Spring Reverb Guitar Bass Effect Pedal True Bypass You hear that EVP, bud? It's the all , extra spook-tacular, the calling out from beyond the void! The pedal is our spooky take on the haunted amp-top spring reverberation units of yesteryear. This creepy analog/digital spring reverb emulation machine boasts a terrifying 30ms - 150ms of pre-delay, controllable via the Attack knob, for everything from a quick, rockabilly slapback, to viscous pools of ectoplasmic reverberations. When playing , you'll hear the tortured trails of the reverb,resulting in more of a slapback, or sound. Legato playing reveal a massive ambient "depth" that fattens up the sound - and look out it's right behind you! Phew, that was close. The Dwell control sets the length and thickness of the decay,which is to say that it controls how long the disembodied spirits of notes no longer with us float through the ether; at the maximum setting, it decend into an infinite loop of self oscillation. The Depth sets the intensity of the reverb, which you probably know as the wet/dry mix, but we like to think of it more as how scary the overall effect is Controls Attack: Adjusts the length of the pre-delay, from 30ms at minimum to about 150ms at maximum. When the Dwell is set to self-oscillate, this change the pitch of the oscillations. Dwell: Adjusts the length of the decay. This start to self oscillate around 3 o'clock. The pitch of the oscillations can be changed by turning the Attack control. Depth: Mixes in the wet signal with the dry. is around noon and everything after is boosted.
