i've experienced the lifeless tone on guitar but on bass, so far...it's been big and booming..maybe it's just my playing style combined with it (i'm aggressive on the strings). but it definately has helped in terms of finger picking...i can actually pick faster with flatwounds and my fingers aren't as torn up with the flat wounds.
i'm tempted to try the guitar with flatwounds again just so i could try it direct in on bridge pickup...i think it might produce a cool tone.
okay...my post is done...goodbye.
