It's not difficult at all... my hearing is fine... and high frequencies don't make my pants leg flap
My rigs sound great in any situation so that wouldn't happen to me... plus the chances of anyone having the balls to even consider doing something to my rig is nil, tizzy or not.
How do I do this? By using gear that can coast through whatever gig I'm on.
Dumb question... if that really was an issue, why didn't you just plug directly into a DI? On the rare occassion I've had a soundperson not know how to pad a signal I've done that. Problem solved for that moment... doesn't address the problem of the soundperson not knowing what they're doing, which ultimately isn't my problem anyway.
There's no "if" about it, I do

Quite often... and my disappointments are few and far between.
My standards are pretty simple... the gear has to operate up to "MY" standards

. Seriously, I don't give a rat's patoot about industry standards, they may not be up to mine. I'm very anal about my tone, gear and most of all technique but not to the point where I think I need to second guess it.
When I can go out in the venue (indoors or out) and hear my rig sounding great to me, what else exactly would I need? When I hear my rig sounding great onstage and non-musicians and musicians alike are complimenting me on my sound, including no apparent lack of low end (and yes, I do work my low B), I should second guess that because...?

. Even more basic, when I get called back for gigs because the person who is paying me loved what I did, the problem is...?
If it ain't broke and everyone's happy...
I have no quarrel with people who want to focus on minutia, that's just not my thing. I take that out of the equation by limiting what I used to stuff that works... for me and my needs. That would include my amps, my basses and apparently my DI

. Most of all it's me understanding how to get what I want out of what I use. Gear that doesn't fit that model will not be used. As such, my gigging problems are pretty much nonexistent. I know that's unbelievable for some but it's true. I plug in, hook up and play. Just did that over the weekend and Monday night.. again. It's so predictable it's almost boring in it's reliability.
If the LMII didn't perform up to my standards I wouldn't use it. Period. I have other stuff that still works. If a feature didn't work up to those standards, I wouldn't use that feature. I have no stake in pretending the DI works any better than it actually does.
