Mold Spore Wah Tone Suck

[GibsonGM]

Can you post a sound clip of it?  I see you have another thread going....if you put it there, I (we) will come look at it!   Often this has something to do with a filter-related problem, perhaps a bad cap or something....

yes I can, I will record it in the next days and post it here.

Thank you so much

You are totally welcome   Your questions help others in the forum to find answers later!  It is a good thought problem (how to stop the tone sucking) and worth working on.
