This is what I have in mind; play solo all the time plus occasional backup music on a USB stick from the digital accordion and take advantage of the 3D stereo image of the Spacestation V3 while strolling around totatlly wireless. The missing link is a robust stereo transmitter. Once I get my SSV.3 I will try my WI Digital system and two AKG Guitar bugs though I would not like to deal with two AKG receivers.
It all depends what do you want with it. Are you playing left and the right side at the same time?? If you play with a band or a keyboard player and you just use right hand for solo than it really does't matter much. Even if you play left hand bass it wouldn' mattet that much. I mean ,if you want to have separate control for bass and solo that you might as well get something,otherwise it doesn't matter.
