I got this item for my Bard and it is still usable by Bards, even if the class is not mentioned. Great tool for Charm-pulling, which I finally mastered after some tries.
Stand in (charm)range of the mob that you want to pull out of a dense pack. Target mob, start casting the Charm spell and immediately (so while the cast timer of the Charm spell is still counting down its 3 seconds) hit fade: the counter for your CHarm spell will still run down its 3 seconds. Then when the Charm song lands, immediately fade again, BEFORE your pet gains aggro from any mob near him. Now you can simply walk away with your charmed mob trailing you. Or you can "/pet sit" him down, run to a safe location and then use the Ribbon of Empathy to summon your pet to you! Since your pet will run a lot slower then you (your Selo's will not hit your pet) the summoning method is good if you do not want to lose your pet halfway(pathing/stuck issues). If you only have a short distance to run to camp then you can do without summoning.
Once in camp, use an invisability spell (instaclicky if you can get your hands on one or else your invis song) and beat him down. This worked great for singling out the Quality Control bots in this quest: https://everquest.allakhazam.com/db/quest.html?quest=4433
