Apart from when I drop them on me kitchen tile floor, they do seem to chip around the corners.

Anyone else got this on Golden Melody?

The plastic is too brittle and not hard enough. I never had this problem, but I heard when you want to cut the beams between the tines out, there's a big chance of breaking off the tine.

The plastic of Sp20 combs is simply softer.

Remember, most plastic combs are poured out as a liquid first (often petroleum based) into an injection mold, and unlike the combs from the Seydel 1847 Silver or the composite comb of a Suzuki Manji, the majority of plastic combs are hollow on the inside and definitely NOT indestructable and from temperature extremes, they CAN warp or crack and because unlike the combs on a Manji or 1847 Silver, which are real dense to approximate wood, a hollow comb like that can chip and crack, plus they can come from the factory with bubbling on them and so anyone who thinks plastic combs are perfect and indestructable, think again!

Remember that those comb edges are under knifelike pressure from the edges of the coverplates if the coverplate screws are tightened hard--it reminds me of flaking chips off flint to make stone arrowheads/knives, etc. Drop it on the edge of that coverplate and that's enough force to chip a divot off; you can even do it just by overtightening the covers. Other coverplates with flat flanges at the ends like SP20 or Oskar don't have that problem.

These new anti-spam prompts could be clearer on the upper/lowercase issue :)

The problem is amplified when you open the backs of the GM. There's even more pressure on the left and right back edges with no middle support after bending it back. I don't know why they don't just change the comb material; it's the only harp I know of with this problem of chipping.

A big problem with a lot of players is the fact that many players often grip their harps FAR TOO HARD, almost with a force like they're trying to strangle someone to death and if you see harp cover plates constantly getting crushed by some players, there's your obvious answer and this also puts excessive stress on the comb, and made even worse when they overtighten the screws and unfortunately, quite a few players are guilty of doing exactly that. Also when you overtighten the reed plate screws, besides stripping the screws and causing huge air leaks, overtghtening those screws can both warp the comb, the plate as well as cause chips.

Hmmm, I just thought about it a litlle and deducing from one of harpwrenches comments that the comb matierial has an effect on the sound it could be the the brittle material of the GM comb makes the sound crisper... just speculating.

Comb material effect on the sound is a lot more subtle but even tho at one time I would've argued comb material heavily affected the sound at one time, I now feel that cover plate design has more pronounced effect that the comb material, tho again, with comb material, it's so much more sublte to the point it sometimes isn't that noticeable, but still, the biggest factor is the person playing it more than anything else.

@Haronicanick -- Unfortunately, I speak the truth and certain covers are gonna be more susceptible to getting crushed more than others if one grips them too hard.

Bob, I think you have just answered my original question!
I must lighten up!

I never liked the way stock Golden Melody combs chip either, so I switched to colorful custom combs which also makes it easier to distinguish between keys. However, I believe we will see some positive changes coming from Hohner in the near future, especially with the Golden Melody.
