Hey everyone! So I have a reissue polychorus I picked up. I am having the same issues with mine as listed above with the loud volume increase when engaged. I tried ajusting the trim 2 and 3 with no results and now the pedal is not functioning properly. The chorus is coming out of the flange setting, and the flange is coming from the filter matrix setting. Can someone take a pic of their trimpots and post it for me? Or can someone post a better explanation of what each trimpot is used for? Any help would be greatly appreciated and thanks.
