Trey Anastasio’s Ibanez DM2000 16-bit rack delay inspires a echo/filter/modulation machine that goes way deeper than simple repeats.
Spoiler alert: the new RK2000 Funk Siren from Keeley Electronics ain’t your ordinary delay pedal – and that’s a massive understatement.
Designed in collaboration with Trey Anastasio and his guitar tech Justin Stabler, the RK2000 is based on the iconic Ibanez DM2000 rackmount delay, a classic from the 1980s and an integral part of Anastasio’s sound in Phish and other projects.
The RK2000 delivers the exact “Funk Siren” ambient loops made famous by Anastasio, with rock solid reliability, a ton of modern updates and expanded functionality, including adding modulation to your delay, tap tempo, full MIDI integration, five presets, expression pedal control and more.
And did we mention that it also happens to be a great sounding delay pedal? But that’s just the tip of the iceberg.
“If you're looking for a simple slap-back delay, this is NOT your pedal” Robert Keeley confesses with a laugh. “This is WAY more than that. But if you want to be the master of the universe, sending guitar notes into outer space, then gently recovering them and doing all kinds of insane stuff, then this is the pedal for you. If you're a Sonic Explorer, this will be your best friend.”
During a career spanning four decades (and counting!) Trey Anastasio has defined his unique sound with virtuosic playing and a fun-loving, adventurous approach. His choice of instruments, amps and effects are all part of that ethos – and his affection for the Ibanez DM2000 has been a constant throughout. Now you can tap into that 1980s-vintage wellspring as part of your sonic signature.
At its core, the RK2000 is a studio-quality stereo delay pedal with up to 1023ms of delay time, a dedicated Hold function for infinite repeats, and an LFO-driven modulation section capable of everything from subtle warble to “tape-reel” slams. And, of course, it nails the signature “Funk Siren” pitch quake that Anastasio’s fans will instantly recognize.
With a ton of functionality and flexibility at your disposal, you’ll find an enormous array of sounds and textures. The key features include….
Modulation: a standout feature – and you can get pretty wild. Use the Depth knob to control how much your delay pitch shifts up and down. The Rate knob controls the speed of the modulation effect, ranging from syrupy slow to hyperactive and intense pitch warble.
Filter knob: a simple and surprisingly powerful tool to shape the tone of your delay repeats. At noon, the filter is neutral. Turn left to cut bass or turn right to cut treble.
Presets: you can store your settings across five local presets or 127 MIDI selectable locations.
Phase of delay feedback: the pedal provides a two position button for toggling the phase of the delay feedback. Blue is normal. Red is inverted (180 degrees)
Tap tempo and subdivisions: use the left footswitch to set tempos on the fly
Hold function: use the right footswitch to engage the hold function and the current delay buffer for infinite repeats
Expression pedal: a TRS expression pedal can be mapped to control the sweep of any single knob on the pedal.
