Diode Reference 'mover'

  Here it is...basically a speaker connected between diodes to ground [in a Diode clipper], your amp pumps air, the speaker is driven by that to vary [at whatever rate your amp and strings are vibrating] what would normally be the diodes ground reference.
  Totally untried and unverified, I'm looking for 'knowhow' as far as what anyone can read into why it would or wouldn't work, or implementation [should be very simple/easy to mod/de-mod] and results thereof...

It looks a bit wacky but a number of things spring to mind:
1) The speaker will be low impedance and won't generate much potential - why not use a (buffered) mic instead of a speaker - after all that's what mics are good at?
2) It's almost impossible to imagine what it might or might not actually achieve in practice.
3) How close would the speakers have to be to achieve any reasonable effect?

I think this is an experimental idea so you should probably do just that i.e. experiment and see what comes of it.

VERY interesting!

If both speakers were mounted in the same box without any ports, the dampening of the cone would do something rather unique to the clipping.

There is also inverting the phase of the speaker in the diode path as well as the use of a small speaker there while the main speaker is much larger like a 4" and a 10".

If you wanted to use 2V to drive things to get clipping, you woul have to drive it with....

(ohms law time)

W=E²/R

...or...

Watts = Desired Voltage² / Speaker Resistance

...or...

W = 4/8

...or...

W=0.5

Any little integrated amp should work fine.

I think Dave has a good point about trying a mic in there. It sure works great for noise canceling headphones.

Thats genius Pete!
