My wah has become unresponsive on my AX2 212. It comes on, but the pedal does not change the frequency of the wah.

There was a thread in the old forums that identified the possible fix and the part I needed to change out (an 8 bit converter I believe) according to Lemmie who helped everyone out.

It was a simple swap out of this specific A/D converter I think in the amp head.

Of course we can not access the old archived forums from last year the last I checked so I lost the specific instructions about the procedure and part to replace to try and fix this. Not happy when I came back here and saw the new forums with all previous data destroyed.

Does anyone know what part this might be and where it is located in the head?

The amp works fine otherwise-all patches without a wah are fine.

The volume pedal works fine.

Any help is appreciated. I know Lemmie headed for the hills after the forum change so am wondering if anyone else knows what this part replacement is.

It seemed pretty common.

I do not suppose there is a way to now access the old archived forums is there?

There was not a couple months ago. Pretty surprising that Line 6 would make the switch and dump years of knowledge.
