Are you having trouble hitting the 10-hole half-step blow bend on high-key harps (like Eb or F)? It takes practice but it also helps to have a harp that's set up in your favor.
The forces of nature (i.e. resonance) can act against you if the chamber size has its own resonant frequency that is not compatible with the note you want to play.
I make combs with chambers that are adjusted for the top reeds of Hohner harps in the keys of Dd and up.
Stock Golden Melody combs only come in long-slot dimensions although the reed plates come in two sizes just like Marine Band harmonicas. Expect a big improvement over the stock comb with these custom combs.
I recommend standard thickness for my short-slot combs.
