  • 1.  which Hammerheads should I use?

    Posted 06-05-2018 16:50
    I have a new client that would like the hammerheads on both of his Gors & Kallmann upright pianos to be replaced. The pianos are 128cm in height, and did have a complete action overhaul about a decade ago (not by me) but never had the hammers replaced, as I think the client was happy with them then. He has asked me the following "I want the 2 pianos to sound as similar as possible with a tone closer to Blüthner/Bechstein than to Steinway. Much more of the mellow/warm/rich sound than the bright/harsh tone."

    I have the options of using one of three different piano hammer sets, for each piano, and wondered if anyone can give some advice as to which set would best suit these Gors & Kallmann upright pianos according to my client's request?

    1. Abel natural with hornbeam moulding
    2. Abel natural with mahogany moulding
    3. Abel natural impregnated lower shoulders

    Another question, should the hammers have underfelt or not?

    Thank you.

    Since you want to go with Abels, I would suggest you call Melany or John at Brooks LTD, and ask for their advice on how the hammers will sound on those two pianos. They can be reached at 800-326-2440.  They will give good, honest advice.

    Make sure the new hammers are not too wide and thus too heavy. I suspect of the three options you described the naturals on mahogany will be the most warm toned.

    Does it matter whether the hammers have an underfelt or not? Does it affect the tone if hammers do not have underfelt?
