Has anyone ever seen a bass machine like this?

[Alexis]

Hello everyone, a few years ago I bought an old Frontalini in poor condition and I have been repairing it little by little, when it arrived it had loose reeds inside, the wax cracked, a joint of the box with the soundboard detached and some loose bass rods , the dull celluloid and so on.... but what has caught my attention the most about this accordion is its bass system, I had never seen anything like it, the fact is that it works well and is very smooth and silent, but it has been Quite sensitive to the touch with very little finger pressure it starts to ring, you can play it perfectly anyway. To install the loose rods I didn't need to disassemble anything and not if I would dare with a machine like that, of the "normal" ones, I did disassemble and reassemble some of them. Does anyone have any idea if it is feasible to disassemble? I have read on this forum that the Frontalini machines were a bit problematic, but they were not the same as this one. Well, if anyone knows anything about this accordion, I would appreciate it. I don't know the name of the model or the year of manufacture either. I put some illustrative photos. greetings

Interesting, judging from the visible "points" below the cover it looks like a scrunched up version of a typical removable bass system. I've never seen one like this myself. Have you tried removing that aluminum cover to see what is underneath? I am assuming that it is only a cover and the rest of the bass mechanism is not attached to it, but it's hard to tell from the picture.

well like our friend from Romania explained, brevetto more or less
means "Patent pending"

which in this case, the patent likely did not arrive prior to
Frontalini going out of business

they made some pretty neat accordions though.. harder to find
one of theirs still in useable shape..

Well that is interesting. Obviously the "decoding" of buttons to valves is being done somehow in that top section. But how?

If you do wind up taking that bit apart, please post photos!

Bueno, eso es interesante. Obviamente, la "decodificación" de botones a válvulas se realiza de alguna manera en esa sección superior. ¿Pero cómo?

Si terminas desarmando esa parte, ¡publica fotos!

algunas fotos, creo que dejaré de desarmarlo más, por si lo estropeo.

Well, as for the manufacturing, for me it has some nice details, like the tool it comes with to remove the springs and remove the keys easily. It's a shame that its previous owner treated it so badly but it still continues to put up a fight and sounds pretty good. Well, the sensitivity of the bass to the touch is not that much of a problem and I could leave it as it is and get used to it, I bought it for very little money to be honest, I can't demand too much either.

As I suspected, it is a kind of shrunken down version of a normal removable bass mechanism, I'm sure there is a proper name for it but I don't know what it is. It's pretty nice that it leaves room for you to work on the pads without having to remove the mechanism.

Disassembling this thing is definitely doable if you are systematic about it, but if you don't have to, I wouldn't.

Gracias. Come "bass machine" normal, pero más corto? Interesante!
