I just got the delay looper pedal. its awesome. experienced one issue playing live where it locked up and if I bypassed the signal it cut my bass off. had to reset the power and it worked again. maybe a grounding issue? who knows. anyways my questions are is there a serial number for the pedal? nothing inside it. and also I want my delay to trail off when I bypass the pedal like a boss dd7 can do when you hold the pedal down and plug it in? there has to be a setting for this. honestly its really dumb to have a delay that wont fade out when its turned off but instead just cuts. sounds un natural and lame. any ideas?
