Playing a 5 string through a big PA that can fully reproduce a low B without getting muddy like a bass amp? it's glorious. Any decent FOH person should have their rig set up to do whatever is needed to protect their woofers - me adding another high pass filter on top of that just limits low frequency stuff unnecessarily. A lot of folks use cab sims, but I personally don't want to muck up the low end with a cab sim, so I just use the rolloff of a low pass filter, and let the low end go to FOH unflitered. When you don't have a cabinet in the signal path, the upper treble stuff isn't filtered, so you need something to tame that (especially if you use overdrive!!!) - I use a Broughton low pass filter to do that. In my case, that's gain (clean), an overdrive (set REALLY subtle, and used sparingly), some eq (not a lot), a chorus (used on rare occasions), and a low pass filter. The thing you need to think about surviving in an ampless realm is that your pedalboard is your 'amp' - whatever you need to get a good sound to FOH you need to take control of - you want the FOH person to bring up your feed, and say 'that sounds good' without having to do much to it.

Once you figure out a few things, it's the only way to fly - the one gig I do where I still use an amp is essentially a coffee house vibe - I use a 110 cabinet for that, and that's more than enough. I've been doing about 90 percent of my gigs ampless for the last 6 years - a few hundred gigs done this way.
