I started with an amp and cab, then left the cab at home, then tried a Behringer bddi mainly for the xlr output to the desk previously on the Genz heads, then decided I preferred the sound when it wasn't switched on so I've got a phantom powered di box, a lead and my bass!
Digital desk allows me to send the bass signal to two channels, one mixed for FOH, the other for the in ear mixes only.
EBS_freak sorted it all out, I wouldn't have a Scooby!
