EarthQuaker Devices Disaster Transport SR – Delay, Reverb & Modulation

EarthQuaker Devices Disaster Transport SR

The EarthQuaker Devices Disaster Transport SR is a dual delay with reverb and modulation.

This pedal is an intense wash of lo-fi swirling tape styled echo.

Looking intimidating at first glance, it’s actually pretty easy to navigate. This is because the top row of controls are for delay A, and the bottom row of controls are for delay B.

Delays:

• A is a 600ms delay with modulation and delay
• B is a 300ms delay with reverb and both delays will  run separately, in parallel, or both!

Taking it one step further, there are also expression controls for the repeats on delay A as well as bleeding delay A into delay B.

Finally, the switching allows each delay used individually or in tandem with both true bypass or trails.

The EarthQuaker Devices Disaster Transport SR is not just a delay

Not just a straight delay, reverb, rhythmic delay, modulated delay and old school tape-style echo, the Disaster Transport SR creates sounds that result in a wild variety of effects.

For instance, these are ranging from warped records, clanging flange, smooth chorus, echoed out squalls and various other-worldly effects that blow your mind, man.

If you are a fan of old school tape delay and crazy lo-fi sounds, there are hours of enjoyment to be had every time you plug into the Disaster Transport SR.

Disaster Transport Controls

Delay A Controls

Time:

Controls the delay time from about 30ms up to 600ms.

Repeats:

Controls how many regenerations of the signal which can range from one single repeat through an endless wash into self oscillation. This can also be controlled via an expression pedal.

Mix:

Level control for the wet signal, with unity is around centre and anything above boosted. As a result, boosting this works great when using a distorted signal. But please keep in mind this is a gain control and results in a bit of hiss is normal when it’s above unity.

Depth:

Controls the intensity of the modulation, ranging from no modulation to all out seasick pitch bends.

Rate:

Controls the rate of the modulation using a LED for delay A which flashes in time with the modulation to visually show where the rate is set.

Bleed:

This feeds delay A into delay B, post reverb. Use this control for series or series/parallel operation to create rhythmic repeats, extra long delay time or an all out echo wash.

This can also be controlled via an expression pedal. When using the bleed, experiment with the repeat controls on each delay line which will result in different timing and textures.

Delay B Controls

Reverb:

Controls the amount of reverb added to the input of delay B.

Mix:

Level control for the wet signal. Unity is around center, anything above is boosted. Boosting this works great when using a distorted signal. Please keep in mind this is a gain control, a bit of hiss is normal when it’s above unity.

Repeats:

Controls how many regenerations of the signal there are. This ranges from one single repeat through an endless wash into self oscillation.

Time:

Controls the delay time from about 30ms up to 300ms.

Power

This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. Draws 107 ma.

We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies.

Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
