EarthQuaker Devices

The Ghost Disaster is a combination reverb and delay pedal made with the Disaster Transport Jr. Delay pedal and the Ghost Echo Reverb.


  • Reverb - Turns the reverb side on/off

  • Delay - Turns the delay on/off

  • Bypass - This is the main on/off switch. You can run the pedal in true bypass mode by selecting delay on, reverb on or both on on the series and using the bypass switch to turn Ghost Disaster on/off. You can also run it in buffered bypass mode by leaving the bypass swith on (LED lit) and using the respective switches for delay and reverb. When using in buffered bypass mode, the delay will have trails. Set the repeats control anywhere up to noon for trails that decay naturally , between noon and 2 O'clock for trails with near infinite repeats and between 2-3 O'clock for trails that result in an ambient wash. Anything above 3 O'clock will decay into self oscillation.


  • Mix - Sets the output level of the effected signal. This should be treated as a gain control/master volume for the delay line. Unity is around noon and everthing above noon will boost the delayed signal louder than the original. This is a gain conrol so, like any pedal with alot of gain, a hint of noise and distortion at max setting is completely normal.

  • Tone - Most delay filters are heavily filtered at the output to remove the clock noise and other unwanted hash that is common from extending the range of delay time beyond the limit of circuitry. This usually leaves the delay sounding dark, muddy, and disappear wen hitting it with dirt. The delay in the Ghost Disaster has done away with alot of the heavy filtering and replaced with a tone contol which allows you to choose the overall tone and noise factor of the delay. The tone control is at it's darkest fully counter clockwise and brightens as you turn it clockwise. A good rule of thumb is to leave the tone control between off (fully counter clockwise) and noon at longer delay times. This will remove all the common noise from hyper-extending the circuit.

  • Time - From about 30ms fully counter clockwise to about 625ms fully clockwise.

  • Repeats - Sets the regeneration of the delay line. From one single repeat fully counter clockwise, subtle repeats around 9 O'clock, strong naturally decaying repeats at noon, near infinite repeats around 2 O'clock and full on self oscillation fully clockwise.

  • Depth - Sets reverb intensity (level of wet signal).

  • Dwell - Enhances the length of the decay. As the depth s increased the dwell should be decreased. Increasing the dwell with the depth set high will result in self-oscillation due to the signal slamming the reverb "tank".

  • Attack - Sets the pre-delay of the pick attack on the wet signal only. From 50-325ms of pre-delay on the reverberated signal. Using this in conjunction with the time contol can make some nice rhythmic delays.

  • Power - A standard regulated 9-volt DC power supply with a negative center 2.1mm barrel. Do not run at higher voltages! Does not use batteries. Current draw is around 100ma.
