I have a 200W Yorkville 2x10 combo which I wanna use for recording....would you recommend that I get a bigger bass rig? I am willing to rent a 4x10 with a head.
You'll be fine with that combo. The engineer may or may not even mic your rig at all. Generally, the main bass signal for recordings comes direct from your bass to a DI box then to one of the studio's preamps or direct into the board.
