Lightbulb currently..

This bass has been in restoration since my last posting. It is getting a new neck graft as well. Because we were not sure who put the last bassbar in and because the top felt stiff, it was decided to take off the top and investigate. A bass of this class deserves any and all expense to make it 'whole' again.

After careful internal and external examination, the following was determined and assumed as well.

-- The bass is all original including the Scroll as the workmanship is believed to be a match.

-- The previous rib cracks have spread slightly past where they were cleated so, it's a good thing I had the top removed because these need to be re-repaired.

-- The top looks like it may have been re-graduated at one time. It is made of 6-pieces of wood and all of the cleats which are MANY, look to be about 50 years old or so, the same age as the bassbar. The back as well was at the least cleaned inside because the oxidation close to the corner blocks looks way older than everything else. Therefor we think all of the wood was cleaned and 'de-oxidized' if that is a word! The tint/color of the woods are still oxidized to a degree but look less old than the block areas which look untouched from its birth.

-- The type of wood used for the top which is fairly hard and stiff and the way it is glued up as well as being askew at the center center joint looks to be a Harpsichord top as used in that period and possibly made of Cyprus, not spruce. The top is also 2-toned in color, tan and brown like the heart and sap wood of a Cyprus tree which is native to Florence. The sap (outer) wood being mixed within the same pieces of the heartwood means they were cute from nearer the center of the tree and not the outer sap area usually used for the violin trade. This in itself would make the wood much harder than the outer cute. Being two-toned in color, this may have been pulled from the stock of glued up blanks for Harpsichords and given to the maker to use for a bass.

-- The top has been completely re-edged all around which could mean in time, it was quite chewed up. Also, most of the internal linings look newer than the bass. Possible done when it was last restored.

-- The pegbox shows quite a few repairs and modifications showing that it had at least 2 other sets of gears before the current ones on there.

With all this discovery from a closer examination, we believe the label might be original as well as the period of make and erasing some original doubts. Also, there were sloped shouldered basses made at that time but this seems to be made an an exhibition or masters test model for show or display.

Here are some pictures of the inside including the Top after it was repaired with new half edging, bass bar and some clean-up.

Nice bass. I like the FFs very much.

I don't get how the top could be made from a harpsichord top - if you mean harpsichord soundboard, then wouldn't it be way too thin to carve a bass top arching from?

I'm glad you're replacing the neck. I never did like that knurled knob :-)

Who's doing the restore work?

Yes Matt, I meant soundboard. The top inside a keyboard. I don't know what the thickness of the planks were for a Harpsichord 300 years ago but it was a piano restorer that made that comment. He is an friend of the restorer, Mike MaGee in Pittsburgh.

The pic from above is some of his work, the half-edging and the bass bar. Some fitting and trimming is yet to be done when the Top gets fitted to the Ribs.

From here, that top looks a bit like a viol top, sometimes made from bent planks fitted together. So I guess it could be made from a harpsichord soundboard.

Incidentally my godfather is Andrea Goble of Robert Goble and Sons in England

When I was there a few years ago I was shown some very nice instruments ... and some LOGS of ebony!

If possible, have them research Cristofori who invented the Piano from the Harpsichord. I think it was just 5 octaves. Malvolti was his apprentice in violins and he had another for the keys.

Here is the article that connects it all.
http://arteliutaria.com/article_cristofori_scuola.shtml

Unfortunately, all of the violin books were written before this research was done. Prior to this article, the history on Malvolti was limited. Now we know that for most of his working life, he was employed between Cristofori and the Medici family. This helps to explain why so little of his work is known. Maybe 4 Violins I have heard of listed and this one Bass that appears to be made as much for show as to be played.
