Keeley Electronics has introduced the RK2000 Funk Siren Delay, a pedal based on the revered Ibanez DM2000 rackmount delay, a classic from the 1980s.
If you’re a fan of Trey Anastasio, then you’re familiar with the DM2000 rackmount delay. Trey uses it to create an ambient loop called the Funk Siren. In 1983 it was called the most over-engineered delay of its time.
This unique delay, with its Hold and Mod feature, is now available in pedal form for the first time. Justin Stabler, Trey’s guitar tech, asked Keeley Electronics to recreate the vintage delay because Trey’s aging 40-year-old models were increasingly unreliable.
One of the defining features of Keeley’s RK2000 is its modulation section – an effect that is so dramatic it’s been likened to slamming your hands against the supply reel on a tape deck. The RK2000 Funk Siren Delay features presets, remote switching of Hold and Mod, expression pedal over any control, ping pong pitch shifted delays, and MIDI control. The RK2000 Funk Siren Delay is the first-ever pedal recreation of the legendary DM2000 rackmount unit. Designed to solve the reliability issues of 40-year-old vintage gear, this pedal delivers the exact “Funk Siren” ambient loops made famous by Trey Anastasio.
Like every Keeley pedal, the RK2000 Funk Siren Delay is designed and manufactured in Oklahoma, USA. Engineered for the working musician and voiced for inspiration.
