BOSS DD-3

The BOSS DD-3 is a remarkable digital delay pedal with three delay modes and a very interesting hold mode. It's the entry level stompbox in the BOSS DD series.
So what's it all about?
If you've looked at the photo, you'd probably figured: the "MODE" knob, the last one, controls the delay time range that the "D. TIME" knob controls. The first position allows the "D. TIME" knob to control a range between 12.5ms and 50ms, the second position allows for the control of the 50ms - 200ms range, lastly, the third position allows for control in the 200ms - 800ms range. The "HOLD" option holds your delay forever allowing you to create some interesting effects.
The feedback knob controls the intensity of the delay.
Finally, the level knob is quite self explanatory.
