It is indeed the situation, Richard, and I find it difficult to understand how the major companies can be so reactionary as to persist with constant radius fingerboards, when the benefits of the compound radius are so obvious. Well actually I don't find it difficult to understand, I know what the accountant mentality is like ...

It is less of a problem on acoustic guitars, and the flatter the radius, the less of a problem it becomes, but the original Fenders, Teles and Strats, were a nightmare, with a constant 7 1/2" radius it was impossible to bend a note cleanly above the 12th fret.

Hence why Warmoth took the replacement Fender neck market by storm when they introduced their compound radius replacement necks.
