Hello,

I’m completely new to the forum, and I’m only just starting to learn the CBA.

I recently bought a nice little 48 bass accordion. I was hoping the bass layout would give me:
major third | tonic | major chord | minor chord (i.e. E | C | CM | Cm )

But unfortunately, it is set up as :
Tonic | major chord | minor chord | seventh chord

Which, I find a bit limited for playing bass runs...

So my question is, can it be modified? And how ?

Many thanks in advance for your help !

Robin

You would have to change pistons, pallet placement, & reed blocks. Not worth the effort, labor, & cost.

Somebody on here will have the technical know-how to answer your question Robin.

As it's 12x4 I personally would want tonic, major chord, minor chord, 7th. But I'm not you.

Perhaps the whole unit could be replaced (from a scrap accordion perhaps) with what you want, but that might be expensive, even if you can find the configuration you want.

A custom job certainly would be very expensive (I know from experience).

In reality It might be cheaper to trade it for exactly what you want.

Good luck which ever way you go.

Thanks for your replies!

Mm, that's a pitty...

It’s a Hohner Cornelia I (B-Griff). It’s a lovely little instrument, very compact (29 x 27 x 18 cm), yet with a full 3 voice (LMM) treble side. That’s why I would be quite keen to get the bass side sorted out… Seems like a nice instrument to travel with. And I know I would definately use bass notes more than seventh chords.

All my 48 (4x12) are: counterbass / bass / major / minor
And yes, I would like to have at least one with your bass layout: bass / major / minor / seventh
But as Longshore says, I'm not you ...
