Every once in a while when discussing older instruments there is mention about how huge some of them were. 43"+ string lengths, 5/4 (by current standards) bodies, etc. and there is talk about how some basses have been altered to meet our current demands at some point in their lives. We also hear about how "church basses" or other smaller than basses but bigger than cello instruments have been modified to become cellos, how most of the Stradivarius violins have had their necks reset for steel strings (among other work) and some other interesting things, but I'm trying to stay relatively bass orientated. I know that neck resets and new necks with or without a scroll graft are fairly common, and I have seen photos of basses that have been through large scale restorations where there seems to be more new wood than old. From most of the talk I have had with luthiers and makers, currently there seems to be a lot of emphasis placed on preserving the original maker's work, which has me making the assumption that many of these basses that shrunk did so at some point in the past? Is this an operation that is still occurring? What makes a bass a good candidate? Does deciding it should have a shorter string length and potentially altering the outline to make it more playable greatly impact the value of the instrument? Maybe someone has some resources to point me towards to help satiate my curiosity?
