So. Y'all thinkin', "Who the heck reviews key label stickers??" Hey, it's a nasty job, but someone has to do it. So here goes: They stick. They're bright orange so you can see them. And who wants to fumble around trying to find those tiny embossed key labels on the cover, or actually looks at the front of the comb, where a lot of makers put their labels? (Kudos to Seydel, which does a good job of making harps with readable labels, but even for those, these big orange stickers are a good idea.) If you're thinking about cost, these work out to about 21 cents per label, which is like ... nothing. You can't even get two minutes out of a parking meter for 21 cents. But be realistic. I have a big collection of harps, but probably won't ever use the LLE or HAb stickers that come on the sheet. So make it more like 35 cents per sticker. Still worth it to have a readily visible key sticker on your harp. (You may be thinking, "But it doesn't look traditional. Little Walter didn't have any of these on his harps." But some day you'll be on the bandstand and the leader announces that the next tune is in Bb-minor, and you'll be fumbling around thinking "Which of these is my Ab harp?," and you'll be totally unprepared when the bandleaders points to you to take a 12-bar solo in 3rd position.) At the risk of starting an on-line flame war about stickers, these are a good idea, a good product, and worth considering.
