Here is a sound of playing a bass through a broken Boss DD-5 (digital delay.) The signal buffer is screwed on it because I used an improperly rated walwart and fried the circuit.

Sound will only pass through if the input is driven hot. It gives a weird gated feel to it. Plus, the delay isn't working correctly either. Enjoy!
