Ok, fair enough.

It's not really an issue when I'm at home, but I take my dmgs travelling a lot so having volume control is nice then.

This will just have to be a studio only dmg.

Thanks for your help!

You could replace the volume pot if you really really needed headphone support. Otherwise, you'd be better off performing all volume editing with your mixer. You'll have far superior adjustment options on your PC or even hardware mixer.

Ok that worked! I moved them to pre pot and the crackling is gone!

That's progress!

So am I out of options for getting volume control?

I think your pot is shot. All that water damage can't help either.
I suggest moving your wire to the prepot locations and testing for crackle again.

Post.

Here is what I have:

It doesn't look like its in the best of conditions to me. But I don't know how much of a problem that is.

Did you perform the pre-pot mod or post-pot mod?

I installed a prosound mod today, for the first time ever, to replace one that was crackling, particularly when adjusting the volume.

The new mod I've installed is doing the same. So I'm guessing maybe that wasn't the problem.

Does anyone know what would be a common cause for this issue?

Any help would be much appreciated. This is my first time modding anything.
