Hx stomp. Currently I use it with a passive DI box straight into FOH, however I'm probably going to start just using a jack to XLR cable. the DI box is really not required. I currently have it on a micro board with a 2 pedal footswitch which to be honest is abit overkill for my use on bass. I tend to stick to one patch. nice clean amp sim, switch 1 octaver, switch 2 filter, switch 3 scooped EQ for slapping. On the footswitch, one is tuner, the other changes to whatever i feel like.
It doubles up as my home guitar rig, so its pretty much a no brainer. all is velcroed onto a small board, that slides into the front pouchg of my bass case. can't really beat it.
