Hi all. I am looking for a Di that has dist level and or blend. Has two or more inputs as I use 3 basses live with different tunings. Also i will be switching not just before a new set for a different tuned bass but between songs on occasion. So i need to mute from the pa sound. Would i need a mute on the di or would the tuner out when activated mute for my bass switch. Thanks. I have been looking over the web so much im wearing out. Could i use a AB box before the Di ?? Thanks
