I’ve used the Cock Fight since Mid Nov 2016 and absolutely love it. Since last week though it has suddenly developed a problem of extremely low output volume (almost inaudible) when pre and post fuzz is engaged. It was intermittent at first, but now the fuzz is constantly soft and you can’t hear anything when engaged. It’s not the bias setting, I know how to operate and use that. When fuzz is bypassed, in the center position, volume is normal and as expected. The wah circuitry is working as expected as well. Is there something I can do to sort this out? Hugo.
