The Eden WTDI World Tour DI & Bass Preamp is a single pedal that puts four bass tools in one box: a preamp, a compressor, an equalizer and a DI. RockBoard's PedalPedia describes it as a pedal designed to elevate your sound with expansive functionality, and for a bass player it covers the two jobs most often needed on stage: shaping tone and getting a clean signal to the front of house1.
What it does
The WTDI's four functions work together in one signal path. As a preamp and equalizer it shapes the tone going into your amp; as a compressor it evens out dynamics; and as a DI it sends a balanced signal to a mixing desk or PA. RockBoard's PedalPedia lists the pedal's effect types as preamp, compressor, equalizer and DI1.
Eden describes the control set as a seven-knob layout: "This seven-knob beast offers a wide range of tools to shape, mould, and sculpt your sound any way you see fit." The pedal also includes a Bass Boost function, which RockBoard's PedalPedia says helps achieve consistent, well-rounded tones even at low volumes, useful for quiet stages and rehearsal levels1.
Outputs and stage use
The output section is what sets a DI preamp apart from an ordinary preamp pedal. The WTDI carries both 1/4-inch and XLR outputs. No Treble's Kevin Johnson, covering the pedal's release, noted that these "allow you to go into a PA as well as directly into the power amp section of a rig"2. In practice that means one pedal can feed your own amplifier and the sound engineer at the same time.
Power, bypass and circuit type
A few of these details matter when fitting the WTDI into a rig:
- Bypass: the pedal features true bypass, so it stays out of the signal path when switched off2.
- Circuit: the circuit type is analog1.
- Status: the WTDI is available now2.
The WTDI is a preamp, compressor, equalizer and DI in one box1, so it is worth planning how it sits in your signal chain and how it is powered alongside the rest of your pedalboard before you slot it in.
Background and availability
Eden Electronics released the WTDI direct box/preamp pedal in December 2010, with No Treble reporting at the time that "The Eden WTDI pedal is available now" with an MSRP of $224.992. Eden also makes other bass-oriented gear, including the Eden Terra Nova Module, and the WTDI sits alongside the wider field of bass pedals, compressor pedals and equalization pedals that players combine on a board.

Questions
Is the Eden WTDI true bypass?
Yes. According to No Treble's report on the pedal's release, the WTDI features true bypass, so when the pedal is off your bass signal passes through without the preamp, EQ or compressor circuitry coloring it.
Does the Eden WTDI have an XLR output?
Yes. The WTDI has both 1/4-inch and XLR outputs. No Treble noted that these allow you to go into a PA as well as directly into the power amp section of a rig, which is what makes it usable as a direct box on stage.
What voltage does the Eden WTDI need?
Eden's WTDI runs on most 12 to 18 volt capable pedal boards and power cubes, according to No Treble's release coverage. It does not run from a standard 9V supply, so check what your pedalboard power supply delivers before adding it.
Is the Eden WTDI analog or digital?
The WTDI is an analog circuit, as listed on the RockBoard PedalPedia product page for the pedal.
How much does the Eden WTDI cost?
When Eden Electronics released the WTDI in December 2010, it carried an MSRP of $224.99, according to No Treble.
