Remember this little portable (even battery powered, if needed) rig?
I have a more compact set up than your setup... If I want to go keyboard-less..
Marantz Pro voice rover (battery power , Bluetooth and built in wireless mic system..)
No power cords or patch cords..
Just use my phone with tracks and lyrics, and the included wireless mic,,
Setup time.. turn phone on and turn the power switch on the amp on..
virtually seconds..
Marantz has wheels and tele handle...everything stores in the Marantz..
