Ibach and Brinsmead also made very good overdamped pianos and there are many German overstrung overdamped pianos of tolerable quality. Certain of the good upright makers such as Broadwood, Bechstein, Kirkman opted very early for the underdamper mechanism and never used overdampers. Brinsmead used underdampers in the 1860's and his patents show underdampers but he continued to produce overdampers even for very fine pianos until quite late in the century. Generally speaking only the Germans produced overdamper pianos with pretensions to high quality and 95% of overdamper pianos found in England are at best ordinary and at worst broken up in the great piano-smashing years, though a few remain. A neighbour called me in to look at hers the other day and it was very ordinary and valueless but playing fine and quite tunable and not even bad-sounding. I told her to advertise it in the paper and it will be perfect for a beginner and give no trouble. However, all these pianos have a pretty normal tape-check action; the Englishman Wornum, incidentally, should not be credited with this - it was invented by a Frenchman and copied by Wornum. Before these, there were pianos with the sticker action and the Costa action and these are usually truly awful. Apart from the different feel of the weighted dampers, as opposed to the sprung underdampers, the overdamper arrangement has the advantage of silencing the overtones more efficiently than underdampers; the problem is that the low partials are not so well damped, but when well set up, especially the Blüthner, the damping can be quite tolerably good. As to tuning, I've never heard anyone raise it as an issue. Most tuners in England, and all the tuners I have ever employed, tune without the aid of any electronic acronyms and use a Papps wedge. I use a wooden Papps wedge for all uprights, though I admit I don't like tuning uprights at all. Papps, incidentally, must have been quite an interesting chap. I think he was based in Portsmouth (Barrie ??) and he invented a solid steel wrestplank with holes in the shape of a rounded wedge. The wrestpins just sit in these holes and the tension of the strings is sufficient to pull them down towards the point of the wedge where they are gripped solid. Tuners who have come across these pianos say the system works fine contrary to all preconceptions. I've never come across one but I expect Barrie has. JD
