The pedal is designed to accurately recreate the SPX90 ER 2 Reverse Reverb effect, known for its use by Kevin Shields. The 3 modes include: ER2 - The main mode, which is very closely based off of the ER2 Reverse mode on the SPX. ER1 - An unfiltered variation of ER2. Clear, clicky, closer to the SPX's ER1 mode. Random - The delay pattern follows a more randomized curve rather than the swell-in of the reverse modes. In this mode, the Liveness control increases the feedback density of the delay signal. It is useful for a fast 80s style gate verb or can be turned up and used as high density, rhythmic version of ER1/2. Unlike the reverse settings, this does not directly clone the SPX90 "random" mode, though it was inspired by it. Thanks for looking! This effect pedal requires a 9V power supply with at least 100mA available. It is not compatible with 9V batteries. Quality isolated supply recommended for lowest noise and interference with other effects. Digital effects can hum/ring when daisy chained with certain fuzz pedals, even while bypassed. I run a daisy chain and have found this to be minimal with the ER pedal, however. Standard "true bypass". Pedal Info PDF
