| Problems with the back come in a variety of
forms, but stem largely from the stress put on the instrument by the strings,
and/or the shrinkage of the wood used to build the instrument.
This is often compounded by poor string choice, where modern strings, designed
for the more powerful US archtops, are fitted to these old instruments. The
other big factor is the hide glue used on these old instruments, which is very
susceptible to the vagueries of temperature and humidity, and
particularly,
central heating. |
