Dear all,

I've been wondering what the G2's Saturation and Overdrive modules have been modeled after. I really like the sound of it and I'm looking for an analog circuit that does the same. However, all I can find is various stompboxes for guitar that involve heavy filtering. This makes the output vary narrow-banded, but the G2 models seem to be different in this respect.

My guess is that the Saturation is modeled after a diode-soft clipper like the a Ibanez Tubescreamer, but without any of the filtering. And the Overdrive is probably a simple transistor overdrive. Can anyone confirm? And was filtering taken into account in the model? Or totally removed?

Best,

Rutger

As far as I know (and according to my personal experience when using these modules in many differing situations) the saturation and overdrive modules are simple nonlinear transfer functions, without any filtering stage.

What they are modeled after, I would not know. I however suspect that they are based on some mathematical formulae and not look-up tables. (Otherwise I can't see a reason why the overdrive module uses more DSP than the saturation module (which it does).)

cheers,
t
