FREE shipping in the USA! The #1 Echo is a digital delay with analog tone. It comes in a small die-cast package and produces the FINEST digital echo available. It produces up to a full 2 seconds of delay time. You'll be amazed that such a great tone can come out of such an inexpensive and small box! The #1 Echo is an instrument that will echo any note or audio event that you play through it. You can control the time duration that will be applied between the played note and the echoed note. The echo will sound exactly the same as the original. The delay time range is from 10ms up to 2 seconds. Additionally you can choose the number of times that you want the echo repeated. This is known as feedback, which has a dedicated control. As you start to use the #1 Echo, invest some time to experiment with the controls and how they interact. You will discover very interesting possibilities including double tracking (where the notes are a little offset) all the way to long delays that allow you to continuously play new lines on top of previous events. The longer the duration, the more possibilities you have to add new notes to the original. As you add more repeats with a longer duration you can build up complex textures that can be very effective. - EHX AC Adapter included Video courtesy of Electro-Harmonix
