Or, more simply perhaps... through your bass/pedalboard/DI/Whatever you could get a tone you like, and enjoy playing to...and then let anyone on FOH work with that the same as they would your amp sound. This is where stuff like the MXR/Sadowsky/Noble Preamps/DIs come in. My favourite thing about IEMS is that what I'm playing to is representative of what I'm sending to the PA, so I can be reasonably aware of how the changes I make apply to the FOH. I don't really want what I'm hearing to be different to the DI feed.
