Hi folks, my mate posted me his Uberdrive build that is not producing any sound. Apart from flux on the board - which I've carefully cleaned, avoiding the pots - I can't see too much wrong with it. I pulled it out of the enclosure and sat it on the Auditorium and it's still not making a sound. LED comes on, bypass was working in the enclosure. He's used 2N3904 transistors in place of the 2SC732s called in the BOM, is that ok? I checked the pinout and believe they need to be flipped around, hence looking like they're in backwards in the photos. Can anyone spot anything? What should I check next?
