This is the latest video in Electro-Harmonix's excellent Effectology series - Reverb Tricks.
In each episode of the series, studio artist Bill Ruppert demonstrates a variety of effects using just a guitar and some EH pedals.
In this video, Ruppert focuses on reverb effects. For each one of the four sounds in this video, the reverb was positioned in unusual places within the signal chain - proof that there is no one correct way to order your effect pedals.
EHX Pedals featured in the video include the Soul Preacher, Holy Grail, MicroSynth, English Muff'n and Stereo Memory Man.
Updates on the Komplex Sequencer and nice little explanation
