your help!
