I have read here on MN that due to these enzymes, once pineapple juice is used it's difficult to glue surfaces together again. but perhaps there is an effective way to clean out the pineapple juice so the crack can be closed again sucessfully...

the symbol near the adjuster is reminiscent of the bows in this discussion.

I have it scanned, I will PM it to you. Nice Cello!

here's one in my shop, I don't know where the old instrument was made.

American church bass perhaps? Looks a bit too recent, but a friend has a similar one that appears older, in similar condition.

Hi Don, Not to derail the thread, but can you tell me briefly why vibrations in a gong is non-linear and in a violin it's linear? Sure, if you want to raise the pitch of a violin string you tighten it, that's a very linear relationship. But if you want to get rid of a wolf tone, or eliminate some harshness, or make another tone 'adjustment', what do you do? You tweak any of the 1000 variables, some work, some don't. Doesn't sound linear to me. Or take bowing, we all know there is a 'sounding point' or sweat spot that works. If you move the bow closer to the bridge the tone crunches into a bunch of random noise, which I assume one would call non-linear vibration. Just askin'

Ditto, avoid the seller, and ebay for that matter.

Hi Reguz, Although it's true that tightening the string stores energy as potential energy, my layman's understanding would be that this is not released when the string is bowed. what is released is the energy just imparted by the bow. But at different tensions there MAY be some difference to how a violin responds to this immediate stimulation. Like Don says, we have not seen any evidence of this...

I believe Melvin's point is that 'normal' mid-range densities do not achieve the interesting tone colors he's pursuing. I remember an intriguing quartet performance where the first violin had a Guad, 1758 I believe. I was a mere 10' from the action, and that violin was sweet as honey; impressive. But it didn't seem possible for the player to achieve an aggressive tone no matter how much he flogged it. Maybe that was intentional, but I remember thinking that something was missing.

We know that humidity also affects the bow hair and the bite of the rosin. could be partly the bow? just a thought.

unless you are able to show some pictures you will not get meaningful help here IMO. You could very well end up paying 10K for a Chinese import with fake label, as I'm sure you've gathered by now, reading other posts. good luck!

You could look at auction houses, but not everything labeled Testore is the real deal. Old authentic Italian instruments are not lying around for the taking, as you can imagine. I wonder how many Testore cellos there are in the world? And speaking of restoration, such instruments should really be entrusted to a reputable shop who is (hopefully) going to do it with the proper care. I'm sure you know that already.

Jacob is asking for this dimension I believe, I can't really see that accurately with the orientation of the ruler.

judging by the reflection in the area missing varnish, I'd rather say the 'ground' is exposed, not the raw wood. I imagine someone with experience could touch it up some, nothing wrong with some patina here IMO. Otherwise, keep enjoying it by all means.

Having purchased the collection of a delusional restorer many years ago who tried to do just this, I can tell you it's not going to work. Simply delusional, sorry. He ruined a bunch of instruments. Luckily I knew what I was getting, paid bottom dollar, and put them into school use, where many are still functioning today.
