I recently bought a second hand M9. Signal chain will be mostly be:
Guitar > shure GLXD16 > M9 > mixing desk/PA..
Occasionally it will be:
Guitar > shure GLXD16 > M9 > Amp
Do I need to put a DI box into the mix, after the M9 or does it not matter/need one?
(I will be using this with an acoustic guitar)
