For my live rig I have a small board with wireless receiver, tuner, and an Ampeg SCR-DI on.
I either run that into the front of the head, or the FX return depending on the room.
Broadly I am happy. It's a good setup and I like it.
However, I'd like to try some other Preamp/DIs to see what they are like. What have you tried and how did you like it?
