The Keeley Electronics RK2000 Funk Siren Delay brings one of the most unusual early-80s rack delays into pedal format for the first time: the Ibanez DM2000 used by Trey Anastasio to create his signature “Funk Siren” sound.
The project began when Trey guitar tech Justin Stabler approached Keeley looking for a reliable replacement for original units that were now more than 40 years old. The goal was not simply to build another vintage-inspired digital delay, but to preserve the behavior that made the DM2000 unique while adding the control expected from a modern pedalboard.
The RK2000 retains a 12-bit digital architecture and a delay range from 1 to 1023 ms. That 1023 ms limit is particularly important to the Funk Siren technique. The Hold function captures the delay buffer and keeps it repeating indefinitely, allowing you to continue playing over the captured sound.
The other key element is Mod. Its LFO can move from subtle warble to huge pitch changes, with an effect comparable to physically slowing or pushing a tape reel. Combine Hold and Mod and you get the rising and falling sweeps, octave movement and dramatic pitch shifts associated with Trey’s Funk Siren.
The RK2000 goes far beyond that one signature sound. It is also a fully featured stereo delay capable of slapback, chorus, flanging, modulated echoes, ambient pads, tape-style textures and rhythmic delay.
Time sets the delay directly from 1 to 1023 ms or selects rhythmic subdivisions when Tap Tempo is active. Available subdivisions include quarter, eighth, dotted eighth, triplet and sixteenth notes.
Filter provides unusually flexible shaping of the repeats. Around noon it remains relatively neutral. Turning one way introduces high-pass filtering and removes low frequencies, while the other direction acts as a low-pass filter and removes treble.
Depth sets how far the modulation shifts pitch up and down, while Rate determines how quickly that movement occurs. Moderate settings produce chorus and warble. More extreme settings lead into pitch bending, flanging and full Funk Siren territory.
The RK2000 also offers true stereo operation with selectable Parallel Stereo and Ping-Pong modes. Ping-Pong sends repeats across the stereo field for much wider movement.
Modern control is extensive. There are five local presets plus up to 127 MIDI preset locations. An expression pedal can be mapped to the sweep of any knob, with independent heel and toe values.
The Remote input can externally trigger Hold and Mod or be configured for alternative functions, making it particularly useful with Keeley’s optional companion switcher.
Bypass behavior is also configurable. Choose true bypass or buffered bypass, then decide whether repeats stop immediately or continue naturally using Trails mode.
Although it began as a recreation of a very specific Trey Anastasio technique, the RK2000 ends up being something much broader: vintage digital delay, modulation processor, one-second sampler, pitch machine, chorus, flanger and ambient tool in one pedal.
Hold captures the current delay buffer and keeps it repeating indefinitely.
The pedal continuously records a complete 1023 ms window even when the Time control is set shorter.
Mod engages the RK2000 LFO. Combining Mod and Hold creates the pitch shifts and octave warbles associated with the Funk Siren.

One second of delay does not sound like much until you decide to never let it end.
