Trey Anastasio’s Legendary Funk Siren — Now in a Pedal Trey Anastasio’s mind-bending Funk Siren is a hallmark of Phish’s most epic shows. Housing a 1,023-millisecond delay and a phrase looper with Hold and Mod, the Keeley RK2000 Funk Siren Delay allows you to achieve this spellbinding sound, which traditionally required the creative deployment of a vintage rackmount digital delay. Designed in tandem with Trey’s guitar tech, the RK2000 is a drop-in replacement for the rackmount unit, replicating not only its distinctive 12-bit personality but also its analog character. Additionally, the RK2000 reproduces the original unit’s multi-octave Modulation effect, shaped by a unique Filter knob, while the Input gain knob adds tape-esque saturation to your repeats.
