Thought I sent this yesterday. The fact that I just found it in my drafts
folder suggests I was mistaken.
Not sure if it's still useful to you, but...


My son had one very much like this

As you suggest, the full volume output was near-enough horrible. But I
suspected at the time
that it had more to do with the cheapest microphone and speaker available.
In your application,
the speaker and microphone would need to be cut out anyway.
