Tri-Dimensional Reverberation Machine

If you want to push the limits and take it further to sonic reaches that only you can uncover, then this is also your pedal. It’s everything you’ve ever wanted and needed out of a reverb.

Mode R: Room Reverb

At the shortest Length setting, the Room mode achieves a small, boxy room sound that gradually gets bigger as you turn it up.

Sets the length of the reverb, from small to large room.

Tames the treble in the reverb reflections.

Adjusts the level of the reverb.

Mode H: Hall Reverb

In Hall mode, as you increase the Length setting, it morphs into a Cathedral style reverb that becomes really big, boomy and echoey with distant reflections.

Sets the length of the reverb, from hall to cathedral style reverb.

Tames the treble in the reverb reflections.

Adjusts the level of the reverb.

Mode P: Plate Reverb

Turn up Length in Plate mode to get bouncy reflections that recycle and reverberate forever.

Sets the length of the reverb, from large plate to mega plate with nearly infinite reflections.

Tames the treble in the reverb reflections.

Adjusts the level of the reverb.

Operating Modes

Ledges has two operating modes which are indicated by the color of the Save/Recall switch. In Live Mode, the pedal will operate exactly where the controls are set and any changes will have no effect on the presets unless saved. In Preset Mode, stored presets are selected using the Preset switch, and the physical settings of the controls will be ignored.


Ledges has six available preset slots for you to save and recall your favorite settings. The settings for each of the three controls, the mode switch and the expression jack assignment can be saved and recalled in any of the slots.

Expression Control

Use any TRS expression pedal to take control over the LengthDamping or Mix. Different EXP assignments can be saved in each preset. You can also use Control Voltage with the EXP jack. The CV range is 0 to 3.3v.

Flexi-Switch® Technology

This device features Flexi-Switch® Technology! This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching.

  • For standard latching operation, tap the footswitch once to activate the effect and then tap again to bypass.
  • For momentary operation, hold the footswitch down for as long as you’d like to use the effect. Once you release the switch the effect will be bypassed.

Ledges is buffered bypass with tails. Power is required to pass signal.


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