Actually, high loss isn't the big factor.  Loading the crystal (or 
ceramic) element is.  It affects your lower frequency response adversely.

Of course, if you get the sound you want, then the point is moot :-)

If you put his RAW guitar sound on a spectrum analyzer, you'd see a 
definite loss of highs (like a "raw" Fender Strat, etc. - the "trebly" 
sound.)  Collins had an incredible guitar sound, but it was pretty 
"mellow", typical of humbucking pickups.  He played plenty of high NOTES, 
but that's not the same thing.

Compare his sound to Buddy Guys.  Buddy plays a Fender single coil 
guitar, and it has quite a bit of highs.  That's what gives it the 
"gritty" sound.  And ditto Stevie Ray and Jimmy Vaughn.

B.B. King plays humbuckers, and while he hits plenty of high NOTES, it 
has no treble.

 I use a cordless (actually, two of 'em - one for guitar, and another 
for harp.)  And yes, the audiences LOVE it when you "come to them".  
They go nuts when I lay down on the floor while doing a steamy harp 
solo.  And the audience IS paying to be entertained.  Music is just part 
of the package.  Give 'em what they want and they'll give you what you 
want (more work, more applause, and more money!)
