Ultra-tight and just as accommodating, the itty-bitty Electro Harmonix Pico Oceans 3-Verb pedal still tucks away a vintage spring reverb, a warm plate reverb and a rich hall reverb. Hit the Type button at the top and the LED indicator will light up in green, orange or red to let you know you've selected your reverb of choice. Via the Delay/Spring pot, you can dictate the pre-delay time of the hall and plate reverbs, but in spring reverb mode, this pot has a completely different function... The EHX Pico Oceans 3-Verb: Vintage Spring, Warm Plate & Rich Hall In Spring mode, the Delay/Spring pot determines the length of your virtual spring so you can shorten or lengthen it as preferred. Twist the Blend pot to strike the perfect wet-to-dry balance, tweak the Tone pot to darken or brighten up the effect and, when the trails are bypassed, you're treated to unlimited reverb. As a final treat, EHX have even thrown in a 9V power supply.
