JMI Vox AC10 add-on top boost?

[seven]

Hi there,

I am planning out a Vox JMI AC10 build/clone. The normal channel is known for being somewhat whimpy. Had a chance to play an original one recently that was just serviced and I would agree with that sentiment.

So I got to thinking about adding top boost to it, if that would be possible?

Based on some high level research, seems I can add it in a similar location as in the AC30:

What do y'all think?

It should be doable, why not?

Top Boost was not much more than a tone control add-on module, should work on more amps if inserted in a similar position.

Thank you JM. Do you think I would be able to have it switchable during operation, say with a DPDT shorting (make before break) type switch?
