Apologies if this has been asked before, but I run an unpowered kemper to a Matrix GT800 (in stereo) and left/right to some Marshall 4x10's. My question is: do I crank the poweramp, and control volume from the Kemper master volume, or crank the master vol, and control volume on the matrix? Anyone any thoughts as to which is better/better sounding? Just curious!
Please & thankyou
