Yamaha E1010 Analog Delay Effects Pedal but inside there are springsReleased in 1978, this is a rich, warm analogue delay and versatile chorus delay, plus some killer flanging on the tight delays. We like the sound of this unit described by some as syrupy, it is also capable of some good, dubby self oscillation as well.
