I plugged in my Q-Tron this evening - the first chance I've had to do so in a few weeks - and poof: the effect does not work. It operates in bypass - quite nicely, I might add - but not when the effect is engaged. I tried swapping cables, swapping power supplies (with that of my BMS, as they are identical), and ran it by itself (without the other effects in my loop), and no dice. To say the effect is fried, at this point in the post, is premature. However, when I opened up the bottom, to see if it had indeed scorched, lo and behold: at three points on the board, there were slight discolorations - trace amounts of a dark brown (the PCB is green). And when I smelled it - burnt circuit boards emit an odor - my worst fears came true. I took it to a more knowledgeable man in the field of electronics and electrical equipment, and he confirmed my suspicions. What could I have done wrong? And how can I be sure that this doesn't happen again?
